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"

Average Customer Rating:  4.9 out of 5 stars   (254 Customer Reviews)

Radial tire has a ply rating of 8 and a 1,220-lb maximum load at 65 psi. The 12" diameter x 4" wide aluminum trailer wheel features a 5 on 4-1/2 bolt pattern and is corrosion resistant.

They are aluminum wheels and seem to be well-made. Here is a hint, though. The holes are too small for the two automotive lug wrenches I tried. I tried a 13/16" Spark Plug socket but it was too weak and deformed (if you try that and don't deform it you may not be putting enough torque on it). I bought a 13/16", 6-Point, 3/8" Drive Socket from Sears which works fine. 220327

I had a flat on my boat trailer returning home from a Minnesota walleye fishing trip. A few of the guys I was fishing with told me about E Trailer and how great they were so I called them to order this new tire & rim combo. The product shipped the day I ordered it and arrived the next morning via UPS. I was able to mount the new tire & rim, seems to fit well only problem is that I don't have correct lug bolts which I ordered and those shipped same day and are delivering next day. Overall I would highly recommend this company, the people are really friendly, helpful if you aren't 100% sure of exactly what you need. Heidi, Judy and Kevin all helped me with my orders and they were really great folks. I'm ordering rest of my boat trailer tires from this company from now on. 567327

I have had a great experience with these tires and rims. I put them on my utility trailer and they not only look great, but they handle the loads I carry. I haul a large lawn tractor, crush and run gravel, tree limbs and other such materials as need and the tires just keep doing their job. I recommend these tire/rim combo for OEM replacements, you won't be disappointed. 245983

Review from a similar Karrier Aluminum in Trailer Tires and Wheels


The wheel and tire combo arrived quickly and the quality looks excellent. The finish on the wheel was smooth and had no scratches. It SHOULD be mentioned in the description of wheel that a very long lug nut is required. I had ordered the AM90054 nut not knowing the rim would need the AM90070 nut. Now paying extra for the purchase and shipping of the longer nut. 46978

  • Aluminum 12" Wheel and Tire Recommendation for Highway Speeds of 75 mph
    If you really like the Aluminum Hi-Spec Series 04 Star Mag Trailer Wheel # AM20163 that comes with the Kenda # AM31206 then all you would need is the Taskmaster 5.30R12 Radial Trailer Tire # TT53012C and the valve stem # AM20907. The tire has a load range of C (1,050 lbs at 80 psi) and is rated for 81 mph so it would be perfect for cruising at 75 mph. Unfortunately we do not have any tires pre mounted on a 12" wheel that have a speed rating over 65 mph. After getting these parts you...

  • Difference Between Kenda Karrier K25 Vs S-Trail Trailer Tire

I have attached a photo from the manufacturers website to hope clarify this for you. The Kenda KR25 ST145R12 Radial Trailer Tire with 12" Aluminum Wheel part # AM31206 that you were looking at is an excellent option.

  • Recommended Replacement Tire & Wheel for Motorcycle Trailer
    Unless otherwise noted all trailer tires are only rated for up to 65 miles per hour. Going faster than that causes heat to build up which then causes the tires to fail. For a white wheel and tire that would work as a replacement and would match your current size you would want the part # AM30060. This setup would have a maximum capacity of 760 lbs per tire at 90 psi. With trailer tires you want to have them inflated to their max PSI at all times. Any less pressure will cause the capacity...

  • Are Radial Tires Better than Bias-Ply Tires for a Boat Trailer
    Due to it's construction, a radial tire has more flex and will allow for more ground contact which improves tractions and tread wear. It also gives the radial tire better stability and will normally run cooler which will help the tire last longer, especially when the tire is under a load. When it comes to radial tires and wheels for your boat trailer, I recommend Kenda KR25 ST145R12 Radial Trailer Tire with 12" Aluminum Wheel, # AM31206. This tire has a section width of 5.7 inches and...

  • Will Kenda KR25 ST145R12 Radial Trailer Tire Replace a 5.30x12 Trailer Tire
    First, we do have 5.30x12 tire and wheel combos with a 5 on 4-1/2 bolt pattern available. For a load range D it would be # AM30859. This tire and wheel combo is rated for 1,250 pounds at 105 psi. It includes a white steel wheel. The Kenda KR25 ST145R12 Radial Trailer Tire, # AM31206, with aluminum wheel is only 0.1 inches wider and 0.6 inches shorter so it will most likely fit. It is rated for 1,220 pounds at 65 psi. I have included links to tire and wheel FAQ articles for you.

  • Can Tire Pressure Be Lowered On Small Utility Trailer
    It is always recommended to inflate the tires on a trailer to the maximum pressure. If you do not inflate the tire to its maximum, it reduces the amount of weight a tire can carry and if overloaded can cause the sidewalls of the tire to overheat and fail. If you over inflate the tires it will cause tread wear at the center of the tread and if under inflated it will wear the outside edges of the tire. It's always recommended to inflate the tires when they are cold. I have attached...

