Driving style |
I. Steady driving without deceleration or acceleration |
Example: |
Speed (km/h) | Wheel slip | Wear |
100 | 1 | 1 |
180 | 3 | 9 |
II. Braking (driving style) |
Most wear is caused during braking. |
Example: Braking from a speed of 50 km/h |
Braking distance (m) | Deceleration (m/s2) → Remark | Wheel slip | Wear |
Vehicle allowed to roll to a stop | 0 | 0 | |
100 | 0.1 x g | 4 | 1 |
50 | 0.2 x g | 8 | 4 |
12,5 | 0.4 x g → Remark | 32 | 2000 - 3000 |
1) | g = Freefall acceleration: 9.81 m/s2 |
2) | A deceleration of 0.4 x g corresponds to heavy braking. |
III. Acceleration (driving style) |
Slip caused when driving off gently is approximately the same as that caused when driving at a constant speed of 100 km/h. |
Example: |
Wheel slip | Wear | |
Driving off gently | 1 - 2 | 1 |
Driving off normally | 7 - 8 | 5 |
Driving off with wheels spinning | 20 or more | 100 - 200 |
IV. Driving through curves (driving style) |
A »sporty« driving style and driving at higher speeds also cause greater wear when driving through corners. |
In practice, this means that wear is increased 16-fold when the cornering speed is doubled. This is the price that has to be paid for going faster. |
Example: Driving through a curve with a radius of 150 m |
Speed (km/h) | Lateral acceleration (m/s2) → Remark | Wear |
50 | 1 = 0.13 x g | 1 |
80 | 2.5 = 0.33 x g | 6,5 |
100 | 4 = 0.53 x g | 16 |
3) | g = gravitational acceleration: 9.81 m/s2 |
