17x7 wheels question

what backspace and bore do i need to make them tuck
any help would be great
thanks kevin

the over all size of a rim isnt the prob..its just the backspaceing..and a good offset is in my opinion a +38 on, i have 4x4 finders and im runin caddies with a +32 and they rub the bed sides, a +38 would be just right

Caddies are 7.5" with a +31...so if he was running a 7" wheel with the same offset he'd have a 1/4" more clearance from the fender. That would probably tuck just fine.

Does anyone know how much wider 4x4 sheet metal is compared to the 2wd sheet metal? 85-93

Not sure Baha, I would have to go dig my old 2wd fender out of the weeds that have overgrown it to measure. lol
