straight line or do you want to go through a corner over 25mph? your gonna have to run low air pressure to make the tire not crown and go bald in the center.451 valiant said:Has anyone tried cramming 275 60 15's on 7" cop rims. recommended rim width is 7.5-9.5" for bfg drag radials. Just wondering if it is even safe or whether the 1/2" will matter?? Any suggestions or has anyone tried??
