19/20 wheel questions
Just got my tracking number to my 19/20 Cray wheels and new tires. I gotta wait 5 more days. If you have this set up tell me your opinion ,has the ride changed because of the smaller side wall? How much do they throw off your speedometer? Did you re calibrate your speedometer and how? Any information would be greatly apreciated. Tom

I have 305/25/20 in the back and the ride is a little rough but overall performance is great and worth it.
Speedometer can be reconfigured, my any hand held programmer or Dealer, but the main thing the larger tire does it throw off your software high rev limiter.
My combo is z06 Motorsports 19/20 combo!

The over all diameter of the tire compared to the old tire is really what makes the difference.
Check how different they actually are.
You might be suprised and find out that there is very little difference from these tires to the OEM tires

I have 245/35/19 on the front and 285/30/20 on the rear of mine. Rides just fine and no noticable difference in the speedo.
