Are runflat tyres less comfortable?
Run flat tyres have reinforced sidewalls allowing them support the weight of the vehicle despite a loss of pressure. The tyre is therefore more rigid than a conventional one. In theory, they're less comfortable, but it's not really noticeable.
Are MOE tyres run-flat tyres?
No, they're not run-flat approved.
However, it is possible to drive on MOE tyres without pressure, but their sidewalls are less reinforced than those of run-flat tyres.
Why? This comes from a special request from Mercedes-Benz to equip their cars with tyres that can run flat without compromising on comfort.
Are run-flat tyres heavier?
They're slightly heavier than classic tyres because of the reinforced sidewalls.
Are run-flat tyres suitable for all cars?
No, only approved rims can be fitted with run-flat tyres. On the other hand, can regular tyres be fitted to run-flat rims?
Do cars consume more fuel when fitted with run-flat tyres?
Run-flat tyres are slightly heavier, which should lead to a slight increase in fuel consumption, but this remains theoretical, because in reality, it's difficult to see any differences.
