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.

Radial Tires vs. Bias Ply Tires

The cords on this radial ply 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, which leads to a longer tread life and improved steering.

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"

Video Transcript for Kenda Tires and Wheels - Tire with Wheel - AM31215 Review

Today we'll be reviewing part number AM31215. This is the Kenda ST145R12 radial trailer tire with a 12" aluminum wheel. The special trailer tire design is going to couple the strength of a bias tire with the durability and stability of a radial tire. It is created specifically for trailers, so it's not intended for use on other types of vehicles. It's going to feature the double steel belts and full nylon plys that are going to combine for superior function and long life. It's also going to feature the computer-generated tread design and premium rubber compound materials that are going to offer superior traction in wet or dry conditions. The aluminum wheel is by Americana.

It's going to be very durable and rust-proof, featuring an attractive star spoke pattern. The tire and wheel assembly meets Department of Transportation specifications. Now when it comes to the rim dimensions it's going to give us a diameter of 12", with a width of 4". The bolt pattern's going to be 5 on 4-1/2 so that means that we're going to have 5 bolt holes. The distance measuring from the center of one bolt hole directly across to the area between the two bolt holes on the other side at a straight line measurement is going to measure 4-1/2", so 5 on 4-1/2".

The lug size is 1/2". The pilot diameter is going to measure 3.19". That's measuring the diameter of the larger hole here at the center of the wheel. Now the wheel's going to offer a capacity of 1,520 pounds. The tire size is ST145R12. It's going to give us a section width from edge to edge of 5.7" and an outer diameter of edge to edge right at 21.3".

It's going to feature a load range of E with a 10-ply rating. Maximum load of the tire is 1,520 pounds at 80 psi. It does have a maximum speed rating of 65 miles per hour. It's going to feature all the indicators listed here on the outer wall of the tire. That way you can always use that as a quick reference guide if you ever need any of that information. That's going to do it for today's review of part number AM31215.

This is the Kenda radial trailer tire with a 12" aluminum wheel. .

Great tire and rims look good too. Use them for mostly short local fishing trips but used them a 1,000 mile round trip to Canada this past summer. Much better and smoother ride than the factory bias ply tires. Looking for something reliable give these a shot. Spend a little extra money you won't be disappointed. Picture is right after installation 356573

Wanted to let you know the tires arrived today. They look great. The only issue is that the holes around the lug nuts are not large enough to allow a 13/16 impact socket to pass through. Standard lug nuts are too shallow. I suggest you suggest to buyers they purchase a set of chrome lug nuts that are long enough to protrude 3/4 inches past the hole so a socket can easily be connected. Attached is a photo of the lug nuts as well as a shot of my finished Acme Tow Dolly trailer. Thanks again for the speedy shipment. 485295

Found a cut in an existing acme tow dolly tire originally ordered from etrailer.com. Ordered a replacement with my phone the afternoon I discovered the cut. It was shipped free that day.

The wheels look great on my aluminum utility trailer. They've only been on for a week, so I can't say a lot about the tires. etrailer is an awesome retailer, and their prices seem to be very competitive. 502870

The tires and wheels are great. They replaced a set of low speed tires on a aluminum trailer I bought from [local discount tool store]They still look like new. Thank you for checking in. I always refer your company when others ask about tires and wheels or other parts you may carry.

  • How to Get the Most Out of Your Trailer Tires
    We have just what you are looking for. Although we do have load range D tires in the 5.30-12 size they are bias as opposed to radial in style. Bias tires are meant more for off-road purposes like agriculture whereas the radial tires have a sidewall with more flex that can better dissipate the heat build-up than bias can. I recommend going with the Taskmaster 5.30R12 Radial Trailer Tire # TT53012C. It has a load range of C (Maximum load: 1,050 lbs at 80 psi), a max speed rating of 81...

  • Replacement ST145R12 Tire and Wheel for Acme Tow Dolly
    Any trailer or tow dolly tire should always be inflated to the maximum psi pressure shown on the tire sidewall. It is never appropriate to under- or over-inflate a trailer/dolly tire since only when fully inflated can the tire deliver its rated weight capacity. Naturally it is also important that the vehicle loaded on the dolly be within the dolly's rated capacity. Acme offers several different dolly products and these are specified to use Load Range E tires in size ST145R12. Their...

  • Replacement ST145/80-12 Tires for 2003 Rockwood Freedom M-1910 Camper Trailer
    Based on my research I believe the tire size on your 2003 Rockwood Freedom Model M-1910 camping trailer is actually ST145/80-12. Online specs for the M-1910 indicate a dry weight of 1719-lbs so your estimated GVWR of 2323-lb sounds about right. Still, I suggest checking the trailer's main identification plate (which has its VIN) to find the GVWR, which is the most it can safely weigh when fully loaded. Once you have confirmed the trailer's GVWR it is simply a matter of dividing that...

