Sumitomo Sumitomo ST788E Commercial: what the numbers tell you
Manufacturer treadwear data for the Sumitomo ST788E Commercial 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 winter tire built for the truck-suv segment, the Sumitomo ST788E Commercial 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.
