Expert Reply:

To get a speed rating of 81 mph, you can purchase the tire and wheels separately and have them mounted at a local shop. You would use the wheel, part # AM20122 and the tire part # TTWSF48012C. I attached videos of both of these products.

If you can settle for speed of 65 mph, you could choose a pre-mounted pair from the attached list.

I have the perfect size tire and wheels for you but the 4.80/4.00-8 tire is not the same as the 4.80-12 tire. Both tires have the same section width of 4.80 inches which is found by measuring the length of tread across the top of the tire. However,…

You will need to verify your bolt pattern even though it is very likely you have a 4 on 4 inch bolt pattern like what the #AM3h330 that you referenced has. You will want to measure from the center of one bolt hole to the center of the one across from…

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…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

Answer 8

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…

Answer 9

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

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…

The 12 inch tires that we carry are rated for 65 miles per hour. Any faster than that for extended periods and the excessive heat build up will cause tire failure. To get a tire with a higher speed rating you would have to go up in size. That also…
