As long as you stick with an E load rated tire with a 121 load index or higher, you'll be good to go. I would recommend running the Nitto Dura Grapplers. This is one of the best, if not the best, tire for towing. Click the banner for more information.

We are currenlty running a promotion with $50.00 off any set of 4 wheels. I would be more than happy to set you up with a wheel and tire package if you're interested :thumb:

So will a 275/65R18 fit without any rubbing or torsion cranking on a stock truck? Ive been pulling my hair out trying to figure this one out..

Too close to tell. I show a 265/65R18 will fit without modifications. A 275/65R18 is only slightly taller and slightly wider. With stock wheels you may have to do some minor cranking.

Do you know the offset on your wheels?

Thank you for the information. From your factory set up, the new 18" assembly will extend outwards 38mm (1.5") more. The clearance to the inside will stay exactly the same. I wouldn't consider this to be real aggressive. Without cranking your torsion bars, you may experience some tire rub at full turn.

the size I'm looking at 275/65r18 and I believe the back spacing was 18 mm tires were bf goodrich and the rims were magic line I think I have to look it up. Ok the rims are v-drive 18x9.
