Hey guys, I want some new 17x9 inch wheels. I found some I like and they actually have our crazy lug pattern! BUT... they have 5.71 backspacing and stock rim has 5.5 sooo my question is will i need spacers or will they be ok?

 

Thats hard to tell without measuring it! Keep in mind that (assuming you have 15 inch wheels now) the new ones will be an inch further out (dealing with radius here, not diameter) where any potential contact is concerned, so you're comparing apples to oranges by comparing the two wheels' backspacing.

The easiest way to tell is to build a jig to measure it! Make something that comes out from the hub 8.5 inches and goes back 5.71 inches from that and spin it around the wheel hub and see if it hits anything.
