I have my 06 stx leveled. Have aftermarket 18 inch wheels with +18 offset and they stick out a little from fender. What would be biggest size tire I could get. I called a place and they have a 325-60-18 which is a 33 inch tire. Need help

Very common question. Right at the top of this forum section is a guide on that.

It's got a TON of information in it, you should check it out.

still didnt find anything

There's a PDF file within maybe the last 10-15 pages that lists ALL the trucks that have been posted on that thread. I'm going with 305/65/18 bfg KO's (33.7") in a couple weeks. Stock wheels but should still fit if yours is 4x4. I think problems come in with offsets closer to 0 (assuming 9" wheel).

18" wheels by what width? What's the backspacing? Those are 2 things you need to know in order to find out what you can fit.

You already know the offset and your truck is levelled so you can use some of the sizing in there as a reference.

I was offering that sticky as a suggestion instead of saying "I don't know off the top of my head."
