    I was wondering if I can get away with 32x11.50 or even 33x12.50 tires on my stock height '85 K5(came with 31x10.50x15). I was planning going with BF goodrich AT tires and using my factory 15x8 wheels(I believe that's what they are ). I don't plan on much off-road this year as I NEED it for reliable transportation .....But by next year it will be seeing some serious DIRT!! How does eveyone feel about bodylifts for tire clearance?? Would I be better off going with a suspension lift??

    I just put 33 12.5 tires on a 10 inch rim on my 83 Jimmy. Beware I did have to trim the front and the back of the fender on the bottom a little.(whiz wheel works super). the rear tires fit perfect. I have a stock ride height with a stock diesel motor. Also consider your gears, I rarely ever put her in overdrive anymore. I think she's got 3.42s. hope this helps

    31's is all i could get away with, without a lift or trimming the fenders! Still when I made sharp turns it rubbed like a B%#*$

    I dont think you can get away with 33s. I have BFG AT 33x12.50s on mine with 2" add a leafs, and I still rub when I flex alot. Plus I have 15x10 rims. Your 15x8 rims will actually make the tires stand a little taller than mine. Those are good tires though, I have had mine for 6 yrs, and my blzr is a daily driver plus weekend romping, and those BFGs still have "almost new" tread on them. The only thing I'm changing when these need replaced is MT instead of AT and up to 35s.

    I got a 3" body lift(soon to be a 4" suspention lift)with 33" x 12.5" BFG A/Ts . No problems yet, my truck runs great offroad. No rubbing or anything. But I wanna slap in that 4" suspention lift and get rid of this body lift ASAP! Not that I hate it. I just think that the suspention lift would be much better.

    I've seen a lot of K5s with 33" and no lift but it is probably only good for the street and it probably even rubs then. If you get a 2.5" suspension lift you can fit 33s and I've even seen one with a 2.5 lift 35x9.5x15 but that is a really narrow tire and it probably rubs really bad.
    I'm pretty sure 32" will be fine. I hope this helps

    Go see some pic's to help make up your mind at my CK5page if you want. 32"11,5 looked great and had enough clearence before I did my bodylift. Now they look like insybitsy go-cart wheels..

    32 X 11.50s will fit with minimal to no rubbing with stock suspension.

    hello,
    I have 33 12.50 15 BFG AT's on my 86 K5
    All i did was bend in the rear corners of the fenders and fold in the front lip on itself. I get no rub on or off the road.
    I sent a couple of pics so you can see how it looks.
    BY THE WAY MY RIMS ARE 15x10. 15X8 MAY RUB.

    here is a shot of my 33"Dunlop MudRovers on 15x10 wheels.
    Notice the front of the rear fenderwell is pushed in, thats from the tires hitting while wheelin and I have 4"suspension and 3" body lift. I have sence finished the job of bending the corners in with a 4lb sledge hammer. Someday if I ever get the body reworked I'll have the bent corners cut off........
