Seems they're also available in 285/75/17, research is supposed to make decisions easier not harder.

Yes, there are larger sizes, but once you go past 285/70 you lose the ability to buy a P rated version which is what our trucks come with. So the 315/70 and 285/75 sizes are LT rated and they are HEAVY...close to or above 70 lbs. each. You can kiss your fuel economy, braking, and acceleration goodbye.

I had a 315/70/17 Duratracs on for a while and with the ecoboost it ran like crap. Literally a 2-3 second lag time in acceleration. Went to a 275/60/20 and it ran like a champ again. I'm going to go to a 275/65/20 or 285/65/20 at some point, but I'm going to buy a tuner first to be able to account for the bigger tires.

Those are the lightest 315/70/17 on the market @ 61 lbs.

They may be the lightest but the 35" tire with my gearing made it run like a tired dog.

To the guys talking about change in mpgs: Are you calculating for speedo error? I see some saying a loss of x.x mpgs but don't know if you are comparing to the same size tire...

Spiky

I think that's the point. Any other 35 would be worse.

anybody had these in significant snow, yet?

ShiverMeTimbers

haven't had mine in snow yet. But they're great in cold wet weather.

Anyone running the Wildpeaks in the 35x12.5x20 flavor?
