285/70-17 Studded Duratrac's on a 2005 Dodge Ram 2500 Gasser. About 1500 miles on them so far.
First impression, Noticeably soft sidewall. If I change lanes moderately aggresive above 40 mph the whole truck sways. I aired them up over the recommended pressure on the sidewall. This helped some but it is still noticeable. I do not consider this a good thing and wonder if the center of the tire will wear faster going this route.
On the plus side I find myself driving less aggressively and the ride is smoother.
Noise, quieter than I thought. Hums down the road above 45mph.
I would not consider them loud at all and that's with studs.
Rolling resistance, They are very grippy and don't roll as freely as all terrains I have owned. Lost about 1-2mpg over some bald A/T's
And Lastly...
TRACTION, I literally just road tripped over Kenosha, Hoosier, and Loveland passes in a snowstorm. Zero weight in the back. Roads were snowcovered and icy. Deepest snow on the road was about 3-4" deep. I engaged my 4wd to pass people, these tires work VERY well under these conditions. Best traction I have ever had in a tire. I also went blasting through a few 2-3' drifts up a steep gravel road because well, that's fun too
The studs helped me to completely stop on my icy 15% driveway.
They work very well.
So IMO,
Winter Traction=Excellent.
Noise= Good
Sidewalls= Medium to Poor on the Highway, Great for off road at lower speeds.