  • Comparing Trailer Tire Sizes 20.5x8-10 and 145/80-12 for a Snowmobile Trailer
    First, you want to use the tire size and load range specified by the trailer manufacturer as it has been deemed the best option for that particular trailer. Sometimes you can go to a different tire size provided there is enough space around the existing tire for a larger size or if the capacity of a smaller size is sufficient for the gross trailer weight capacity. The 20.5x8-10 is an older tire size designation that isn't really seen on trailers anymore. It has been replaced with the...

  • Comparing 5.30-12 and 205/65-10 Trailer Tires
    There are differences between the 5.30-12 tires and 205/65-10 tires. The 205s only fit a 6 inch wide wheel so you would have to replace the wheels as well if you make the switch. A 205 will be 20.5 inches tall whereas a 5.30 will be 21.9 inches tall. The 205s will also be 8.3 inches wide. A 5.30 will be 5.6 inches wide. This is a big difference and you would have to have at least 1-3/8 inches of clearance between the existing tires and the nearest part of the trailer for the larger...

  • Need Larger Tires and Rims to Replace the Ones on my Karavan Jetski Trailer
    If you are looking to stay with a 12 inch wheel, I recommend going with the Kenda KR25 ST145R12 Radial Trailer Tire with 12" Aluminum Wheel, # AM31206. This tire measures in at 5.7 inches wide which is approximately 1 inch wider than the other tires that we offer for 12 inch rims . For a tire and wheel combo that is substantially wider, the Kenda 205/65-10 Bias Trailer Tire with 10" Galvanized Wheel, # AM3H400, may work for you. This tire measures in at 8.3 inches wide.

  • Is Wheel Pilot Hole Diameter Important When Selecting New Wheels for Pop-Up Camper
    It is ideal to match up the pilot hole size of wheels with your existing hubs since the actual weight load on the wheel is intended to be supported both at the pilot hole and studs, and not just at the studs themselves. If the wheel's pilot hole is much larger than the hub requires then the full load on the wheel will be carried on the studs. All of the 12-inch wheels with 5-on-4-1/2-inch bolt pattern that we offer (please see included link)have a 3.19-inch pilot hole diameter. Smaller...

  • Replacement Tire/Wheel Combo Recommendation for 20.5x8x10 Tires on 1991 Coleman Shenandoah
    Your current 20.5x8x10 size tire is equivalent to the current tire size of 205/65-10 which has an overall diameter of 20.5" and a rim width of 6". Since your wheel has a 5 bolt pattern it should be the 5 on 4-1/2" bolt pattern which is the most common. I took a look at the specs for your 1991 Coleman Shenandoah and it looks like this pop up camper came with a 2,000 lb axle. With that being said, I recommend going with the Kenda KR25 ST145R12 Radial Trailer Tire with 12" Aluminum Wheel...

    The trailer tire and wheel combos, like the Kenda KR25 ST145R12 Radial Trailer Tire with 12 Inch Aluminum Wheel, # AM31206, that you have referenced, do not come with lug nuts or center caps. If you look on the right side of the product page, you will see a list of related products that includes compatible lug nuts and center caps if available.

  • Are Trailer Tires that are 7 Years Old and Inflated to Half Max Pressure Rating Safe to Use
    We don't recommend using trailer tires that are over 6 years old as they are much prone to failure. The tread may look fine but the tire overall is most likely dry rotting and beginning to lose it's integrity. Also, we have to recommend you run the tires at max tire pressure at all times. Failure to do so will cause heat to build up due to too much sidewall flex/heat which will also cause premature failure. Basically running a 6 year old trailer tire at half the max pressure rating is a...

  • Troubleshooting Lug Nuts or Wheel Bolts Not Threading On To Hub With Kenda Tire and Wheel # AM31206
    The Kenda KR25 Tire and Wheel, # AM31206, is designed to work with bulge style lug nuts 1/2 inch - 20 threads per inch like part # AM90054. The bolt holes on the wheel will have a 60 degree angle that this lug nut will fit into to tighten onto the wheel stud. If you are using a lug nut similar to part # CE11051, we have experienced problems with this style of nut not fully threading onto the stud because there is not a bulge seat at the 60 degree angle and the hex portion begins to...

    The Load Range E of the tire size 205/65-10 that you referenced has a 1,650 lb capacity when inflated to 90 psi. The only way we can safely recommend you run this tire is at it's max capacity. Otherwise the capacity would be diminished (to an unknown amount), and the tire would heat up and potentially fail.

  • Does the Pilot Diameter of Replacement Wheel Need to Match Existing Wheel
    There are two types of ways a wheel interfaces with the hub. This junction can be considered hub centric or lug centric. If your current wheels attach to the hubs using lug nuts where the wheel slips over the wheel studs, they're considered lug centric. In that case the pilot diameter size of the wheel doesn't matter, as the wheel studs themselves support the wheel. As long as the pilot diameter is large enough that the dust cover that covers the bearings can pass through the pilot opening,...

  • 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...

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...
