comparing tires sizes??
does anyone know a site where I can compare tire sizes. I found one for regular tires like 255, etc. but not those sizes compared to say 10 x30" ones

I know my 2011 Wrangler Sport has the stock 17 inch wheels and tires that are 255/75/17. I can't remember where I saw it, but if I remember correctly the 255/75/17 equals a 32 X 12 tire. :)

If you go to TireRackdotcom, go to a brand and model of tire, and click on specs it will bring up a list of all sizes for that tire with height, width, weight, etc. Once you have what you need, look up the part number at DTD to purchase.


You can convert the communist size to real measurements fairly easily.

Width=first number diviced by 25.4 Example: 255/25.4=10", 285/25.4=11.2", etc.

Height is more involved. After you have done the width above, multiply it by the second number and divide that number by 50 and add the rim size.

For a 255/75/17 it would be 10"x75/50+17=32"
