Yet Another Tire Size Question - Tallest Tires?

Just painted my stock wheels and am looking to pick up some more aggressive tires. Want to keep the stock wheels and go with the tallest tire I can for ground clearance. I know there are some folks running 265/75/16, but it sounds like they won't clear the KYB struts without spacers or without changing wheels.

 

Sounds like I can run a 245/75 on the stock wheels, but I would like to go taller if possible. The expo guys all talk about the 235/85s as performing well offroad and still handling well on road without alot of added drag on pavement (less loss in mpg), and I would gladly run em if they would clear the struts. Have been looking at the Duratracs and the Hankook MTs. Both are AT/MT tweeners that are said to be more aggressive than typical ATs but run a little smoother and quieter on the pavement than typical MTs.

 

There are a couple pics here of a truck with 235/85 Duratrac ATs...

Here is a review of the Hankooks...

Some comparison numbers for the Duratrac from TireRack website...

245/75/16 = height - 30.5, tire body width - 9.8, tread width - 7.5

265/75/16 = height - 31.7, tire body width - 10.5, tread width - 8.5

235/85/16 = height - 31.7, tire body width - 9.3, tread width - 7.7

 

The 235/85 is the same height as the 265/75 and my hope is that the 235 will clear the strut without the need for spacers or a wheel swap.

 

- Has anyone tried this size on stock wheels?

- For those of you that have tried 265s on stock wheels - was there any space between the tire and the strut??

- When I upsized on other trucks there was always a loss in power with the larger diameter tires and the AT would short shift. How much of lag are you feeling with the larger tires?

With stock rims, the 245/75/16's are going to be your max, but try a test fit to be sure. I ran Bridgestone Dueler AT Revos 31x10.5x15 (actual height of tire 30.5, tread width 8.1, sidewall width 10.9) and the tread was within less than an inch of the bottom of the strut. The majority of the inner lug pattern was under the spring perch. Just make sure there is a little room to allow rocks caught in the tread to clear. I had a few gouges in the bottom of the spring perch running the 31's.

 

32's tend to be the max with offset rims, 31" for factory.
