    Most manufacturers will list the rim size on their website for their tires. 8"-10" is the most common recommended range with the 12.5" wide tires. So an 8" rim is fine for a 35x12.5. I wouldnt go bigger than 35. the 1500's typically dont like bigger than that on suspension parts.

    Might depend on how close the shop looks. but 315's are 12.5 and most manufacturers list an 8" as fine so I would say you are good since most shops will just figure the standard range is 8-10. Heck I had 315's on stock 6.5 wide rims for 1 1/2 years (but no most major shops wont install that size on 6.5's:lol:).

    I hate to tell you this but the stock 17's are only 7.5" wide...18's are 8" wide. I wouldn't feel real good about a 12.5" tire on those but you may be fine.

    Just for reference:
    Factory backspacing:
    17x7.5=
    +31mm offset(5.5" bs)
    18x8= +31mm offset(5.7" bs)
    20x8.5= +31mm offset(5.9" bs)
