For the 10.50s you could do a 7 inch wide wheel. You should go 8 wide for the 11.50s 8 wide would be fine for both. (Tire width x 0.66)
Stock wheels are 16x7 with a 29x10.50 tire.
1 inch is 25.4mm
If you go with an 8 inch wide wheel and 0 offset, your inner surface is 13mm (12.7) closer to the engine bay. Therefore a -13mm offset clears the same as stock with a stock width (10.50) tire.
11.50 width tire pushes the rubber 13mm (12.7) closer to the engine bay.
Combine the two changes and you need a 26mm offset to match stock clearance.
Be sure to check the actual width of the tire. My 35x12.50s on my Toyota are 13" wide and I do not know the actual width of the stock tires. The stock tires are said to be too close without a little adjustment, I believe to the steering knuckle.
The best I've found with a108mm (107.95) hub bore was -20mm offset raceline rock crushers so I'll take a look at these. I'm looking for wheel/tire combo as well.
Can we run 15s? This is a great wheel choice if so.
After looking at the numbers and considering that I would like to run a 33x10 tire, I think the best choice for me is
Raceline Rock Crusher Wheel Polished Aluminum 16x8 5x5.5" ( 5x139.7 ) -20mm
If I did the math right this would out me .5" further from the engine. Wish it was 16x7 though
