Applicable range of car tire labeling system in summer replacement, according to the rolling resistance coefficient (RRC) is divided into 5 grades, AAARRC = 6.5, AA6.6 = RRC = 7.7, A7.8 = RRC = 9, B9.1 = RRC = 10.5, C10.6 = RRC = 12; wet skid resistance (G) is divided into 4 grades, al55 = G, B140 = G = 154, C125 = G = 139, D110 = G = 124.

 

Tire rolling resistance and wet skid resistance coefficient below 9 for more than 110 of fuel-efficient tyres.
