I spoke with our resident tire expert and he said that a 225/75-15 tire like # AM10256 will fit on a 15 x 7 inch wheel. However, he added that on a trailer, you do not often see a 15 x 7 inch wheel. That is because for trailer use, you would want to keep it more narrow.

Otherwise the sidewalls can bow out more. This can be a problem because trailer tires have a thicker sidewall and if bowed out more than normal it can build up more heat faster and lead to short life or failure. Another thing you can do to help prevent pre-mature wear is to inflate the tire to the maximum psi rating on the tire. In this case, it is 65 psi.

A 7 inch wide wheel (on the inside where the tire sits) is the widest wheel that a 225/75-15 tire will fit on. The same tire size will also fit on a 15x6 or 15x6-1/2 wheel. You would have no problem using any of the 3 sizes as a spare. I have…

Answer 6

The diameter of the tire would not change if you went to a narrower wheel by 1 inch. The wheel being narrower does not push the top of the tire up higher. A tire like the #AM10303 would work great. It fits tire widths of 6 inch to 7 inch in width too…

Answer 7

It looks like the previous owner of the trailer had vehicle tires installed since there are very few trailer tire manufacturers that carry a 235/75R15 size. Even though it might work for a while, trailer tires are always better to use for trailer…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Answer 11

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for…
