Tire size calulator

My motorhome calls for Michelin 275/80/22.5 tires. I was told that 295/75/22.5 were a replacement for my original tires. I went to this site to see what difference in size, mile mph were.

You're absolutely right. I use the same calculator.

Last month, I put two new tires on the front of our coach. The original size is 295 75 R22.5 . The dealer almost installed Michelin 275 80 R22.5 . I insisted on the original size tire. He had Bridgestone R280s in the original size, so that's what I bought.

Using the calculator, I now realize that the dealer was correct. Having said that, I am very pleased with the Bridgestone R280 tires.

When changing tire sizes, it's also a good idea to check spacing between duals.
