    Default need tires for some 20's...what size?

    I have a 2008 chevy silverado reg cab short bed 4x4. And I picked up some 20's from for a heck of a price, just couldnt resist. Now I am tryin to figure out what size tires to put on them. I am wanting to go with a semi aggresive looking tire. Like a nitto terra grappler or a goodyear wrangler at/s. I know the oem chevy 20's that are on the 08s are like a 275 55 20. Curious what the biggest tire is that i can fit, and if anyone has done a similar install, thanks!

    yeah, i was not really looking to purchase any wheels. But when i saw that i could get 20's for 100 a rim i was like i would be stupid to pass these up, and they were kind of the sytle i was considering. oh, and it was free shipping to my door also!!

    20" Nittos are cheaper than 17" Goodyears. 325/60/20 is what's on mine, leveling kit only.
    Cummins, 4uck the rest! Leave the chevy's to the ni66ers.

    I grabbed a set myself after seeing your posts. Great price on 20" wheels.
    Thanks for the heads up!!
