Re: tire size

.

I'm no tire wiz but seems they didn't really do the right thing for you. Wouldn't a 265/70/15 have been a better attempt? I used to run 275/??/15 on my stock 68.

Maybe what they put on was all they had in stock?

EDIT: I'm currently look at tires as well and can tell you I wish I was buying 15s: 4 choices on tirerack between 488 and 540 shipped.

Re: tire size

Ether or a tire bead blaster will seat those tires real fast.

Re: tire size

I would go to a different tire store next time. Both tires are 255 so it should make little difference in seating. But, in any case 10" is way to wide for a 255 tire. You need a wider tire or a narrower rim.

If you want to keep your rims, see if you can fit a 275 or 285/60/15.

You have probably already done the math but the 255-70 has a 1/2 inch sidewall difference so the overall height is 29 inches vs 28 inches.
When I was running 15 inch wheels I ran a couple different sizes. I did run a 275-60 15. That one had plenty of width and sidewall. It fit my truck well on the front and rear. That is the last ones I ran and would probably do that again based on 15 inch wheel.

Re: tire size

Change your wheels to some 8's. One of the biggest mistakes people make IMO with the stance/look of these trucks is 15x10 wheels in the front. They just stick out too far. The taller tire of the 70 series and the narrower 8" rim will make your truck look better IMO.

But 17's the best mod I've done on my truck.
