Karrier S-Trail Radials with Automotive-Grade Tread

Kenda Karrier S-Trail Tread Vs Standard Tread

Unlike standard trailer tire tread, which has solid, continuous ribs, the automotive-grade, computer-generated tread on these Karrier S-Trail radials has ribs with breaks. These breaks allow water to run off to the sides. The Karrier S-Trail tread also has sipes. Siping is a process in which thin grooves (or sipes) are cut into the rubber of the tire. The grooves channel water away from the tread so that the tire makes better contact with the road. Both of these features greatly improve traction during wet, snowy, or icy conditions.

Karrier S-Trail radials are constructed with double steel belts and full nylon plies for increased durability and endurance. The premium rubber compound materials of this tire help disperse heat.

Beveled Stud Holes

Beveled Stud Holes Front and Back

The stud holes on this steel wheel are beveled to ensure that the wheel stays tight against your trailer hub. This also eliminates the need to constantly retorque the lug nuts.

Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.

Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Arrived as scheduled. Upgraded retrofitted jetski (kayak) trailers bias tires to these radials. Bearings and tires were the first items to check off tight lines all.

I have them on a trailer that I use for multiple activities. Not too much weight on it. I use it about every other week from spring through fall. My only issue is that they do not have a speed rating.

Thank you for your review! You mentioned the tires didnt have a speed rating, but I was able to find that specification on the website and wanted to let you know what it is. Our site says these have an M speed rating, which means the maximum speed is 81 mph.

GREAT CUSTOMER SERVICE!!! Thank you Matt! Matt helped us find the right product. We ordered this spare tire along with the CE Smith spare tire carrier for our pontoon yacht club trailer. Great quality spare tire. Also, the items we have ordered are shipped and received quickly!

- AM31199DX

I purchased these tires hoping they would perform well under tough situations like long hauls and gravely terrain launch sites. These radials are wearing three times better than previous 10 ply rated bias tires. Excellent product and am well pleased with my purchase. Again thank you .

Your radial tires are awesome. I’ve put three times the miles on these as the bias 10 ply tires before that I had.

Since I live in a medium size city I use the internet a lot to order goods. Recently I concluded I needed new tires for my 1995 boat trailer I use for my Aluma Craft boat. However popular tire sizes have changed substantially since 1995. I had problems finding the right size for my trailer. Plus I wanted to order rims with the tires so I could install them myself. Fortunately I found etrailer.com which had the right size available at a very reasonable price. I ordered and had my rims and tires within a few days. They are in excellent condition and have been installed. What a pleasant ordering experience. I give etrailer.com an A+ for service, availability, and price!

So far, my wife and I have made 3 trips to Houston, TX from Illinois with the Kenda Karrier tires placed on a camper trailer, this past year. I purchased 2 tires that were delivered free to my home. etrailer was very helpful in selecting the perfect tire mounted on a wheel for my application. Thanks etrailer

Very good customer service. We ordered the wrong tires for our Camper online. I called but the orginal order had already shipped. They were able to get the right tires out and we received both orders the very next day. Took the wrong tires to UPS and shipped them back to them. We were going camping on Friday so having the quick turn around was fantastic. We ordered them on Wednday, received them on Thursday, put them on the camper so we were ready to go on Friday. Great job! We were frantic trieing to find the right tires for out camper and they came through with flying colors. I have told everyone I know that has a trailer or camper about the extra ordinary service.

I was looking for 12" radial wheels and rims for a small trailer. The bias ply tires get hot on the hwy and I did not want to risk a problem. Plus I wanted a spare. I ordered a pair of tires. The online order process is simple and smooth. The shipping was free(I hit a promotion) and the order arrived in 3 days. Very cool. However the box was open when it arrived. This may have occurred from the packaging(simple heavy staples) or it could possibly been opened by driver. Either way I dropped a star. The tires are undameged. I cannot comment on the quality of the product as I have just recieved it.

- AM31199DX

Had the tires arrived filled to the correct air pressure it would have been helpful. Otherwise, excellent in every way. Thank you.

- AM31199DX

Great service. Quick. Excellent tires. Only place I could get 12 inch radial tire and wheel. Looks good as well. Thank you

Nice looking wheels and tires also will see how they hold up on the pop up camper

Easy order, super-quick shipping...only issue was that one of the tires was inflated to OVER 100 PSI; rated for 65 psi.

This wheel assembly arrived one week after I ordered it, which included a 3 day holiday weekend. It came in a sturdy box and was in excellent, new condition. I will not hesitate to order from etrailer again.

- AM31199DX

These work great on a 5X8 open trailer. They are quiet and wear much better than bias ply tires.

Almost 2000 miles on the tires and they still look great.

