    255/50-20 is the largest that you can go with stock rims 16", not certain about 18" rims.

    10 Chevy Traverse LT AWD
    02 Chevy Trailblazer LS (110K+ miles - loaded except for 4WD - WRECKED!)
    99 Chevy Cavalier LS (105K+ miles - commuter car)
    78 Chevy Suburban Silverado (454, 3/4 ton)

    What are you looking to do? Get the most tire that you can without having to do a suspension lift, etc?

    I'd take a trip down to a tire/rim shop and see if they can give you some advice. I'd be interested in hearing as well.
