TIRES & RIMS
1. Nitto Ridge Grappler Tires ($329/ea)
275 /65 R20 126Q E1 BSW , 9" wide with a +10 offset (Stock is 275/60-20, 8.5w/+44)
2. Readylift 66-2120 Lift Kit (~500-600 parts+install)
3. RBP 94R Rims (Sexy Chrome with Black Strips, uncommon so better) ($1800)
9" wide rims with a +12 offset
As listed above, my truck is a 2x4 so clearance is just a little bit different than 4x4, but not much. The setup listed above makes for a 34.75 wide setup, which is pretty much the 'max' my truck can handle with the lift on. I get the smallest amount of rubbing when I take a sharp corner really tight, and if I was to do off-roading really bumpy, I'd prolly get more. The rubbing has to do with the fact I moved the tires out (+10 offset vs factory +44) and the size (from stock 33in diameter up to 34.5).
Without the leveling kit in the front, there's no way I could have upgraded the tires.
Pictured here are two sets of pics, both with the FACTORY tires (PVD Chrome Lariat, Goodyear) and my NEW tires (RBP Rims/Nitto Grapplers)
I haven't re-calibrated with FORScan just yet, but my initial testing shows my speedometer is just barely under 1 MPH off. (I'm going 1 MPH faster than dash says)
