My pics don’t help a ton, since the rear fender is cut out, but you get some idea ….
Stock height with 31x10.5r15 on OEM 15x6 rims
with Old Man Emu (OME) 2.5”ish lift. Same wheels and tires as above
Now 33x12.50r15 on 15x9 wheels
- disk will fit behind a 15” wheel that has 3.25” backspacing.
-16 seems to have greater variety of sizes available and in many cases are cheaper
Should fit a stock height truck
33s will rub a stock height rear fender
31 will fit stock height, but will look small once the truck is lifted...
