how tall is a 22 with a good sized tire on it

im hinking of doing simis but i need to know how tall thay are and if im going to be able drive with a bd

Well if you are going with a BD you will more than likely run a 265/35/22 and they are 29.3" tall.

255/30/22 == 28.0"
265/40/22 == 30.5"
305/40/22 == 31.6"
305/45/22 == 32.8"
