    Thumbs up Wheel size and offset for nnbs

    Looking to throw on some KMC Hoss' and going for the 20x9 fitment.

    Does anyone have these on their stock hieght NNBS?

    what offsets do you reccomend/use? i've seen +12, +15 etc when I searched.

    also, any recomendations for tire size as well...looking to not get to aggressive. Largest would be a 33.

    thanks guys.

    Go + for sure. Something in the neighborhood of + 18 would be ideal. You also are pretty much stuck with the stock sizing too unless you look into some type of lift.

    yeah, i want the deepest lip i can get with these rims. what offset are you running? I will be adding a 2" leveling kit later...its just that i love a jacked up truck but i drive 40+ miles/day and gas is killin. I get 17gpm as is now.

    -25 on x10's. These trucks don't handle larger tires well, because the fender wells are very narrow. You aren't going to get much lip at all with a x9 anyway and the more positive the offet, the least as far as tire fitment is concerned. Unless you want to trim, a 275/60/20 is about as big as you can go.

    I have to agree with Blackout07. I test fitted 285/60/20's (34.7 inches I believe) on mine which has a 2 inch front level kit installed. The tire rubbed the back of the fender wells when I turned it right and left. It even popped out the plastic button that attaches the wheel well to the body when the tires rubbed against it. If you have an 18 inch rim as long as it has no negative off-set, you could get away with 285/65/18 as long as you have the 2 inch leveling kit. They are very close to 33 inch tires (33.2 I think). I have 275/65/18 tires on my factory rims and they are 31.9 inch tires.

    thanks, I don't want or need anything insane. soon, I will do the level kit, but for now im concerned with rims and tires as I can purchase them for cost, but I have to do it ASAP. 285/50 or 285/55 would be Ideal. Blackout, you have a serious set up, I likes.
