I think I need 60 ratio, not 50...

Well, I bought 205/50r15 quatrec and now it’s showing 83mph when I am doing 80 and runs at 350-400 rpm higher than before.
Dang it. Tire rack.com again.

Smaller tire will do that.

:agree: ….. Every post I ever did on the Quatrac 5 ( about 100 or so :roflblack: ) I have always said " 60 " aspect ratio ….. What you have with that tire is Quicker acceleration ….. not a Bad thing ….. Mike :ohyea:
