I'm sure you can get aftermarket 17" wheels with a 5 on 4.5 bolt pattern. Wouldn't know why since 17" rubber is crazy expensive.
But I kinda doubt that you will find a stock 17" wheel on a pickup that is going to be a 5 on 4.5 much less have a 3.75" backspacing to work on a YJ. Most of the OEM wheels that are 17" come from either a 6 or 8 bolt lug pattern.
'87 YJ, 4.2L built and bored, 8.5" of lift, 8.8 rear, AX15/NP 231, Tom Woods drive shafts, Flat fenders, 12,000LB winch, Custom bumpers, Rattle can paint job. Never completed...
The reason why I want them is cuz my friend works at a tire shop and everyone who has 33--15 run them till they die then he gets them bit 17 s come in used with 50% tread every day he has 7 pairs of mud terrain already for free. Plus I don't have the money to buy a new set of tires for my rig so I'm looking for stock rims I can find at a junkyard for cheep and get all kinds of tires to last me through collage
