My favorite at 1010 Tire, actually shows a pic of the tires for comparison.

Here.

Omicron,

I like the 1010 site except for one thing. When they resize the tires the also resize the rims in the process. A 145/25-18 will have totally different rim size compared to a 355/95-18. Put the values in for a pretty funky picture.

It gets the overall tire diameter correct but it doesn't get wheel quite right.

Otherwise it is a really cool visual display.

the best way to get this info is from the tire manufacturers websites... any other way is just a calculation made with a few assumptions that the tire is exactly the size on the sidewall (not always exactly the case)
