Incorrect tyre pressure - in particular, tyres that are under-inflated - can have a negative impact in many ways. Improper tyre inflation can:
- Reduce road-holding
- Cause irregular wear
- Damage the tyre internally
- Result in tyre failure
- Cause the tyre to overheat
- Shorten the service life of the tyre.
There are certain factors, such as overloading and excessive cornering speed, that will cause further damage to the tyre and, ultimately, result in tyre failure.
