I'm looking to put 33x12.5 Goodyear Duratrac tires on my Alcoa Wheels (See below I with information from the forum). Do I need wheel spacers since they are much wider then my 31x10.5xR15?


I have a 2"(light spring) ARB/OME suspension lift. Thinking about adding Savvy Aluminum 1.25" body lift and Browndog MML.

I wish Goodyear made a Duratrac in 32x11.5xR15, but they don't. They make it in the MT/R(32X11.50R15). If I put back on my original wheels(MOAB), I could do 265/75/R16 Duratrac, which would be close.

Confused and weighing out options of going to Duratrac 33x12.5/R15, go back to old wheels(MOAB) for Duratrac 265/75/R16, or just look for another tire brand in the roughly 32" range.

I appreciate any help or feedback!


I. Alcoa

15x8 forged aluminum
* 5 on 4.5" bolt pattern
* Backspacing = 5.5"
* Offset = +25 mm
* Standard wheel with 2004 Rocky Mountain Edition and 2006 65th Anniv. Edition

I have the same lift and use factory Ravine wheels with the same backspacing. 33x12.5 tires. Wheel spacers and one thin washer on the steering stops were definitely needed to prevent rubbing on the lower (stock) control arms.

Thank You @TRevs! Curious what size wheel spacers did you use?

I have 3 inch lift and ran 33x12.5 on 8 inch +25mm offset rims. They were super aggressive tread and rubbed at full lock and on my guards which are 6 inch bushwhacker flares. They actually stuck out 20-30mm past the guards which is super illegal here. I ended up getting 32x11.5 Maxxis Razer tires on +10mm offset due it it being more legal and I don't need the ground clearance, and it suits my standard gearing. New tires line up perfectly with the edged of the guards and don't rub. Also my 32x11.5 tires measure at 33 inches diameter exactly.
