Tyre Talk: FAQ

Q. Are there any conditions in which DriveGuard tyres might not travel 50 miles after a puncture?

Factors affecting run-flat or low tyre pressure operating distance include vehicle speed, load, and maneuvring; the amount of inflation pressure loss; the extent of any tyre damage; and ambient temperature. To maximize the distance capability in a run-flat or low pressure condition:

  • Reduce vehicle speed as much as safely and reasonably possible. Do not exceed 50 mph.
  • Avoid abrupt or aggressive acceleration, braking, or cornering manoeuvres as much as safely and reasonably possible; avoid pot holes and other road hazards.
  • Higher vehicle loads (such as with more passengers or cargo) and higher ambient temperatures decrease the distance capability of a DriveGuard tyre in run-flat or low pressure operation.
  • In the case of a delay in the TPMS being triggered (e.g. in the case of a slow loss of tyre pressure), you may have already travelled some kilometres in a run flat condition. We therefore recommend that you proceed to a safe and convenient location for tyre service as soon as possible after the TPMS has been triggered.
