tires

I believe most of the Grand Prix's have 225/60/16" tires. Is it OK to run 225/50/16's or will cause trouble?

Re: tires

when you run smaller tires all you probably need is to get a speedo adjustment (aftermarket electrical device that mounts in-line with one of the trans sensors on our cars) when you need to worry is with bigger wheels sometimes you have clearance/rubbing issues

Re: tires

Re: tires

Nope. Too oddball. When your speedo reads 65 mph, you will actually be going 60.68 mph. One benefit is your acceleration may be a little bit better but fuel economy will probably suffer.
