These came factory on my '09 Chevy 4x4. I admit I don't rotate as I should however GM needs to rethink their pressure ratings. The back tires at 70 psi is way too much. My rear tires wore incredibly fast down the center of the tread. Once that started happening I backed off the presuure about 8 lbs. I always get the OnStar report every month saying they are low but GM isn't providing free tires. The front on the other hand at 45,000 miles look like they still have another 45,000 of life in them.
I figure with the rear replacements by the time they wear down again they will have evened up and all four will be due for a change.
I think the tires are somewhat noisy. I have the LTZ model so even with the extra sound insulation they still drone at highway speeds. Other than that they are average in everything, snow rain, mud. They are a high priced tire but I won't switch until all four need rplacing at the same time.
