Oooohweeee! 255/80r17

Figgin' love my 255/80/17 E AT3W wildpeaks. I ran the 285/70/17 C loads and these are better in almost every way except maybe looks depending on preference. I personally built my rig light and for utility over looks :tongue:

My biggest gripe with the 285s was the weight and the bad traction in deeper snow / slush. They felt like they wanted to float. These 255s are much better at cutting through and great traction On & Offroad. This is my second winter and have around 20k on them.

Thinking about the 34x10.5s next.

Where was that picture taken? Looks like Grand Staircase National Monument in Utah. I think I was at that exact location a couple years ago. When I was there, the road going onward to the east was massively washed out and I dared not take it, even with the 4Runner capabilities.
 
Any noticeable power loss?

After looking at a tire comparer online I'm thinking about 235/80/17 tires.
The dia is pretty much the same as OEM so power should be unchanged.
I'm not off roading. I'm looking for something that will help the truck track better and be more stable in the wind.
Any improvement in this area with skinnys ?

This one is on Shafer Trail looking back up to where it starts. Driving the uphill direction.

You will notice considerable slugishness going to 285/70s when trying to get going from a stop. The 255/80s alleviate some of that but it is still noticeably different from stock feel, no complaints personally. RPMs will be lower at you top end highway speeds as well which may affect your driving experience depending on how hard you are pushing it (gear hunting).

Its been said 1001 times but for those loosing mpg its important to note you are gaining distance as your circumference is now larger. Ex, Changing from 265/70/17 up to 255/80. If you were at 15 mpg and went down to 14, thats a 6.6% loss in mpg but you are traveling 4.6% farther that the computer and odometer are not accounting for.
 
I'm thinking about going from 285/70-17 to 255/80-17 next time. I really really like my Toyo Open Country AT3s in C rating, but I live in NE Ohio and as someone mentioned earlier, they do seem to want to float quite a bit in snow and slush.

I currently have no rubbing with my Eibach kit. I know manufacturers have slight differences, but overall should I expect any rubbing issues going from the 285s to the 255s?

Thanks, all!
 
Just another opinion on skinnys...

I recently burned through my Wild Peak 285/70-17's that I managed to get 63000 miles out of.

After reading a Road & Track article on the Kenda Klever RT, I chose a set in the rare 33x10.5-17 LT-E size. Walmart had them for $240.00 each.
They have a three ply sidewall and are almost identical in height and 1/2 inch wider than the 255/80-17's.

They use Kenda's R/T tread pattern. I now have 3000ish miles on them including over 1300 miles towing our Airstream Basecamp20X to Big Bend NP and back, along with about 85-95 miles of off-road playtime.
We aired down to 15lb and ran the crap out of the truck and Kenda's.
Cant say enough nice about these tires. they pull out from a stop better than the 285's. The E load range, 3 ply sidewall held up nicely to the low air and after 30 miles of washboard gravel at 35-40 mpg, the tires were only warm to the touch.
SO...are they the be all, end all of off road R/T tires? Doubtful.
but for the $$$ spent, I am very happy with the ride, feel and off road ability of the Kenda Klever R/T.

if you like the toyos so much, you can stick with them but get the 34x10.50 flavor in the c rating too. I am enjoying them on our setup. definitely a different look from the normal 285/70-17 tho. they are taller, so if you regularly go full stuff with suspension, you will rub the inner fender liners. Nothing too bad. I added 1/4" steel to the bump stops to space them down a touch. Basically made big washers.
