still trying to figure out what tires i'm going to run with 20" wheels...

i used to run 245/35/20 and 275/30/20 and i know the recommended oem specs are 245/30/20 and 275/25/20.

if i decided to run 245/30/20 and 275/30/20, 30's all the way around, am i asking for trouble? other than cosmetic, what issues might i need to be aware of? thanks.

dc

Your rears' outside diameter will be 0.36" larger than your front and 0.54" larger than 275/25/20. Your speedometer will be off but no different than if you ran 245/35 and 275/30

You don't want to do that with a stgrd setup. Just run 35-front, 30-rear like most poeple. I can't recomend 25 series to anyone after my experience. Too little rubber for a daily driven car.
