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"

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

I purchased the Karrier Aluminum wheel & Kenda tire package as a spare for my Trillium 1300. It appears to be of good quality, the price was competitive and the wheel and tire arrived promptly. I fortunately have not had to use the spare yet, but if and when I do, I am sure that it will perform as required. 442773

This spare tire and wheel is a great product at a competitive price and although I have not had a chance to use it, I am sure that it will fit the purpose just fine.

I recently ordered this wheel/tire combo to spruce up my Coleman Fleetwood Mesa popup camper. They look great and the fitment is superb. I ordered 10 AM90070 lug nuts (which are needed) and some center caps LHCS102 to help complete the look and finish. Unfortunately the center caps didn't have the snap-in plugs which are supposed to be included, but I've contacted etrailer and I'm sure they'll get me some. 718067

Buying tires from etrailer was great, everything went smooth and the price was right. Iā€™m glad I read reviews because I needed longer lug bolts for my new rims. Thank you etrailer 613472

Got what I ordered and when I was suppose to get it. Great service. 574995

I recently replace galvanized rims and tires on my boat trailer with the Karrier radial tires and aluminum 5 spoke wheel. I also purchased the stainless lugs and stainless center hub to complete the look! The items were shipped in sturdy protective boxes that held 2 tires each, and the products were flawless and very good quality. The other reason for the change, is when launching a boat in salt water, this product will protect your studs, hubs and resist the rust that occurs very quickly in this environment, it also protects barren cap lubrication area. I would highly recommend etrailer.com. great website and very knowledgeable staff. 562199

Review from a similar Karrier Aluminum in Trailer Tires and Wheels

After asking all local tire shops about Load D 13" tires and being told they don't have and can't get. I looked them up online and found them here and purchased them. Etrailer.com upgraded my shipping for free and I had them at my door in 2 days! I got them installed and they look and ride great! And the price was way better than I thought it was going to be, Thanks Etrailer.com I will reccomend your site to everyone! Chris W. 43324

Review from a similar Karrier Aluminum in Trailer Tires and Wheels

First off what can i say, Kudos to George and staff. The tires and rims that i order are not like the photo. They look a lot BETTER. They ride great on my boat trailer. I have a 2010 avalanche with the 5 spoke polished aluminium rims, almost a perfect match. I received them in an expeditious manner. I Also purchased the matching chrome lugs nuts. I am also going to get the chrome Bearings Buddy Bearing Protectors. Received a lot of complement from friends and neighbors who saw the old white rims, and they really like the new ones. First thing they say is that they match the truck rims (Ya) (Boat is white with gray silver metallic trim) Perfect match. ENOUGH SAID ....... 471440

Review from a similar Karrier Aluminum in Trailer Tires and Wheels

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.

  • Is Trailer Tire and Wheel # AM31959 Balanced
    The tire and wheel combos we carry like # AM31959 are not machined balanced. You can have the tire and wheel combos balanced at a local tire shop if you wanted to. What our tire manufacturers will do is line up the light spot on the tire with the heavy spot on the wheel. This is a type of balancing but not like how car tires are balanced (with weights on a balancing machine).

  • Would Karrier ST175/80R13 Radial Trailer Tire AM31959 Fit 2016 Little Guy [email protected] T A G camper
    Most likely yes it will, but I'd need to know the bolt pattern of your current hubs. Can you count the lugs for me? Also what size tire do you currently have? If it's a 5 lug wheel with a ST175/80R13 tire installed on it the part # AM31959 would fit and work well.

    If your 1983 Calkins boat trailer is rated for 2,375 lbs GVWR (Gross Vehicle Weight Rating) then the Loadstar ST175/80D13 Bias Trailer Tire # AM3S140, which has a load range C (1,360 lbs at 50 psi), will be able to handle the weight. I am not sure how much your whole setup weighs so it might be best to take it by a weigh station just to be sure you know how much it all weighs.

  • Comparing Loadstar, Karrier, and Westlake ST175/80-13 Tires
    I'm not quite sure why it's called a "rating" column because that just has to do with how many reviews have been left on the product page. The biggest differences between the Loadstar # AM3S158, Karrier # AM31959, and Westlake # LHAXSJ101G is that the Loadstar is a bias tire which means it will perform better for off-road applications, the Karrier is a radial so it will do better than the Loadstar on the highway, and then the Westlake is more of the premium option with the wheel that...

  • Recommendations for a Trailer Light Kit and Tires for a Motorcycle Trailer
    We have numerous light kits available, but I recommend an LED light kit as they are both durable and draw a fraction of the power of incandescents. Take a look at Aero Pro LED Trailer Light Kit, # TLL36RK. These are rectangular LED lights that come with the wiring and hardware needed for installation. For tires, I spoke with our resident tire expert and he recommended using radial tires as they offer more stability and durability compared to bias ply tires. Take a look at Karrier ST175/80R13...
