Nice, never thought a 20 would be shorter than a 15!

Gregsmx · 04-17-2003, 11:16 PM

Brad, do you still have the tires handy? If so, can you measure the total height of each of the three tires. That's a great pic, and valuable information when tire hunting! Width of each would be handy also.
Thanks, Greg.

I'd say 8" on one, and 10" on the other...

Yep and 8 and 10" wheels. Cool link N2trux. Guess I don't need to measure those tires now.

Always remember that the numbers on the sidewall are "advertised" size, and will not all be the same.

What that means is if you take three 275/50/15 made by three different companies, they may all be different sizes.

Heres a comparison between 20's and 24's. Sorry for the HUGE pic...
