Changing from 5.70-8 Tires to 10 Inch Tires on a Trailer

Updated 06/23/2014 | Published 06/19/2014

Question:

I currently have 5.70x8 inch tires, 4 bolt, on my trailer. Id like to increase them to a 10inch tire but am unsure of which size of 10 inch would fit the axle. I have plenty of room in my wheel well to accommodate it.

As long as you have room in your wheel well for a larger tire and wheel, the only other factors that you will need to consider are the bolt pattern and weight capacity of the new tires. For example, the Kenda 205/65-10 Tire and Wheel Combo, # AM3H370, has a 4 on 4 inch bolt pattern and a maximum load rating of 1,100 lbs at 50 psi. A 4 on 4 inch bolt pattern is the most common bolt pattern for 8 and 10 inch wheels, so this combo should work as long as the load rating of two wheel/tire combos meets or exceeds your axle weight rating. I have attached a help article on how to determine your bolt pattern so you can verify the exact bolt pattern of your current wheels.

I have attached a link to all of our 10 inch tire and wheel combos with a 4 on 4 inch bolt pattern. Keep in mind, a 205/65-10 tire will be about 2-1/2 inches wider than a 5.70-8 tire. You may have enough room in your wheel well, but you will also want to make sure you have enough clearance between the inside wall of the tire and side of the trailer or suspension. A 205/65-10 will sit about 1-1/4 inches closer to the trailer.
