Group1 recommend to change tyres at 3mm of tread (legal limit is 1.6mm)
How to find the tyre information:
For runflat tyres, the different brands use different names for their runflat technologies:
- Bridgestone: RFT – Run Flat Tyre
- Continental: SSR – Self Supporting Run-flat
- Dunlop: DSST – Dunlop Self Supporting Tyre
- Goodyear: EMT – Extended Mobility Tyre
- Michelin: ZP – Zero Pressure
- Pirelli: Euforia – Run-flat System Component
Runflat tyres can be driven on with no pressure for up to 50 miles at a maximum speed of 50mph.
Runflat tyres can NOT be repaired if punctured.
We will only fit star rated tyres to vehicles.
Tyre labelling Legislation:
Fuel efficiency (rolling resistance)
- The label shows the tyre’s fuel efficiency on a sliding scale from A (best) to G (worst).
- The difference between best and worst can be as much as 7.5% for cars.
Wet grip
- Wet grip performance is measured under controlled conditions and rated from A (best) to G (worst).
- The difference in stopping distance between each grade will be one or two car lengths when braking from 50mph.
- Overall the difference in braking distance between best and worst (A to G) will be around 30%.
Noise
- A single ‘sound wave’ shows that the tyre is relatively quiet
- Three ‘sound waves’ shows that the tyre is relatively noisy
