Nitto ridge grappler: what the numbers tell you

The Ridge Grappler'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. No mileage warranty is published for this tire, which is typical for performance summer and track-day rubber where the manufacturer doesn't make wear-life claims.

Cabin noise data for this tire is not published by the manufacturer. As a general tire built for the passenger segment, the Ridge Grappler 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.
