I have been told the biggest I can go on the factory rim is 285 65 18? Today someone told me a 33 12.50 18 will fit. Any opinions?

 

i had a 285 65 18 on pro comp 7005 rims with 5" a BS with minor rubbing. dont know how much this helps you since you want to use stock wheels.

 

I have a 2.5 inch leveling lift and I've got 325's on 18 inch rims. Little bit of rub but no big deal.

 

my 06 can fit 285/70/17's easily, maybe a 295/305 if I wanted to push it.
I think you can go 285 easily.

You need to stick around the 33" range on diameter, but you could get away with up to a 11.5-12.5 wide tire. I personally think something like a 295/65/18 would look great, Goodyear duratracks come in that size, basically a 33x12, but thats about as big as i would try, expect some potential rubbing there. Something around a 33 x 11.5 would be the best all around fit.

 

Are they mounted on factory wheels? Got any pics? I found a good deal on some 325-65-18's and have a leveled 2WD. I'd hate to pass these up if I could get them to fit.

 

I highly recommend not putting that wide of a tire on an OEM 7.5 wheel.

 

Good point, I didn't about that.
