2006 wheel and tire ?'s - Diesel Forum

I know that the stock tires are a 265-70-17 and that the stock wheels are 17x7.5 with 6" of backspacing.

I am looking to get the Pro Comp Extreme AT's in a 305-65-17. I was planning on using these wheels, 17x9 with 4.75" of backspacing. Will the tires stick out or will they be tucked in nicely? Any suggestions would be appreciated as I am not set on rim size/BS yet.

The stock 17x7.5s have 5.50" backspacing I believe.

So, the 17x9 with 4.75" backspacing will stick out 2.25" more than your stock wheels......and then with the tires being slightly wider they will stick out a tad bit more.

Any idea where I can find the correct BS for the stock wheels? I have searched here and I have read 5.5 and 6, so what is it?

17x7.5s are 5.50"
The 18x8.0 and 20x8.0 are 5.80"

Hmm... Here is what I have from when I did the figures on the factory wheels...

Thanks PowerStroke. I am still undecided, I'm going to take some measurements tonight. I will post up later with what I measure.
