Default ..Front Wheel Diameter Different Size Than Rear?

..I've read that it's not good for the vehicle to run different diameter wheels like 15" in front, 17" in rear..but have also read where people do this..Can I have your opinions on this? Thanks

its not the rim diameter that matter, its the tire diameter that is kinda important. dont want different hight tires on one side, on the rear it can burn the rearend up. front can effect handling more so at higher speeds. different tire diameter for the most part can cause the abs system to act up.

Nooo, I didn't ask about different sizes side to side..I don't know what that means..My question is about front vs back..wheels only..I'm familiar on tire sizes and know that alot of us put larger tires on rear than ones on front..
I'm asking about WHEELS.. small on both FRONTS (say 15") and larger on both REARS (like 17") ... Sorry for the cconfusion

i have seen different wheel sizes up to a inch on the 4th gens but i think the tire size makes up for most of it. lower profile tire in back. we used to do 15s on back and 14s on front to get the rear up but it had a negitive effect on steering, sway worse and just not wanting to turn well.

People do it all the time. Think of drag cars with "big and littles."

I don't know if craby realizes this is a 1st gen car, lol
Bigger diameter wheels in back and smaller in front, no problems at all Jim-Bob.

That is one way to get a "rake" to the car.It all depends on the "look" you want for the car.And usually on what you want to do with it.(Road Race.Pro-touring. Drag racing .etc.) Usually we use the same diameter wheel all away around. The front tire and the rear do two different functions. So wheel/ tire clearance for the front wheel well .and then the back drives the car .So most of us try to put as much tire in back for traction.For what ever type of function you want the car do .
