Volkswagen Polo Service & Repair Manual: Tire Service Life, Influences
| The following factors influence the service life of a tire
in varying degrees. |
| Exterior temperature/climate |
| Dynamic toe and camber values |

accessories which have not been approved by the vehicle
manufacturer are used, wheel alignments which deviate from the
