My 01 Seville SLS needs tires. I have an opportunity to buy a set of Firestone FR690 tires really cheap. They are 235.65R16 rather than the 235.60R16 that are on the car. Will there be any issues with changing the tire size and if so what are they?

It may throw your speedometer off slightly. There are some websites that will calculate that for you. tirerack.com may have one

The sidewalls will just be slightly taller. Try one on and step back and see if you like the look of the larger tire.

Whatever you do, you probably shouldn't go any WIDER (terrible steering sensitivity). I know nothing about tread size, etc. so I can't comment on that part.

About a 2 mile difference at 60 mph. You can have your comp reprogrammed to display correct speed I believe.

As far as steering sensitivity, you'll never notice the difference IMO.
