Is there any difference in the 2wd and 4wd rim backspacing? Also, what is the largest tires you can put on a stock 2wd?

IIRC the rims are the same for 2wd as for 4wd... .

You have 315's on a 2wd?



So, i could easily swap my rims and tires out on the new truck?



But i wonder how much more clearance 2500 vs. 3500?





Anyone here know?
