325/60/R20 Goodyear DuraTrac?
 

Alright I've heard these tires kick ass, but have been reading mixed reviews on any diesel truck. Why diesel? Yeah ask the people who reviewed them. To me they sound like jack asses, why would that make a difference? If I'm wrong then correct me. Is anyone having issues running these tires on a f250, f350? Heard they can be kinda sketchy when pulling, but I won't doing too much hauling. Any info from ford drivers would be nice. Thanks!

I run them, but not that size. I love them, and I've had no issues with them. I spent 3 months researching tires on my last deployment...I had lots of free time. I read about weak sidewalls and how screwy they could be. I heard about people being so scared of them they wouldn't let the wife/kid drive the truck, and they wanted to return them. To me, it sounded like an issue of tire pressure. Mine are rated for 65psi, and I run them very close to that. I have never run any tire that close to the max psi. When I first got them, once or twice I noticed what some people called "tread squirm" but only when I was getting on it, and making a turn, like pulling out into fast moving traffic. They do have a deep tread with a lot of blocks, but it was nothing dangerous by any stretch. I've not noticed anything out of the ordinary when towing.

FWIW, my rig weighs 8400lbs, so nobody can convince me my truck wasn't heavy enough to experience issues.

I just got a set in 265/70/17. I read all those reviews too, and at least in a lot of the cases, I'm not sure they were using the E rated tires. Some were, but it seems like in most cases I read they never said whereas the ones that reported good results noted more often they were using the E rated tires. I'm sure a D rated tire would have more problems. Don't quote me on this, but I believe when they first came out a couple years ago they weren't even offered in an E load range.

I only have about 20miles on mine so I can't comment very much, but so far I can't tell a bit of difference (handling wise) between these and the tires they replaced (also E rated). But I haven't towed w/ them yet either, so who knows.

I'm running them in 315/75-16 E
The heaviest I've hauled was 11K on truck axles, plus 7K on trailer axles. Had fronts at 55, rear at 65 psi.
No fears, no concerns. Will definitely run them again!

They do have more compliant sidewalls than most E range tires - they are about the same as my old load range D T/A K0's. That means better ride quality for sure - as well as better traction on and off road. But should also mean they are more prone to sidewall punctures in really harsh off road conditions. Treat them like a D rated tire then.
With the tiny sidewalls of a 60 series, you definitely shouldn't notice any sway or towing issues due to flex.

And the tread compound is MUCH more flexible and stickier than some old fashioned M/T tires. That means far better traction, especially in wet or snow (hence the severe winter service rating), but does mean more tread squirm. I noticed it the first couple times I drove, now I don't.

The biggest downside? They are almost impossible to break loose and spin on dry pavement! Bad if you like to show off, good if you like traction and safety....

Ha yeah thanks. I won't be trying to break loose any time soon on drive pavement. I would throw my old ones on. They're almost slicks anyway. I wanted to run em with 18" rims, but the wheels I really like that are 18s are only 8.5" wide and with 325/65/18 and I don't wanna put 12.5" wide tires on a rim that's only 8.5" wide. I've heard that it Will work, but every person that I've asked about tires, say that they wouldn't recommend it. So I'm just gonna go with the 20s. .....After what size duratrac do the sidewall styles go black. I don't want 35s with outlined white letters lol

My 265/70/17 are black sidewall (BSW) - don't know if they go back to the outlined after that or not. It should say on most any tire website though.

Yeah depending on the site, I've read different things. I'm pretty sure the larger tire has a black wall

My 315/75/R16s are BSW

The side I have out are black... but no idea if the other side has RWL or not...
