Smaller Diameter Tires - Speedometer is Fine?
I just put on 285/30-18 tires to replace 275/40-18 tires expecting to have to adjust the speedometer. There was no change! The tach and speedometer readings are the same as before. Am I missing somthing or what?

Since your new tires are slighltly smaller in diameter your speedometer will indicate you are traveling several mile an hour faster than you actually are going.

Thanks
Thanks for the help. I will being using a Predator Tuner to correct for tire size. By the way it also lowered the car and looks great. Oh oh, I think I'm getting mod fever. Now what should I do next???
