The P-Zeros have a wear rating of 220. The all season Scorpion have a wear rating of 520
Copied over from another thread I posted in:
The 3-Season has a tread wear of 220 AA A
The All-Season has a tread wear of 520 A A
Some background info:
UTQG Treadwear Grades are based on actual road use in which the test tire is run in a vehicle convoy along with standardized Course Monitoring Tires. The vehicle repeatedly runs a prescribed 400-mile test loop in West Texas for a total of 7,200 miles. The vehicle can have its alignment set, air pressure checked and tires rotated every 800 miles. The test tire's and the Monitoring Tire's wear are measured during and at the conclusion of the test. The tire manufacturers then assign a Treadwear Grade based on the observed wear rates. The Course Monitoring Tire is assigned a grade and the test tire receives a grade indicating its relative treadwear. A grade of 100 would indicate that the tire tread would last as long as the test tire, 200 would indicate the tread would last twice as long, 300 would indicate three times as long, etc.
So it would be my understanding that if you took the tread wear rating of each tire multiplied by 7200 miles you would get the predicted tire life.
(220/100) x 7200 = 15,840 miles for the 3 Season
(520/100) x 7200 = 37,440 miles for the All Seasons
The numbers seem inline to my observations with my all seasons and from my earlier educated guesses.
