Throwback Thursday: Safety tyre discount; explosion risk

Throwback Thursday

Insurance Post’s Throwback Thursday steps back in time to August 1975 to remind you what was going on this week in insurance history, when safer wheels could slash your motor insurance premiums and concerns were raised about foam.

14 August 1975: Safety tyre discount

The Stewart Wrightson Group offered a 15% discount on insurance premiums to motorists that fitted the Avon Safety Wheel.

The Fire Research Station stated an explosion risk may exist when the flammable smoke and vapours from the smouldering of large quantities of foamed rubber are confined in an enclosed space.
