The Pilot MXM4 tires came as OEM on my 2012 Dodge Challenger SXT (6-cylinder). At 42,000 miles they failed inspection. These tires were horrible in the rain. They easily lost traction on wet surfaces, even when brand new. Horrible tires. Just ordered replacement Cooper CS-5 Ultra Touring -- all the reviews indicate these tires are excellent on wet surfaces, handle well and are quiet.
I can't understand how these people are saying this tire is bad in snow. I have these on a Challenger and had zero problems in snow. Overall these tires are doing extremely well. Highly recommend them.
