Bias Tires vs. Radial Tires

Bias vs. radial tire graphic

Bias ply tires are designed for off-road or agricultural applications. They are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.

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 - AM30156 Review

Today, we'll be taking a look at part number: AM30156 - the Kenda 5.7 X 8 Bias Trailer Tire with an 8" Galvanized Wheel. The Kenda 5.7 X 8 Bias Trailer Tire on 8" Galvanized Wheel. This wheel does have a galvanized finish for superior corrosion-resistance. It does measure 8" in diameter by 3-3/4" wide. It has a 5 on 4-12" bolt pattern. To get these dimensions, we obviously know that it has 5 lug bolt holes, and if you draw a circle through the center of each of the 5 bolt holes,and measure the diameter of that circle, you get 4-1/2".

You can also measure from the center of one bolt hole to the center of the bolt hole right next to it, which in this case would be 2-5/8". And using the chart on the product page, you know that that with 5 bolt holes and a 2-5/8" length, you have a 5 on 4-1/2" bolt pattern. The wheel has a capacity of 910 lbs. and a wheel bolt hole size by 1/2" X 20". Another important piece of information that you do need to have is the pilot hole diameter.

This is the center hole in the wheel that will fit over axle hub. This wheel has a 2.8" diameter pilot hole. Now, we'll move on to the tire. This is a Loadstar 5.7 X 8" It has an overall diameter of 18". It has a load range D, 8-ply rating tire, which gives it a maximum load of 1,075 lbs at 100 psi.

It is of bias construction, which means the belts within the tire run the length of the tire. This wheel and tire combo comes with a two-year limited warranty. And that should do it for part number: AM30156. .

Very good tires. Fit perfectly and had great customer experience. 596821

- AM30156

These tires are awesome. They fit properly and seem to be of very high quality. They are exactly what I was looking for at a great price. The website made it easy to determine the proper tire to purchase with all of the specs and dimensions for tire and rim size. I built a rack on my trailer to hold multiple boats and needed tires that could handle the extra load. The tires arrived quicker than expected as I used standard shipping. Ordering was easy and shipping was free. 527312

After a year the tires and rims are still in great shape. Very satisfied

I've had these tires on my snowmobile trailer for a year. They have held up very well thus far, and the galvanizing has remained in excellent condition. Great purchase for the price. 640562

- AM30156

The tire is fine but why match a Load range D tire to a load range C rim? This always made me wonder but I guess most customers don't check the rim load range. Also if you want the D load range you need to put 90psi in the tire, and keep it there! 606960

The Kenda tire and galvanized wheel look great. I was very impressed with the low price and speedy delivery. My order shipped free the day of the order on a Thursday and was in my hands on Monday. Also no sales tax. 580359

Well made and at great price. Harder to find tires in this size with a D load rating. This should solve my flat problem. 554197

Needed these tires during vacation when the tread separated on existings tire during our trip. Delivered as promised before our return trip started. 538836

Thank you the wheel tire combo was just what I was looking for. I hope that theses tires last as long as the 1st set I bought from your company. The axle I purchased many years ago is going strong. 526233

Nice set of tires and rims. I have owned this utility trailer for over twenty years, it had belonged to my father-in-law. He purchased it new in 1967, except for the tires the rims were original, after 50 or so years it was time to upgrade that's why I chose the galvanized rims, the 5 bolt pattern was spot on and the trailer tracks beautifully. I have been doing business with etrailer for many years, and with any luck will continue for many more. 522738

- AM30156

Absolutely a Great Experience purchasing tires from ETRAILER. These tires are now on my older jetski trailer. We purchased a newer ski, which is heavier, and the smaller 8inch tire just didn't seem right so i went with the next size up. It fit with no additional adjustments. The transaction on the phone went very smooth. I even was notified that my tires would be delivered earlier than originally thought. Thank you for a great experience. 522110

Great product. I was running 4.8-8 boat trailer tires and I wanted a higher load rating. Helen was extremely helpful with selecting. I thought about going to a 12" rim size, but decided to go with a 5.70-8. I purchased 2 of the AM30156 and they are amazing. I feel everyone should replace their 4.8-8's with these units, as long as they have enough clearance. They are slightly wider and taller so check that out. They are a much more robust product, they are a load rating D instead of B, and my trailer tires don't look grossly undersized now, even though I didn't step up to a 12" rim. The 8" galvanized rims look great. I had these bolted on my trailer within 12 hours of receiving them. Great job etrailer and Helen! 509325

The product is awesome!