3+ stars for the Product, 5 for etrailer = 4+ Average. As you probably already know, etrailer is a bastion of information about trailer questions and problems. My original 20.5 x 8 - 10s were always too wide for my 1995 Fleetwood Utah pop-up camper, requiring a crowbar to wedge them back into place between the frame and the 7" electric brake hub. In one section on the etrailer website I found someone who had the same problem, and these wheels were recommended (being narrower by about 2.5"), so I ordered three (one for a spare) after measuring my camper carefully. The wheels arrived promptly. Two had some slight wobble to both the rim and tire (runout), but the third was really bad. (I replaced and checked one of my originals - it also had some slight runout; I guess trailer wheels are not perfect?) I called etrailer customer service to explain my dissatisfaction with the one wheel. The rep (who is evidently learning the trade) was not familiar with the term "runout", and twice had to put me on hold to confer with the techs. When I was told I would be called sometime later in the week by a tech, I was worried, anticipating a long drawn-out return process. However, I was very surprised when I was called by the same rep early the next morning and was told that a new wheel was being shipped to me immediately (even before I shipped my wobbler back), along with a printable call tag via email to ship the wobbler back - all for free! That's customer service! The new one also arrived promptly - it has runout about the same as the other two, so I kept it. Lessons here: research on etrailer to solve your problems; mount your wheels carefully and check them for runout before you tow your rig an inch; use a reputable company like etrailer, so if you have a problem, you have some recourse.

NO problems with the tires. Weve put almost a thousand miles on these wheels and they have performed well. No issues Im a happy camper!

The 2 Kenda Karrier S-trail ST145/R12 Radial Tire w/12" White Spoke Wheel - 5 0n 4-1/2 - LR -D (AM31199DX) tire/wheels were purchased to replace 2 old & worn 6.00-12 tire/wheels on a used boat trailer recently purchased off craigslist. The 2 new tire/wheels were shipped free and arrived within two days of ordering. They were fully inflated and fit the boat trailer perfectly. The new tire/wheels were reasonably priced and the cost free shipping and followup postal tracking and delivery confirmation suggest a very well administered customer service system. Well Done!

The6.00-12 tirewheels are still working well after sitting through a Michigan winter on a boat trailer exposed to snow, rain, etc. Very satisfied with them and again grateful for the free shipping that brought them to me.

I needed to replace my old trailer tires. I wanted tires and rims. I am very pleased I found this item. This has a slightly higher profile than my former tires that were also 12". I had the room in my wheel well. Not problems installing.

Thanks for the great service! The evidently hard to find ST145R12 D tires are on my pop Up. Rims were superior to what I was replacing and what I expected. I'm looking forward to trying out the tires very soon.

I have put over 12,000 miles on these tire and wheels on our camper trailer. Drove on good highways gravel highways and construction highway with lots of bumps. These tire and wheels are great. They have held up better than other brands I have tried.

I was tired of replacing Bias tires on my boat trailer every 2 years. I decided to go with Radials and they made all the difference. After 1 year of use and no signs of wear i am sure i will get more than 2 years out of these tires. Also pulling my trailer with the new tires is a big difference. Trailer tracks truer , less jumping on uneven roads and easier to back. etrailer great place to get your trailer tires.

- AM31199DX

Very impressed with the online ordering process of etrailer.com. The shipping (free over $99) stated 3-5 days ground shipping, however my two (2) trailer tires were at my door by noon the 3rd day after placing the order. Also, the online FAQ section was super helpful. Originally looking for 5.30-12 tire in Radial due to I trailer my marsh boat often. Thru Q&A section of the website, I discovered the ST145/R12 radial tire was comparable and a better option than 5.30-12 bias tires for my needs. They fit great! Looking forward to buy all my trailer tires thru etrailer.com in the future. Thanks again.

- AM31199DX

Found the tires/wheels I wanted in the load range I needed. My local garage couldn't find them.

They are great for my utility trailer. Theyve hauled 40 bags of mulch several times, small loads of gravel and plywood.

    I'll start off by saying that the Kenda KR25 which comes on the # AM31206 and the Kenda S-Trail which is on the # AM31199DX are the same tire; I've linked a photo from the manufacturer that explains this. So what it's going to come down to between these two options is the wheel that they're mounted on. The Kenda Karrier S-Trail # AM31199DX are going to be a more basic, white spoke wheel which is just going to give basic rust protection. The # AM31206 are an aluminum wheel that is going...

    You definitely don't want to use different sized tires because it will cause your trailer to sit uneven and will cause uneven wear both on the tires as well as your trailer suspension and who knows what else.

