But on aftermarket 20", many go with 285/30/20 in the rear.
I had 295/25R21 last year and my fuel consumption went from 0.55 - 0.70.... So this year i'm trying to save some fuel. And 295/25R21 was to little gum for a nice ride so thats why i'm choosing 20 inch in stead of 21.
Am i getting to old? :S
