I want to go to 17 inch rims in my Camaro but will I have to mess with the speedometer? What do I have to do to make it work?

 

Nothing, if you just go up +1. For example:If you go from 16'" wheels & 245/50 tires to17" wheels and 245/45/17 tires requires no change in the speedometer. The wheel & tire height did not change.

 

naw on my 95 i just put 17's on it and didnt notice anything......

 

Just use a lower profile tire that matches the diameter of tire you have now.

Type in your tire size now and the size you want and any optional sizes and it will show all the different measurments and a general idea of what your speedo will read with the different sizes.

 

i went from stock rims to 18 inch.. didnt see a diff.. tire size is 245/45/18

 

To keep the same speedo ratio with a 17" wheel you need to run a 275/40/17, of course the aspect ratio varies depending on how wide the tire is, but if you're getting aftermarket wheels you should probably go with a 17X9.5.

 

Thanks alot guys. I'm getting some black vette rims so I needed to know.
