For those in th emarket for AT tires

[WU7X]

I have a set of AT3's on my 2011 T4R. this morning we had wet, compacted snow on the roads. Maybe even some black ice under that. The AT3's really scared the heck out of me. On accelleration they were sliding the rear end around. Braking wasn't any better. I had to put the rig into 4WD to back it up my slightly inclined driveway.

I have no experience with them in deep snow, mud, etc. but I don't like them in icy conditions. Cooper makes an ATW that is supposed to have 30% better grip, according to a very reliable source.

fortunately, I recently purchased a set of ST/MAXXs (255/80R17) to go along with a 3" OME lift I'm having installed in January. I'll have the centers of those tires siped. Hopefully they will have a lot more grip than these AT3s.

Just my $0.02 worth.

The only thing that I question as a 4x4'er is the two ply on the Cooper AT3's. I always feel better going offroad with a 3 ply tire.

What would be the better choice for a stock 15 SR5 if I were to decide on the AT3s?

P265/70/17
LT265/70/17 C load rating
LT275/70/17 C load rating

The 4Runner is fully stock and is my daily driver. I may only ever tow a very light trailer maybe twice a year. I won't be lifting it any time soon and will maybe take it light off roading once or twice a year also. Mainly want some added traction for wet and light snow/ice covered roads we get in Tennessee.

"Vague on-center feel"...

...with an SFA vehicle...

I lol'd.

When my stock duelers kick the bucket, I'll be looking at the P265/70/17. If those are unavailable, then I'll see if I can snag the LT C load of the same size. I use mine the exact same way you described. If it's good enough for members like [MENTION=66316]1engineer[/MENTION] who actually take their truck off road more than I, then I think it's good enough for someone like me.

Just buy what you're most comfortable with.

EDIT*** Look here! Lots of insight --->AT Tires

If you want an a/t tire I'd look at the Cooper A/TW or Nokian Rotiiva. Getting good snow/ice traction, good wet traction, and something you can drive all year is asking a lot of a tire. Maybe the Nokian WRG3 SUV for a street (non a/t) tire. I think Michelin has some tires that might work also, but can't think of what they are off the top of my head.

I have a similar challenge and still haven't decided if I'm going with one of those or a two sets of tires/wheels.

Arn't load C's a bit light duty for the 4 Runner? I'm pretty sure the stock 265 70R 17's are even load E. I'm new to 4 runners (2010 TE here), but with 4700 LB weight...they are not light vehicles. If you tow something/plan to go offroad my inclination would be to go to at least load D or E. You may experience bounciness or tire sway on turns if they are too light duty.

I'd like to see a test of how reliable and repeatable on-vehicle tire tests are likely to be.

Stock 4runner tires are P rated for passenger car use. My new 275/70/17 BFG KO2 load range E tires are rated to carry 3195 lbs. each at max pressure so 2 of these ties is more than enough to handle the 4runner. Load range C is ideal in my opinion. I had load range C tires on my old 4runner and they seems perfect to me. Load range E is overkill and only use full if you want thicker sidewall for better puncture resistance off road. They are also much heavier.
