Pilot Sport All Season 4

Michelin Pilot Sport All Season 4: what the numbers tell you

The Pilot Sport All Season 4's UTQG treadwear rating of 500 puts it in the long-wear class. Its compound is engineered for life over outright grip, which is appropriate for an everyday touring tire. The 45,000-mile warranty is one of the most concrete data points for a tire. It is the manufacturer's own statement of compound durability under normal use. Warranty replacement is typically prorated, so it will not fully offset the cost of a new tire, but the warranty length is a reasonable expectation of useful tread life.

Cabin noise of 69 dB (EU label) is on the quieter end of the segment. This tire will fade into the background at highway speeds. As a all-season tire built for the performance segment, the Pilot Sport All Season 4 is positioned against direct rivals within the same category. Comparing it to a tire in a different category (e.g. summer vs all-season) makes the spec sheet misleading because the design targets are not the same.

Grand-touring all-season tire that targets summer-tire dry grip while keeping useful winter traction down to about 20°F.
