Had these for 42500. I can say these tires do give you better gas mileage. The tires put less strain on the engine. Car has a slightly better response time. At times I got 36 miles per gallon on highway. Only rated at 31 on my car. Unbelievable. What's really nice is I have a 17+ gallon tank and it really makes trips to the gas station less frequent. That's a plus for me. What is your time worth. Think about this, I got about 10% better gas mileage than the rated mileage, always. I don't baby my car either. It really will pay for itself. The ride and handling is better than average. Not the quietest tire in the world however for the 300 it's a quiet car anyways. The handling in snow is not a problem for where I live but it is probably its only downside. I never had a problem though a few times I drove in it. I had nail in a sidewall and needed a new tire. I put on new Goodyear's and wow, I felt like I was driving through mud compared to the Michelin. Didn't like them and I will be going back to the Michelin A/S tires soon. Good technology in the Michelin's. I am impressed with that tire. It's not the perfect tire but many will like it and how it improves the response of the car.
Do not buy this tyres. My new Chrysler came with the set on it and after 6 alignments and balancing within 10months the tyre is gone after 16000Kms. While the handling is good it is too much money to be spent on these tyres which did not last more than 16000kms.
