I have a stock 05 SR5 with rear airbags and the truck currently has 16 inch wheels. I'd like to upgrade to 17s and wanted to see if you though the 275/70/17 BFG KO2s would fit using Pro Comp 51 Series wheels (17x8) with 4.25 inch backspacing. I plan on doing a mild suspension lift in the next year and would like to plan ahead and not be stuck with smaller tires after I do the upgrade.

I'd wait and buy the tires later but the ones I have are dry rotted pretty bad and I want to get out on some trails next month.
