je hebt ongetwijfeld Goodyear banden. Op de site van die firma kwam ik het volgende tegen:
Tread Wear
More Than 100 - Better
100 - Baseline
Less Than 100 - Poorer
The tread wear grade is a comparative rating based on the wear rate of the tyre when tested under controlled conditions on a specified government test track. A tyre graded 200 would wear twice as long on the government test track as one graded 100. Your actual tyre mileage depends upon the conditions of their use and may vary due to driving habits, service practices, differences in road characteristics and climate. Note: Tread wear grades are valid only for comparisons within a manufacturer's product line . They are not valid for comparisons between manufacturers.
Traction
A - Best
B - Intermediate
C - Acceptable
Traction grades represent the tyre's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. The Traction grade is based upon "straight ahead" braking tests; it does not indicate cornering ability.
Temperature
A - Best.
B - Intermediate
C - Acceptable
The temperature grades represent the tyre's resistance to the generation of heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperatures can cause the materials of the tyre to degenerate and thus reduce tyre life. Excessive temperatures can lead to tyre failure.
Het heeft dus te maken met de amerikaanse normering voor banden. Tread Wear staat voor de slijtage (wear) van het loopvlak (Tread) Je banden zijn slijtvaster dan de Amerikaanse regelgeving voorschrijft, maar niet zo slijtvast als de gemiddelde band (die zit rondom de 300 - 400):
TreadWear Grade
Below 200= 15% of Tires
201 - 300= 25% of Tires
301 - 400= 32% of Tires
401 - 500= 20% of Tires
501 - 600= 6% of Tires
above 600= 2% of Tires

Je banden zijn wel redelijk hittebestendig. Ook weer belangrijk voor de levensduur: door hitte kan het materiaal sneller ouder worden (droogtescheuren!).
Wat de DOT-code betreft:: die info heb je al
Zo voldoende info?
