I would also be interested to know if anyone got a satisfactory answer on this issue. I have Goodyear SR-A’s on my new 2018 Denali truck that had also had me paying $200 extra for “all-terrain” tires. From everything I have read the SR-A’s are just plain crap, and OEM on most of these trucks. And nowhere are they rated as an “all-terrain” tire! Tire Rack has them in the “Highway, All-season” category, one of the milder tread type categories they have. They don’t belong on a top of the line truck, and they certainly don’t have any basis for charging customers EXTRA for something they are not getting! We PAID for “all-terrain” tires and didn’t get them! I paid extra for a sunroof, and would be pretty pissed if it just wasn’t there! I paid for the upgraded tires, but I don’t have them! I realize it’s an older post by now but hoping someone has an update/more info, etc. Thanks.
