I would like to put on 33x12.50 r20 on my 2003 1500HD with a leveling kit,but i was told i need a lift by one person and told they would fit just fine by another person,so i don't know what to do,can anybody help?.thanks.

 

Give it a shot before you buy the 20s.... The largest Ive seen in a non-lifted hd is LT285/65R18. This gives you a 32.7 * 11.50 on a 8.5" wide rim. Here is a good tire size chart. Its only for the BFGoodrich All Terrain TA but you can back out and look at any BFG tire and there specs..... Good Luck

You can fit 33" no problem. Crank the t-bars and you'll be just fine. If rubbing occurs, tie back the brake lines to the frame and trim the fender walls. Also good idea to cut the front valance a bit for fitment. Go to Diesel Place and search for H2 fitment... they are 33" tires.

 

I really would not suggest cranking the torsion bars. Go buy a 2 inch body lift if you really need to, it will save you time and money on repair cost of cranking the torsoin bar. Youy should be fine without the lift.
