Set of 2 Armstrong Tru-Trac AT 275/55R20 117T XL Tires Fits: 2014-18 Chevrolet Silverado 1500 High Country, 2011-18 GMC Sierra 1500 Denali

I've been running C**per Discoverer AT3's for a decade on my 2006 Ridgeline, but they've been redesigned, and they new design wears very unevenly in the shoulder block area, so I decided to try something different. Seeing that Armstrong is back (I'm an old Armstrong Treadlock tire owner from back in the 80's), I thought I'd give them a try. Street performance, wet and dry, is excellent. There's a tiny bit of AT tire hum, less than expected, and at a much lower frequency than my C**pers. The ride comfort is actually a little better. They did very well in sand (up to maybe 3 - 4 inches deep) with marginal steering fight. And in a water crossing with a mud/sand/clay bottom (hard, but slippery) they did better than the C**pers - I think I'd have gotten stuck in one of the holes on the old tires, especially since we got a little hung up on an underwater object (probably a stump or rock). All testing so far was at normal street pressure (35PSI), as I wanted to see how my Ridgeline would perform in an evolving situation, where I might have to do some light off roading with no notice. The actual tread width is a little less than the C**pers, but that doesn't seem to be a negative - the sidewalls balloon out a bit more, so that the overall width is the same, and that shape may actually enhance steering in sand and mud. Overall, I'd say these may be the best value on the market today - not just for AT tires, but across their entire lineup. If they made tires for autocrossing, I'd try those next!
