That said, you should be able to get away with putting 305/35's on 9.5" wheels for short-term or emergency needs. But I wouldn't ever do a combination like that as a mount 'em up and forget about 'em until they're almost bald mod.




At least partial blame belongs with those organizations who have insisted on pedestrian-protecting hood contours. Seriously. Moving the hood lines and the belt line up tends to make smaller wheels look, well, a little too small. It's a proportions thing.

Correct but Tire ratings are like Clothing size ratings. Just because X manufacturer says Y shirt is a XXL doesn't mean that is what it really measures. So all of those ratings out there are simply a general guide line because not all 305 tires are the same width...or even close for that matter.

Here is the proof.... Both 305's
