I should update my original feelings on these tires.
I installed the A/T3W's in 265/70/17 (SL) at the beginning of October '18 on the stock TRD-OR wheels; my truck at approximately 1,100 miles on it at that point. Through a number of "wheeling" trips, countless road trips, daily driving, and plenty of dirt/gravel (to include the 1,000mi Kentucky Adventure Tour) these tires did everything they were asked to and much more (except once). The "except once" was Kentucky quicksand-like clay/mud on the DBBB where the traction boards and a bit of digging were required to get us out.
After 33,900 miles of abuse they've been retired, not because of an issue, nor because of worn tread. They've been retired because a new set of 255/80/17 Wildpeak A/T3W's have been installed on a fresh set of wheels.
They were rotated at roughly 5,000mi intervals, however, did get a bit louder around the 25,000mi mark. For the entirety of their on-road life they were left at 35psi, which seemed to be the perfect mix of fuel economy and tire wear, while never leaving me wishing for more traction. Even on the KAT we left them at street pressure with no issues. "Wheeling" trips would get aired down to about 22-24psi, but I'm not really sure that made any substantial differences. They still have plenty of tread left (I'll measure next week when I put them up for sale w/ my original wheels) and would probably have lasted another 20,000 miles or so.
Now for the new stuff! I went with 255/80/17, which, when the FedEx guy delivered them, caused me to check each tire's sidewall at least twice. These things looked SKINNY! Un-mounted they looked almost worryingly narrower than my 265s. They were mounted on a set of 17x8 Level 8 MK6 wheels (ET 0 for those who care). My local shop that was mounting them did have a bit of an issue getting the 255s to seat on the 8" wheels correctly, but in the mounter's own words "I've got the trick now" (it involved using a Cheetah). I think there were no fewer than 7 or 8 times that he reminded me that a 285 would fit fine on the wheel.
The switch from a 265/70 SL tire to the 255/80 E-rated tire is definitely noticeable to me. The steering is slightly heavier and sharp bumps on the roadway/potholes are felt slightly more. Given the extra sidewall height, there's definitely no extra cushioning that was gained. With that being said, I'm not deterred or unhappy about how the tires feel at all.
Since they are new (about 750 miles on them so far) they are definitely quieter than the off-going Wildpeaks, enough so that my need for the ECGS bushing was solidified (and that arrived yesterday).
In dry/wet conditions I can't say that the driving/traction feel has changed at all, maybe a bit more "roll" on long sweeping cloverleaf ramps, but I'll openly admit that I drive them like I'm still driving something prepped for a track day (nearly all my previous vehicles) instead of a lifted 3-ton SUV. My last two tanks were also quite different in driving environment/style than my norm so the fuel economy hit is still to be determined, if I were to guess, maybe somewhere in the .7-1mpg range?
Also FWIW, I did have to trim the passenger side fender liner (ahead of the tire) as I was getting rubbing at full lock in reverse.
And if you've made it this far, why are you still reading? I truly didn't plan on writing a novel when I started this post
Wow, awesome detailed write-up/comparison - thanks!
