Backspacing and Lug Pattern

When purchasing aftermarket wheels, what backspacing and lug pattern do I need to ask for?

Pattern is 8x170, right?

What about the backspacing.

Probably looking to run a 9 or 10" wheel.

Yep, 8x170mm

You will want to run 4.5" backspacing. You can run 5", but most likely will rub the springs. 4" or less will stick out far and cause clearance issues.

Re: Backspacing and Lug Pattern

Do you want to cover up the tires?


What size tire?
What size suspension lift, if any?

Leveled on the front, so 3.5" max, and 35's, max.

Re: Backspacing and Lug Pattern

Here's my truck back in 02-03.

4" lift, 35/12.50R16.5 on 16.5x9.75s with 4.25-4.5" BackSpace.

As you can see.....with no flares, the tires throw a lot of crap at the truck:

Re: Backspacing and Lug Pattern

I gotcha.

I have a set of Outlaw flares at home, just need to paint them.

What width on those wheels?

Re: Backspacing and Lug Pattern

I think it was gregrob that said once "lifted trucks are GAY..."

Anyway I run 4.5 backspacing on a 10" wheel with 37's... it was the best fit to get them in there...
