Nexen CP671: what the numbers tell you
At UTQG 400, the CP671 sits in the mid-life performance tier. Tread life will typically run 25,000-40,000 miles on most vehicles before the wear bars are reached. 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 CP671 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.
