I just purchased some 215 reps from
www.eurotechwheels.com...
I am running 22's now.....So I was going to buy the 21" 215's.....what dropped me down to the 20" was the fact that the 21" tire is so hard to find and quite expensive... if I ever caught a flat ...it seems it may take a few days to a week to get a new tire.....as my Indy explained..
Hope this helps..
