    Default Yes! 33's will fit under a stock K1500

    Yup, it's true. Just purchased and installed some 255/85/16 Bfg Mud Terrain KM2s. They actually measure 33.8x10.50. I previously had the torsion key turned a couple of times. I think it was equivalent to about 1.25 when I measured from the ground to the bumper. But it does not rub and it's not even close. Even when it's flexed.

    Looks good! And if they don't rub, then perfect!

    Lucky you! I've got a little rubbing issue. Nothing a dremel can't fix.

    thanks, discount tire. Just awesome service there, I had Michelin ltx's on the truck they had about 15k on them and the side walls were cracking. Discount tire offered me $152 a tire toward BFG or Michelins which are the same company. I got all 4 for $600. I jumped on it.

    I know, I figured I'd be trimming something too. I think it may be due to the HD package and the fact the truck is a half heavy. Who knows.

    Thanks again fellas, cheers

    wait, 255/80R16s stack up at 33"?.....

    i though the conversion was 285/75/16 = 33"
    thats what im thinking of getting to replace the 265/75/16 i have now. i think they come out to be about 31"

    the trick seems to be to have aftermarket wheels with an offset. the stock wheels hug too close to the body

    Multiply the first number, the tire width, by .03937. This will convert the the width from millimeters to inches. Using the above example of 255 millimeters, the tire would have a width of 10.039 inches....

    Multiply the tire width by the percentage found in the aspect ratio, which is the second of the three numbers in the tire size. Using my tire, the sidewall is 85 percent of the width, or 8.533....

    Multiply the sidewall width by two. This is necessary in determining the wheel's diameter because the sidewall is featured on both sides of the tire rim. That's 17.06 inches of sidewall...

    Add the total side wall to your rim size 16. 33.06 x 10.039 r16.. My BFGs are just slightly larger cause of the lugs on the tire. But that math works for everything..

    Ah you may not need new rims, the stock ones or aftermarket rims that have the similar offset actually clear better, unless you have like 12.50s and need the wide rim which needs the off set. But my 10.50s clear well even flexed

    cheers!
