general problems of the 2017 GMC Acadia

Tire size is p235/65r18 I purchased these tires in December of 2024. I am concerned that these tires were built without the correct compound to be qualified as an all-season. I have never had tires this bad in snow, even though they are all season brand-new tires with full tread. I immediately bought a set of snow tires for the vehicle. I again tried these tires in snow in November of 2025 after they had roughly 10,000 miles on them, and again found them to be the worst tires in snow that I have ever driven. I am concerned these were a mis-build.

Michelin premier ltx 235/55r20 premature wear first set was replaced 12/11/2019 with 27,952 miles on vehicle. Complaint is the second set checked on 7/23/2023 with 49,122 miles on vehicle or 21,170 miles on tires showing premature wear measuring 6. 1 to 5. 9 /32nds groove depth. Tires are not going to make the 60,000 miles wear rating expected for such an expensive tire. Tires are rotated when vehicle is serviced, alignment was checked before installing new tires.

235/65r18 all 4 tires worn down after 27,000 miles, suppose to have 60,000 mile tread life. Took my Acadia into the dealer for regular oil change and was informed all 4 tires were worn passed the safety margin. He told me there was a service bulletin about the tires but since my warranty had run out there was nothing he could do. He never mentioned the service warranty or that the tires were wearing severly.
