Hi guys. A really quick question. I was talking to my friend and he is getting some new rims. His current rim size is 15X6.5. And his new rims are going to be 15X7. He is going to try to stick with his current tire.

So I was saying, if you do autocross or any high speed turns, your rims would touch the ground due to radial tires and how they freely move. Am I right or wrong? I'm 50% because its only .5 difference.

 

Only 1/2 inch difference, it should be OK.

Knowing the actual tire size (since you didn't tell us) you can check on tirerack.com for the allowable range of rim width for any particular size.

 

O my bad his original tire size is 195/55/15. It is on his Fit. and he's replacing it with some rims which are 15X7.

 

Those tires are a little narrow for a 7" wide rim, but will be fine.

 

Well street tires aren't really meant for AutoX but I just did it on mine and did fine.

Just pump them up a couple PSI higher and he should be ok.

 

I have a similar question. I wanna move from my current 18x7.5 wheels to 18x8 wheels. Will my 215/40 be able to handle it?

you would be stretching the tires a pretty good amount you might notice a slight loss in traction though

 

I was thinking since I have a 40 series that I may have a little leeway. They have rounded shoulders because they're falkens, does that make any difference with the fit?
