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"

  • Can 10 Inch Wheels be Replaced by 12 Inch Wheels on Trailer
    You are smart to move to radial tires and you do not need to make any axle modifications on your trailer you only need to know your wheel's bolt pattern; if it is 4 on 4" or 5 on 4-1/2" you can simply replace your wheels with new 12" wheels. If you are unsure of what your bolt pattern is please take a look at the help article I have added which explains how to determine the bolt pattern of a trailer wheel. Keep in mind you also need to know your Coleman Sequoia's GVWR to get the proper...

  • Can I Swap Out My Tires On My EZE Tow Dolly to a Larger Size?
    Hello Eric, I would definitely be looking for new tires as well, sounds like the tire you mentioned is on the verge of a blow out from sitting too much. You can most likely swap out the tires on your EZE Tow Dolly for a larger size, you will need to make sure that you have the clearance though. The Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel - 5 on 4-1/2 - LR D # AM31199DX is going to have a total width of 5.7", and an outer diameter of 21.3". I would go out and...

  • Trailer Tire that is Wider than 4.80-12
    For a slightly wider wheel and tire setup you'd want the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel # AM31199DX which fits the 5 lug pattern you have. The has a section width of 5.7 inch which is going to be about an inch wider than what you have.

  • What is the Difference Between the Kenda S-Trail and Kenda KR25
    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. An aluminum wheel that is going to provide you with the best rust protection possible, so I recommend going with those since they're going to provide you with a much more long-lasting wheel that won't rust out.

  • 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"...

  • Closest 12" Trailer Tire and 5 Lug Wheel to Replace ST155/80D13 Tire and Wheel.
    You'll want to go with the Kenda ST145/80R12 # AM31199DX for a white wheel or # AM35354 for a black wheel. Both of these options have the 5 on 4-1/2" bolt pattern you're needing. This will be the closest option to your current ST155/80D13 tire size coming at 1" shorter overall and 3/4" narrower so you'll have zero clearance issues.

This is a smaller rim but the overall dimensions will be good for your trailer. If you want the same size wheel then I recommend the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel - 5 on 4-1/2 - LR D # AM31199DX....

  • 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.

  • Recommended Trailer Tires Size 5.70 x 8 for Highway Speeds
    The only 5.70 x 8 sized tire we carry that is a Load Range D is the Kenda K353 # AM10013. 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 for...

  • 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 Provider ST175/80R13 Radial Trailer Tire w/ 13" White Wheel # TA43RR will have an outer diameter of 24.02 inches and the standard ST145/R12 tire, like the # AM31199DX,...

  • 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,...

  • Upgrading the Tire and Wheel on a Harbor Freight Trailer
    From what I could find, the Harbor Freight trailers do say not to exceed 45 miles per hour in the owners manual. That being said, the tires they use are not rated very high and may be the limiting factor. The trailer you have looks to use a 5 on 4 1/2 bolt pattern and 12 inch wheels. I definitely suggest upgrading what you have to the Kenda Karrier S-Trail ST145/R12 # AM31199DX. This, as with all 12 inch tires, will be limited to 65 miles per hour, but this is also rated up to 1,220 pounds...

  • How Much Taller is a ST145/R12 Radial Tire Than a 4.80 x 12 Tire?
    The Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel - 5 on 4-1/2 - LR D item # AM31199DX would be a great replacement tire for your utility trailer. The 4.80 x 12 tires you already have give you an overall diameter of 20.7" and width of 4.9". The Kenda tires are 21.3" tall and 5.7" wide. So you are looking at just over a 1/2" taller at .6" and almost an 1" wider at .8". They recommend a minimum 3" of clearance between the fender and the top of your tire and 1" clearance...

  • Will 145/80-12 Radial Tires Replace 5.30-12 Bias Tires
    Your current 5.30-12 tires fit the same size wheel as a 125/80-12 tire so this is a fine replacement. They both fit a 4 inch wide wheel and you're actually going down in diameter by about a 1/2 inch and the width is basically the same so there won't be any issues with clearance. A good tire to use as a replaecment is part # AM10130 which is a load range D with a max capacity of 1,220 pounds at 65 psi. I don't know what bolt pattern your wheels are or what they look like but optoins for...

  • Recommend Upgrade for 20.5x8-10 Trailer Tires
    The next size up from a 10" wheel would be a 12" wheel, the closest to a 20.5x8-10 tire would be a 145/80-12. For this, I recommend the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel part # AM31199DX which is a pre-mounted combo that comes with a radial ply tire and powder coated white steel wheel.

  • Upgrading Axles from 2,200 lbs to 3,500 lbs to Utilize 10 Inch Electric Brake Assemblies
    The 4 hole brake mounting flange will work for 10 inch brakes because the 7 inch and 10 inch assemblies use the same 2-7/8 inch on center mounting holes. The brake assemblies like # AKEBRK-35 or self-adjusting assemblies like # AKEBRK-35-SA will both fit 10 x 2-1/4 inch hubs. The issue you will find is with the 2,200 lb spindles because you won't find the 10 inch hubs compatible, so you will need to upgrade your axles as you stated to the 3,500 lbs axles.

The Kenda S-Trail ST145R12 Radial Trailer Tire with 12" Aluminum Wheel - 5 on 4-1/2 - Load Range D # AM31202 probably came from a different location of manufacture that either doesn't stamp them the same or has not been updated yet.

  • Is There an Option for a 12 Wheel With 5 on 4.75 Bolt Pattern?
    The 5 on 4 3/4 bolt pattern is starting to get less and less common, so they are getting a little difficult to find. With that being said, this bolt pattern was generally not used on wheels of this size in the trailer world. If you take a look at the Dexter Trailer Idler Hub Assembly for 3,500-lb Axles - 5 on 4-3/4 # 845475UC1, it will only fit wheels from 13 inches to 15 inches in diameter. This has to do with how a hub will sit inside a wheel and, unfortunately, 12 inch wheels do not...

  • How To Determine Proper Load Range Capacity for Trailer Tire
    In order to determine the correct load range capacity for tires on your trailer you need to get a tire that exceeds the GVWR of your trailer. You mentioned the trailer spec was 2,090 and that may be the GVWR, especially if the axle was a 2,000 lb axle (though that would still be underrated). In regards to your mechanic saying only a 5,30-12 tire would fit, there are similar size tires so that would not be the case, although he may have been talking about the wheel, because a wheel only...

  • 2010 Flagstaff 176LTD Tire and Wheel Upgrade with Higher Speed Rating
    Since you have the clearance for the larger tire I'd go with the Provider # TA43RR that you mentioned as it has the higher speed rating you want at 81 mph, has a higher weight capacity, and requires 50 psi as opposed to 65 psi like the other tire you mentioned which will be easier to inflate to. Larger tires in general are easier on hubs and trailer suspension since the wheel ends up spinning slower and the bumps aren't felt as severely. Worth mentioning is that typically tire failure...

  • Can You Use a 4.80x12 Trailer Tire As a Spare for 145/12 Trailer Tire
    I can't recommend using different size tires on a trailer, even for short distances. That said, a 145/12 tire measures 21.3" diameter x 5.7" wide and a 4.80x12 tire measures 20.6" diameter x 4.8" wide. Therefore, there's only a difference of .7" diameter and .9" width. If I were you, I would probably just use the smaller size as a spare until I could get the trailer into a shop for the correct size. That said, I also can't really officially recommend this.
