    Default 20 in rims tire sizes

    Anybody know what the max tire size is on the RT with 20 in rims? and can the back be a little wider ? I only have about a 1 in drop on from what i can tell it was done before i bought it if that helps. Thought i browsed over it at some point but can't seem to find the post.

    i use 275/45/r20 with my 20 inch R/T reps.
    i think this pic at the time was 275/55/r20s and they rubbed with the turns. they def fit the wheel well better than the 45's but rubbed

    I had two of my 20's widened 3" and have 345/30ZR20 tires on them. You can't go any wider unless you modify the suspension.3 inches wider by Weldcraft.jpgAS WIDE AS YOU CAN GET.jpg

    What did that run from Weld Craft? I have old tires on mine and want to widen them before I spend money on tires again.

    You have to go to their website. They send you an email with price and you send a copy of that email with the wheels so he charges you correctly. I took 3 months to work my project in and I'm sorry I don't remember the cost.

    12" back wheel is as wide as you can go without a spacer. Most people run a 1.25" spacer for the rear when running the 13" wide viper wheels.
