tire size

[jon brooks]

I just bought a 2000 grand am se. It has 205/70/15 on it but is supposed to be 215/60/15, Is there going to be any problem with the speedo being off?

Check this site, use the calculator to see the difference;

There is a 1 inch difference in tire diameter so there will be a speedometer issue and the computer signals that depend on speed will also be slightly affected.
