Tire Requirements
A - Wet Braking Behavior
B - Comfort
C - Steering Precision
D - Driving Stability
E - Tire Weight
F - Service Life Expectancy
G - Rolling Resistance
H - Hydroplaning
The pie chart represents the tire's performance. It shows how the extent of the demands A through H could be distributed in tire construction and rubber compound.
The improvement of one characteristic leads to the worsening of another one.
Example:
The improvement of wet braking behavior -A- leads to losses in comfort -B-, rolling resistance -G- and service life expectancy -F-.
The service life expectancy of car tires depends not only on the rubber compound and the tire construction. The operating conditions, circumstances specific to the vehicle and the driving style all have a strong influence on the tire's service life.
With modern vehicles and appropriate engines, especially gentle and economical but also extremely sporty driving is possible. Service life of 5, 000 to 40, 000 km (3, 100 to 25, 000 miles) and even more is possible.
Driving style is the decisive influencing factor on the life of the tires.
