You don't drive on the rim. The rim size means NOTHING. As Seth
pointed out in an earlier post, it is the overal diameter of the tire
p.s. check this site so you can see for yourself how tire O.D. is what
You don't have 15" tires. You have tires that sit on a 15" rim and have an
outside diameter larger than 15". It's that outside diameter that counts.
You could put on a 9"rim and if the tire has the same outside diameter
nothing will have to be changed or adjusted.
I put a wider set of tires on a car than the car would accept. But, I
remembered this making turns, and the tires would only hit the frame at
full lock. In that car, full lock was about a 90 degree turn! So I wasn't
too worried about it...
But, there are other things, too. Tires of one size fit on rims of a
certain width. I wanted to put 195/45-14s on a Corolla, but I need a 1"
wider rim (I had the rims on a Celica that would work, but gave the car
away...). Otherwise, the tire may blow off the rim in a hard turn.
Also, check the clearance of the flanges that hold the springs up. A tire
with too much of a diamter may not clear, or rub when going over bumps.
Let's say your original tire size is 205/60-15. A wider, lower profile
tire will give you better handling. In this case, keeping the original
rims, then you could probably go 225/50-15. You'll get decent handling,
good ride and save about $1000...
That is, if $$$ is an object!
Well, you know I meant rims. I was thinking about wider tires also. Would
that be much of a problem? See, I see most newer cars or a higher price
seem to come with 17" wheels and I would like to get into that territory. I
would like to improve the wheels and tires in many ways. I am not going all
out as far as expsenisve rims, I am just keeping it in the $400-$500 range.
The tires will be what they will be.
they look cool, but unless you drive on glass, the lower profile tires
necessary to keep wheel diameter make them more easily dented on pot
holes. i'd consider keeping stock and spending the money on decent
