would these fit my stock 2000 zr2? goodyear wrangler mt/r tires 31x10.5x15 on cragar d window rims 15x8 with 4"backspacing. Bolt pattern is 5x4.5

 

The tires will...the rims wont. Chevy bolt pattern is 5x4.75.

The MT/Rs though are jeep tires...and I thinkin 5x4.5 is the jeep pattern...hrm..craigslist ad?

 

Get wheel adapters, from 5x4.75 to the 5x 4.5and my jeep rims are 5 on 5, so they he might not have gotten rims ment for a jeep.

 

Haha oh ok...wasn't sure. Its just every lifted jeep around Raleigh seems like they're rocking MT/Rs. Nothing wrong with that...just noting

But to mount adapters, they also are spacers right? So with 4' of backspacing on the rim, then whatever is from the spacer...that might get a little wide right?

 

If the OP misstated the bolt pattern, they would fit but you would more than likely be rubbing on the flarelets at the least. Ask me how I know.

And MT/R's are some pretty damn good tires to boot.
