Monitor Technology

The RTM (Replacement Tire Monitor) provides the user with a warning when the tyre is worn and has to be replaced. The inscription “Replacement Tire Monitor” shows three times on the circumferential rib of the new tyre. Just before the tread reaches the minimum tread depth indicated by the TWI (Tread Wear Indicator bars), the inscription will change to “Replace Tire”.

• The VAI (Visual Alignment Indicator) allows the user to check wheel misalignment to avoid irregular wear of the tires. The VAI is represented three times in the circumference of the tire by two additional sipes (1.6mm  tread depth) on the opposite shoulder blocks of the tire. If the sipes of the VAI wear off differently (one side more than the other for example), it means that there is potential misalignment of the wheels.
• This assists the consumer in minimising the chance of premature tire wear whilst providing you with a customer service and wheel alignment sales opportunity.
