I need help on finding out who can set my 2004 impala tire diameter bigger in my computer. I have 22s with 245/30/22 and the tires diameter is different than the stocks therefore causing me to go faster than my speedometer says...and my odometer might be wrong as well. I did not put them on yet and I wanted to get this done before I do.

Or maybe some names of some shops that do speedometer calibrations.

Thank you and this is very much appreciated.

 

PM "REY" on here.
He might know of someone that can do that.