  • Recommended Wheel For Trailer W/12 inch x 4 inch 5 on 4-1/2 Bolt Pattern
    Since 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...

  • Trouble Removing Lug Nuts on the Kenda Karrier S-Trail w/ 12" Aluminum Wheel # AM31215
    Thank you for the picture! The problem you are running into has more to do with the lug nuts you are using than the tire wrenches like part # PTW1 that you referenced. Since the Kenda Karrier S-Trail # AM31215 is a little more recessed where the lug nuts sit you need to swap out your shorter lug nuts, like part # CE11051, and replace them with taller lug nuts like part # 12CLN. Changing out the lug nuts to taller ones will allow you to easily fit a lug wrench over the lug nuts so you...

    You didn't mention what size tire you have, but the part # AM31215 that you mentioned is a 12 inch wheel and tire combo with a 5 on 4-1/2 inch bolt pattern. So for a similar setup with an 81 mph speed rating we have the # AT53012R45SM which is a 5.30-12 size tire on a wheel with a 5 on 4-1/2 inch bolt pattern.

We do have tires with higher speed ratings, but they do not come with a load range E so if that is more important to you than speed you will want to stick with the Kenda Karrier S-Trail.

  • Radial Tire Recommendation to Replace 20.5x8x10 Tire
    If you are dead set on getting a radial tire you would need to go to at least the 12 inch wheel size 145R12 like the part # AM10130 which is a radial. If you wanted to go with a wheel and tire combo we have the part # AM31215 which has a 5 on 4-1/2 inch bolt pattern or part # AM31208 which has a 4 on 4 inch bolt pattern. Overall tire diameter would increase about an inch.

  • Should I Switch To Radial Tires From Bias On Boat Trailer That Travels On Highway
    I definitely recommend to switch over from bias tire part # AM1HP52 to radials if you are traveling on a hot Florida Highway. Radial tires cords are positioned to flex easier than the stiffer sidewall of the bias tires. Bias tires create more friction while going down the highway because of their stiffer sidewall which creates heat and can lead to blow outs. I recommend the Kenda Karrier S-Trail part # AM10130 which is a ST145/R12. The diameter of the tire is only 1.3" larger than...

The other places must have only had a limited selection because you can get a 145/80-12 with a capacity as high as 1,520 pounds. If the trailer has a 4 on 4 bolt pattern, see link on how to determine bolt pattern, then you can use tire and wheel combo # AM31208.

    Trailer wheel/tire items such as Kenda Karrier S-Trail ST145/R12 # AM31215 are not given a full dynamic balancing treatment but they are mounted together so that the tire's light spot is mated to the wheel's heavy spot. This provides enough balancing for trailer tires. Passenger vehicle tires on the other hand require a full dynamic balance (with weights added as needed) so that they perform properly. Trailer tires can be balanced in this way if you like but it is not essential.

    Backspacing is measured from the hub's mounting surface to the inside lip of the wheel. If you switched from a 4-1/4" backspacing to a 3-1/2" backspacing, the wheel would stick out away from the trailer more. Therefore, you won't have any issues with rubbing the inside frame rail which means you shouldn't have any issues with overall fit.

  • Can Smaller Wheels be Used on Boat Trailer if Wheel Bolt Pattern is the Same?
    Yes, you can use smaller wheels as long as they have the same bolt pattern, but you do need to ensure the tires have a load capacity which is high enough for your boat and trailer. The most common bolt pattern is 5 on 4-1/2" so that is likely what yours is, though you want to verify this by measuring; if you are unsure of how to do this I've added a help article which details exactly how you can find out.

  • Can F65-14ST Tires be Replaced With Smaller Diameter Tire?
    The F65-14ST tires you have are 24.49" in diameter and 8.07" wide and are similar in size to ST205/65-14 tires. There are not going to be trailer tires that you can get which are going to fit 14" wheels and have a smaller diameter so what you are going to need to do is change to smaller wheels. I recommend 12" wheels and the Kenda Karrier # AM31215 will give you a 12" wheel with a 5 on 4-1/2" bolt pattern along with ST145/R12 tires that have a 21.3" diameter, are 5.7" wide and have...

  • Replacement Tires and Wheels For 2016 Jayco Pop-up Camper 12UD
    Great News, The ST145/R12 tire size does come in a load range E already assembled to the wheel with part # AM31215. We normally do not recommend going down in load ranges from what the manufacturer put on the trailer but if the tire is properly rated for the weight of your Jayco then it shouldn't be a problem if you choose to do so.

  • Special Trailer Tire to Replace Size 155R12 on Pontoon Boat Trailer
    The width of a 155/12 tire is just over 6-inches. The closest match in a special trailer tire size is a 145/12 at 5.7-inches wide. I have included a link to all of the tires and tire/wheel combos we have in this size and with a 5-on-4-1/2 wheel lug pattern. We have this tire size in two Load Range ratings, most in LR D and one, # AM31215, in a higher-capacity LR E.
