    Ok so right now I have stock OEM rims (16x7, 40mm offset) on my 2002 Xterra. I am thinking about getting some Mickey Thompson Classic III Black Wheels in the 16x8 size so i can keep my new tires. However they have a 0mm offset and because of that they will stick out approximately 2 inches further than what is there now if I'm correct. With the tire sticking out 2 inches further, i was wondering will their be any obstructions between the tire and the body of the car. Im afraid if i hit a bump or anything the tire will rub on the fenders because they are out further. I currently do not have a Body lift or Suspension lift as the car is at its stock height for now. Please give me your thoughts. THANK YOU!!![h=1]Mickey Thompson Classic III Black Wheels[/h]

    That will depend on the size tire you run.

    I ran 16x8, 4.5 inch backspace, 0 offset w/ 265/75/16s for awhile. To get mine to fit around town, I cranked the t-bars, trimmed the front plastic bumper, trimmed plastic in the wheel wells and hammered the pinch welds at the bottom of the doors. I eventually added a 2 inch body lift to get them to stuff and fit off-road. With stock size tires (265/70) you should be able to get away with just trimming the plastics.

    I love the stance mine has with set-up. If you have any questions, or want pictures just give me a shout out . I have a few in build thread also.... Good luck. Just be aware that if you ever plan on going up in tire size, you will be cutting metal

    Thank you Ibishop for your reply. Yeah i plan on keeping my 265/70 16 tires. Pictures would be awesome. So even with the tire sticking out 2 inches further i would have to trim some plastic? I wouldnt have to trim any inner fender plastic right? Just outer fender?

    hey man sorry it took me a little while to get back to ya w/ those pictures... im away from the truck at training

    first is front bumper...
    trimmed the lip where the bumper comes into the fender. i eventually removed the braced up part in the fender for more clearance

    rear of the fender...
    trimmed the lip where the mud flap comes into the fenderwell. basically cut the whole bottom off the mud flap

    stock tires on the same size wheels your looking @. this is what your set-up is going to look like. but i was post trimming in these pictures. i wouldnt think you have to as far trimming wise as i did. the name of the game is clearance though on compression. i trimmed a little and he checked clearance

    and n idea of the stance

    I cant give you a for sure on how much trimming your gonna have to do, but it should give you an idea. tire type and stuff is gonna play into also. good luck man

    The amount of clearance is more related to the backspacing (BS) than to the offset itself, as offset's im pact is dictated by the rim's width, but BS is independent of rim width.

    You say your current tires are only teeny weenie 265/70/16, or ~ 31 x 10.5 nominal size.

    They currently fit, because you could fit 265/75/16 for example on a stock 2000 - 2004 X, with stock BS. (Those would be ~ 32 x 10.5 nominal equivalents)


    On an IFS, when you decrease the BS, it makes the tires swing in a wider arc. When you swing a longer baseball bat, you hit stuff farther away than with a shorter bat...and, when you swing that tire though that wider arc, it also hits more stuff.

    On your X, that means the front (Only the front) tires will hit stuff they would have missed with the correct BS.

    To use rims with too little BS, you therefore need to remove the stuff you don't want hit by the tire.

    You can bash the metal back with a BFH, sawzall, etc...but, no matter what you do, for the same work, you could have mounted a larger tire...with 5.5" of BS.


    The tire is a functional part of your rig, and, using a smaller tire than you could have generally makes it work less well. A wider stance is more stable off camber, and improves your center of gravity....

    ...and there's two ways to get that:

    1) Use a fatter tire, trim only plastic.

    2) Use a skinnier tire on an out rigger, like a training wheel, etc....and cut off metal and plastic.


    Your current plan is for the training wheels, so, you'll need to bash back and cut off the parts of the truck (Just in the front wells) that the tires hit....just to use your current wee baby tires.

    So, if afraid that the tire might rub...yes, it will....and you just get rid of what it rubs on.

    :D



    BTW - W/o knowing the width of the rim you want, the offset doesn't really tell us much.

    For example, 40 mm of offset on a 7" nominal rim width = 5.5" of BS.

    Zero off set on a 10" nominal rim = 5.5" of BS....which would work as far as clearance, but be too wide for the wee tire.

    And so forth.

    @tj the Mickey Thompson wheels he's looking at are 16x8 wheel

    Tj is the man to listen to when it comes to wheels, back spacing, an getting those suckers to fit. The general consensus around here seems to be though if your dead set on runnin after wheels 4.75 is about the lowest you want on back spacing. Some guys run less, myself included. I opted for 4.5 inch backspace so I would have more aluminum wheel choices. The flip side of that coin is like Tj mentioned above there is cutting of metal involved to get everything to fit.
