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"

Great looking and visibly a great product especially when you consider the price! Now I have to wash the boat and make it look as good as the wheels/tires!

Great item and awesome durability
Kip B - 04/10/2021


Exact fit for my triton LT jetski trailer (just had to trim the plastic 12" oem fender with a small knife to avoid rubbing). Excellent built quality. Tires and wheel come mounted and air prefilled ready to mount. These are radial tires just like your car, prefilled to about 50psi from factory. I even purchased an extra spare one !. ** Must have **


These wheels are very nice and look great on my small camper trailer. This is a quality part. I would like to thank Roger R for the great service. Will not hesitate to purchase from etrailer again for all my needs.


Highly recommend e trailer. Bought 6 tires with wheels March 1st and were at my house on the 3rd. Awesome prices and customer service plus free shipping.


Beautiful finish, exact size and offset, tires come charged to correct pressure, arrived earlier then expected!


Excellent customer service and fast shipping. I returned smaller 12” wheels for these 13” wheels. The process was seamless as well! Thanks etrailer!


I needed help to guide me to the right tire and got perfect service from customer care. The items came in faster than expected and I’m extremely happy


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.

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.
Phillip H - 10/14/2018


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.


These wheels and tire setup were shipped and packaged well... After a year of using them, there is no rust and the ride is as smooth as a car tire. Really recommended ! ... i use them on a 850lbs yamaha svho on a Triton LT series trailer.


They had exactly what I was looking for, had it in stock or available, shipped it right away for free and it came early. It fits and looks great. I don’t ask for any more than that,


Great job on making the delivery, will deal with your company in near future


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.


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


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 great website and very knowledgeable staff.


The nice upgrade makes my 2003 boat/trailer look newer!


Product delivered rite to door step. Very much satisfied. Thank you for the great service.


Great product and great price with the combo including the spare tire bracket and free shipping what a deal.


I have yet to install the tires. However, I was very pleased with the customer service, the speed of delivery, and the overall appearance of the product.


Looks great


Looks great. Very quick delivery and looking forward to upgrading my boat trailer.


Great Products and Excellent Customer Service! Would Buy Again!


Exactly what I ordered.


Great products and prompt delivery very happy would recommend them to anyone


Great value!

  • 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.

    Yes, you can use the Karrier ST175/80R13 Radial Trailer Tire with 13" Aluminum Wheel part # AM31959 with 10" drums. Generally speaking, 13" wheels are the smallest that can be used with 10" brakes so there will not be an issue with this setup.

  • Can I Upgrade The 12" Wheels On My Trailer To 13" Wheels?
    Upgrading wheels on a trailer is a pretty common thing to do, but you want to make sure you have the space to do so. You should have at least 3" from the top of the tire to the bottom of the fender/wheel well and then around 1.5" between the tire's sidewall and the side of the fender/wheel well. This measurement is less important than the space at the top of the tire, but is still something to keep an eye on. With that said, as the average 5.30x12 tire will have an outer diameter of 21.9"...

  • 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...

  • Will Kenda 175/80-13 Loadstar be Able to Hold Weight of 1983 Calkins Boat Trailer with Boat
    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. You are correct that automobile tires are not suited for trailer usage and so switching the correct tire/wheels...

  • Comparing Loadstar, Karrier, and Castle Rock 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 Castle Rock # 274-000049 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 Castle Rock is more of the premium option with the wheel...

  • Best Option For Low 3,500 lb Axle Suspension
    Thanks for the drawing, and I think we may have an option for you here, though there isn't a traditional through-axle that can work for you with those dimensions. The reason for that is for a standard 3,500 lb through-axle, the shortest you will find is 89 inches from hub face to hub face, which is quite a bit further than the 70 inch width you have so the wheels would stick way out. So instead I the Timbren Axle-Less Suspension System, which are simply bolted or welded so you do not have...