Like the wheels, but had two problems. One had a valve stem leak before I put them on, so had to fix that, and the other had defective galvanized area where rust had formed, again prior to installation, but since it was on the inside I figure it would cover with grease. Other than that they're great! 391840

Great product at a great price. Used these on a jet ski trailer. These galvanized wheels are a good choice for boat trailers because they resist rust much better than their powder coated counterparts. Locally, the tires alone cost as much as this combo. 199175

  • Speed Rating for Trailer Tires and Troubleshooting a Bouncing Trailer
    All of the trailer tires we carry are rated for 65 miles per hour which is suitable for highway speeds. A 4.8-12 trailer tire, like the Kenda K353 Bias Trailer Tire, # AM10062, is rated for 90 psi. You should always inflate a trailer tire to the max psi rating indicated on the tire. Trailer tires are made with a thicker side wall to handle more vertical load. Under-inflating a trailer tire will cause excessive heat build up and cause the tire to fail.

  • What Is Speed Rating of the Kenda Bias Trailer Tire and Wheel # AM30156
    Special Trailer tires, (ST rated) will have a maximum speed rating of 65 miles per hour. It is not recommended to travel faster than 65 miles per hour as heat can buildup inside the tire and cause tire failure. I have linked an FAQ on trailer tires that you may find as a good reference.

  • Trailer Tire Recommendations for a Trailer Towed by a Motorcycle
    An 8 inch tire is perfectly fine for a motorcycle trailer. It will probably be easier on the bike. A couple of things you mentioned do wave red flags. First, tire pressure. Trailer tires should always be inflated to the maximum psi as indicated on the trailer tire. This is because trailer tires are specially constructed with a thicker sidewall when compared to passenger vehicle tires. When under inflated the thicker sidewall generates excessive heat and can fail. The other thing to...

  • What is the Weight Capacity of the Kenda 5.70-8 Bias Trailer Tire with 8" Galvanized Wheel AM30156
    Load Ranges for tires can and will change based on the tire size. Not all Load Range C's have the same capacity. The most important factor to consider will always be the stated capacity at the max tire pressure. The part # AM30156 that you referenced has a 1,075 lbs at 100 psi so that is it's actual capacity regardless of it being a Load Range D. The Load Ranges are basically designed to easily organize tire capacities based on size.

  • Replacement Tire and Wheel for Tires Rubbing Against Trailer
    I recommend going to a more narrow rim and tire to solve your issue with sidewall rubbing. Depending on the load range you need, there are a couple of options. I suggest taking a look at the Kenda # AM3H220, which is a 165/65-8 tire with a maximum load of 800 lbs at 70 psi and has a rim that is 8" diameter x 5-3/8" wide. You can also take a look at the Kenda # AM30156, which is a 5.70-8 tire with a maximum load of 1,075 lbs at 100 psi with a rim that is 8" diameter x 3-3/4" wide. Both...

  • Recommended Tire And Wheel Sizes To Change To For A Camper With 5.70-8 Tires
    When you say blowouts and attribute them to heat buildup, you are correct. The reason you have heat buildup in tires is not just because of the size, it will also be from overloading, damage to the tires and age. So to just change size first might not solve the problem. If the tires hit curbs a lot it would cause damage to the sidewalls and form a weak spot, which would allow the heat to buildup and go to the weakest spot in the tire and fail. Also any punctures or repairs to the tires...

  • Fit and Compatibility of 4.80/4.00-8 Trailer Tire on Waverunner Trailer Equipped with 5.70-8 Tires
    It sounds like your waverunner trailer has the 5.70-8 trailer tire on it. The smaller 4.80/4.00-8 Bias Tires # AM30070 you referenced would fit your 5 on 4-1/2 inch bolt pattern but may not be compatible with the weight rating of your trailer and waverunner. The Load Range C # AM30070 has a capacity of 760lbs at 90psi for a total axle weight of 1,520lbs. If your trailer and waverunner are within these limits then this combination could work for you.