  • Replacement Wheel Tire for Carlisle 145R12C 95/93L
    To replace your Carlisle 145R12C 95/93L wheel/tire I recommend the Karrier S-Trail ST145/R12 Radial Tire and 5-on-4-1/2 wheel part # AM31199DX. This item consists of a Load Range D tire that is rated to 1220-lbs mounted on a white spoked Dexter wheel with the popular 5-on-4-1/2 bolt pattern. If you need a 4-bolt wheel then instead use # AM35351DX. Both are rated for 65-mph.

  • Do Bearings Need to be Replaced When Upgrading a Tire and Wheel?
    Going with a larger wheel will not affect your bearings at all. However, if the bearings are getting old, it may not be a bad idea to replace them. You will need to remove one of the hubs to gain access to the bearings as you will either need their inner diameters, or their numbers. One thing to keep in mind though, is that the Taskmaster Provider ST175/80R13 Radial Trailer Tire w/ 13" White Mod Wheel # A13RWMQ will have an outer diameter of 24.02 inches and the standard ST145/R12 tire,...

  • Replacement Tires For a Motorcycle Trailer With 12" Wheels and Speed Rating Over 70MPH
    I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10130. This is a radial tire with a speed rating of 81 MPH. The radial tire is much better suited for highway travel as that sounds like what you are using the trailer for. It is a load range D tire with a load capacity of 1,220lbs per tire and fits 12" x 4" wheels. When mounted this tire is 21.3" tall and has a width of 5.7". You will want to ensure that this will fit with the fenders on your motorcycle trailer. You...

  • Does a 5.30x12 Trailer Tire and ST145/R12 Trailer Tire Use the Same Size Wheel
    A 5.30x12 tire like the one in the Kenda 5.30-12 Bias Trailer Tire with 12" White Wheel - 5 on 4-1/2 - Load Range B # AM30740 combo and an ST145/R12 like the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel - 5 on 4-1/2 - LR D # AM31199DX both use 12" x 4" wheels. You could use one of those combos, re-use your old wheels or get some new ones like the Dexstar Steel Mini Mod Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - White Powder Coat # AM20151. I've linked our...

  • Replacement Wheels and Tires for 2005 Forest River Pop Up Camper
    I recommend the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel # AM35351DX as this will be the closest size available for your 2005 Forest River Freedom 1640LTD. It will have the same width as your current tires and is only 1.1" taller. You will want to ensure you have the clearance necessary for the larger tires throughout the suspension travel. I recommend at least 1" clearance on the sidewalls and 3" vertical travel for the tire. The wheel with this tire has a 4...

  • Why Can't 13 Inch Wheels Fit Trailer Hubs Designed for 12 Inch Wheels
    The issue with using a 13 inch wheel on the Dexter Trailer Hub and Drum Assembly for 2,000-lb E-Z Lube Axles # 8-257-5UC3-EZ, which you correctly noted is for 8 inch to 12 inch wheels, is that hubs of that size do not have a large enough flange diameter in order to to provide the necessary side-to-side support for a larger 13 inch wheel. Technically it may fit but it would not be recommended. The best option is to go with smaller 12 inch wheels and tires. For a 5 on 4-1/2" bolt pattern,...

  • Upgraded Wheels/Tire for Keystone Camplite with 205/65-10 Tires
    I recommend using the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel part # AM35351DX for 4 bolt or part # AM31199DX for 5 bolt to replace the 205/65-10 tires on a Keystone Camplite. This new wheel/tire combo should just bolt onto the existing hub. They are slightly larger in diameter but narrower in width. This will give you better ground clearance and they are a radial ply so they will run cooler out on the highway which further reduces the chance of a blowout. They...

  • Recommended ST145/R12 Tire with Steel Wheels or Aluminum Wheel with Higher Load Rating
    That particular tire size we only have available in one wheel choice and it is the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" Aluminum Wheel - 5 on 4-1/2 - Load Range E # AM31215. This is because we didn't want to limit the load capacity of the tire. We do have the tire available separately so it can be put on a steel wheel. It is the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range E # AM10140, but your weight capacity will be limited by the steel wheel....

  • Is Larger Load Range Tire Okay for 1992 Coleman Trailer
    Yes, you can use a larger load range tire, like a load range E tire on your 1992 Coleman trailer, so long as the tire fits your current wheel and you have enough clearance (3" from the top of the tire to the fender and 1" from the inside of the tire to your frame rail). For example, if you have 12" wheels and your trailer uses ST145/12 tires, you can swap to the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range E # AM10140. If you don't have 12" wheels you will also...

  • Options To Gain More Tire To Frame Clearance On Trailer With ST175/80R13 Tires
    I have another option for you, but we do not have any 13" trailer wheels with offset to push the tire further from the frame, and do not recommend using any spacers as they can cause additional stress on the hubs which can wear out bearings and the tire prematurely. There are two options to fix the rubbing issue. Option one is replacing your wheels and tires with the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel - 5 on 4-1/2 - LR D # AM31199DX which has the...
