The Michelin Primacy MXM4 is a solid choice for drivers who value comfort and dry grip in a grand touring all-season tire. With comfort and noise scores both at 8, it provides a ride that is smooth and quiet, aligning well with the category's expectations. Its dry grip rating of 8.5 is notably higher than the category average, making it a reliable performer on dry roads. However, the Primacy MXM4's treadwear warranty of 55,000 miles and UTQG rating of 500 are below the category benchmarks, indicating a potentially shorter lifespan. This is a significant consideration for buyers who prioritize longevity, especially when competitors like the General AltiMAX RT45 offer longer warranties. In the grand touring all-season segment, the Primacy MXM4 stands out for its comfort and handling, but those seeking maximum tread life might find better value elsewhere. If you prioritize a quiet and comfortable ride with strong dry grip, this tire is a good fit. However, if your main concern is getting the most miles for your money, consider alternatives with longer warranties.
