Karrier S-Trail Radials with Automotive-Grade 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
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 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.
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.)
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.)
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"

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! 433153

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.

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. 713337

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. 445504

Great product, looked everywhere locally with no luck until I called etrailer. Spoke to a great representative who assisted throughout the process and found the right tire and rim color. She actually found what I was looking for, which was not readily found on the website. Very happy! Highly recommended, especially the representative of the company.

This is an excellent tire/wheel combo for the price. The tires arrived inflated and ready to go. I only have about 1000 miles on them, but they seem to be wearing well. The tires also held air for the entire year, and only required a small topping off once. They might have lost 3 or 4 psi. 762211

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! 651718

If you are open to changing your wheels and your tires then the change is possible.

view full answer... - Replacement Wheel and Tire for Size 145R12 on 5 on 4-1/2 inch Bolt PatternIf you measure the outside of a trailer rim the overall diameter won't necessarily match the size. That's because of the mounting lip. But since we know your tire size is 145R12 we know you have a 12 inch rim. For a replacement wheel and tire in that size the part # AM31199DX would be a great option.

- Recommended 145/80-12 Radial Tire and Wheel to Replace Bias Tires on 5 x 8 Utility TrailerThe Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel # AM31199DX is the correct model to look at to replace your current Kenda # AM30820. Switching to radial tires is also a very good idea since you are driving on the highway for longer periods of time. The reason for this is radial tires flex a bit more than bias tires as well as run cooler under a load, allowing them to last longer and withstand highway driving. As for the tires, the 145/80-12 tires on the Kenda...

Trailer tires are typically less expensive than automotive tires because they do not have to meet the same safety standards since they are not designed for use on a vehicle transporting people.

So what it's going to come down to between these two options is the wheel that they're mounted on.

- Recommendation to Replace ST145/70R12 TiresYou 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. I really wouldn't advise using that as a spare unless you are only going to be traveling a very short distance for repairs (like within a mile).

- Determining Correct Tire and Wheel Size for Trailer with 2,000 Pound Axle There is not a specific tire/wheel size that is recommended for your trailer, although you are likely limited to a maximum 12 inch wheel size with the hubs for its 2,000 pound axle. I recommend taking a look at the tire size you currently have mounted, which will be located on the sidewall of the tire itself. If there are no tires or wheels present, you can also look for a sticker or plate somewhere on the trailer that might indicate the recommended tire size. Otherwise, you will just...

- 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.

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.

It's a bias tire with a maximum capacity of 1,075 at 100 psi. The maximum speed rating on this tire is 65 mph. I don't know what your current tires are rated for but they might say somewhere on the tire's sidewall. You will want to stay within the speed rating. Exceeding it will cause the tire to heat up more than it should which can cause the tire to fail. Radial tires are generally better...
view full answer... - Recommended Wheel For Trailer W/12 inch x 4 inch 5 on 4-1/2 Bolt PatternSince we do not carry any radial tires that are size 5.30-12, the next closest option is a 145/80-12 sized tire. The new tire is about 1/2 inch smaller so it will work great for you. Radial tires are a good choice because they flex more than a bias tire which gives better ground contact, traction, stability, and tread wear. Radial tires generally run cooler than bias tires as well which usually leads to a longer tire life. With your wheel size, you have several options. I recommend the...
view full answer... - Smallest Radial Tire For A Snowmobile Trailer ApplicationThe smallest radial tire we have is a 12 inch tire. I've done the calculations with the tire on a 12 inch rim and you'd be looking at a little over 21 inches diameter with # AM31199DX. The load rating would right around 1220 at 65 psi with a load rating of D. You would be limited by your axle and not the tire if you are able to fit this large a tire when loaded. The radial tires will run cooler on your long drives.
view full answer... - Replacement Wheel and Tire to Replace 14.5x7 Tire SizeProbably the best option we would have would be to replace the wheel and tire together. The closest overall diameter wheel and tire we have would be the size 145/80-12 which is overall 21.3 inches. If you need a 4 on 4 inch bolt pattern you would need the part # AM35351DX or for 5 on 4-1/2 inch bolt pattern the part # AM31199DX.
view full answer... - Kenda Karrier S-Trail ST155/R12 Compatibility With 12x4.5 Inch WheelI reached out to the manufacturer and the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range E # AM10140 will fit a 4.5 inch wide rim, however it may change the load capacity as the tire may be stronger than the wheel. If you have a heavy load you are carrying, you may want to have a 12x4 inch rim. We do have some pre-mounted options for that tire: Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" Aluminum Wheel - 5 on 4-1/2 - Load Range E # AM31215 Kenda Karrier...
view full answer... - Replacement Tire and Wheels For Size 6.00-12I do have some options for you. The closest tires and wheels that compare to the one pictured are our 145/80-12s. I recommend using either the Kenda Karrier S-Trail # AM31199DX, or the Kenda Karrier Black Mod # AM35354; both of these tires have a 1,220 lbs maximum load at 65 psi. I am recommending the tires with the wheels because even though your wheel might be functional, it looks like it is a little beat up around the edges. Keep in mind that you will want to verify that these tires...
view full answer... - Can You Upgrade From 18x8.50-8 Tires to 145/R12 Tires on 1976 Jayco Tent Trailer?You may be able to go from a 18x8.50-8 tire to a 145/R12 tire so long as the wheel has the same bolt pattern and you have enough clearance from the fender to the top of the tire; we generally recommend at least 3 inches of clearance from the top of the tire to the fender. We have 145/R12 tire and wheel combinations that may work for you. The Kenda Karrier S-Trail # AM35351DX has a wheel with a 4 on 4" bolt pattern and the Kenda Karrier S-Trail # AM31199DX has a wheel with a 5 on 4-1/2"...
