Looking for some insight here. I bought Michelin Defender LTX M/S tires at Costco 2 years ago. There is still a lot of tread left, but every time it rains or the roads are wet, my tires are slippery. I went to Costco today to ask about it, but the technician said there's nothing he can do and suggested it might be an issue with my vehicle. I don't think so—I stay on top of maintenance and just had brand new brakes installed. Has anyone experienced something similar, or does anyone have suggestions?
