    Seems to me 33x12.50x15 would be just a bit too big. Anyone have problems with this?

    it depends on how much you want to :hack: your fenders. I am sure you could get 38s to fit if you ditched the inner fenders :blush: :thumb: .

    I run 35X14's 3"b.s. with only a trim on the front fenders , no lift
    There seems to be a big difference between trucks as to how much lift is needed to run the bigger tires
    The type of wheeling also has an impact on the amount you need

    33x12.50.15

    I run 33x12.50.15 on my stock 88 GMC Jimmy. No trimming. I get very minimal rub on the front only at hard stuffing. This truck has gone through Uwharrie with rubbing at all.

    33x12.50's should fit with minimal trimming. All trucks seem to be different (even same year/model) so you may just have to try it.

    I just helped a freind do some minor trimming on his '77 3/4 ton pickup after installing a set of 33's. The front and rear needed a inch or so cut back. The rub was so minor that he considered just letting the tires trim the fenders themselves :eek1: but I conviced him to go ahead and cut it off before he cut his new tires.

    If you just want to keep the truck at stock stance and keep a lower center of gravity (or you don't have the money for a lift like my freind) then just plan on cutting a bit.

    My opinion is to put a 2 1/2" lift in there and see how it works. You might have to trim a tiny bit but it won't really chage the stance of the truck.

    Bottom line: It's hard to tell, just try it and see what happens. :D

    impossible to answer that question without knowing whether you want to fender trim or not. Without touching the fenders, prolly 32s or 33s. With mad trimming and firewall clearancing... who knows. 38s? 40s?

    zzzzzzzzzzzzzzzzzzzzzzz

    This has to be the 5th post asking the same question....

    I can see the originaly poster is new... not trying to be a a$$ here but the search on those kind of questions works great. the real technical questions is another story when it comes to search.

    Wheel width and offset plays a big factor. I ran 36x12.50 TSL/SXs on my K10 with everything stock including the 15x7 aluminum suburban wheels. A little trimming on the front and back of the front fender was all the was required. Due to the short suspension travel and fatory bumpstops, it worked great.

    it don't make a difference what rig you run them on at all its all in the rim. all you need to do is stay with a stock rim and keep the tire inside the fenders. the minute the tires go past the fenders you need to trim or lift

    So do I . I'm running 315/75/16's with stock suspension they fit perfect in the back. And I trimmed the front and back of the front fenders so they had room to turn. I run without the inner fenders most of the time. But I put them in with just a couple bolts before going to play in the mud.

    I'm running 33x12.50x15 sidewinders on my 86 K5 sans lift on stock rims. Only problem I have is the tire rubs the steering arm when you turn fully right. I'm planning 2" of lift and different backspacing with flares.

    I have a 4" lift on my 88 K5 and 35x12.50's fit with absolutely NO rubbing. I have not touched my fenders either.

    man up and trim.

    there's a pic on here somewhere of a k5 with 44s and 1 inch body lift.

    you can fit small tires with no trim. you can fit huge tires with trim.

    I know this is an ancient thread

    If anyone can dig up this pic, it would be very entertaining to look at.. I don't suppose they had much inner fender left, lol.
    thanks,
    James

    Maybe safe but how long do you think a pair of 10 bolts, a set of 44s and even a stock 350 are going to live together.
