Mastercraft courser AXT 245/70R17: what the numbers tell you
Manufacturer treadwear data for the Courser AXT 245/70R17 is not publicly listed. This is common for OEM-only or track-day tires that don't carry a US treadwear warranty. 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 Courser AXT 245/70R17 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.
The Mastercraft Courser AXT 245/70R17 has been part of Mastercraft's catalog since its introduction, and remains a current-production model.
