Specifications
MICHELIN PILOT SPORT 4
MICHELIN PILOT SPORT 4 255/40R18 99Y XL RunFlat — quality Summer tyre from MICHELIN. Reliable grip, stability and durability for everyday driving across all conditions.
How fuel-efficient is this tyre?
Efficient, just shy of the top. The MICHELIN PILOT SPORT 4 carries a B rating, the second band on the EU scale. Rolling resistance is still low, and in normal driving the gap from a class A tyre is small enough that you'd barely notice it at the pump.
How well does this tyre grip in the wet?
Strong. The MICHELIN PILOT SPORT 4 carries a B rating, one step below the top. Wet braking is still short and dependable — the difference from a class A tyre is small and only really shows up in hard braking on soaked roads. For everyday driving in mixed weather it's plenty.
How much road noise does this tyre make?
Average. The MICHELIN PILOT SPORT 4 measures 71 dB, a typical figure for a modern car tyre. Road noise is there on coarse surfaces but stays within normal, comfortable bounds.
Are these tyres reinforced?
Yes. The MICHELIN PILOT SPORT 4 carries the XL (Extra Load) marking, which means a stronger casing that takes higher pressures and carries more weight than a standard tyre of the same size. That suits heavier cars, fully loaded driving, vans, and EVs, which run heavier because of their battery packs. To get the full benefit, set the higher pressure the XL rating allows.
Can I keep driving if these tyres lose pressure?
Yes, for a short distance. The MICHELIN PILOT SPORT 4 is a run-flat tyre, marked RunFlat with reinforced sidewalls that hold the car's weight even with no air in the tyre. After a puncture you can usually carry on for around 80 km at up to 80 km/h to reach a garage, instead of changing a wheel at the roadside. Run-flats should only go on a car designed for them, ideally one with a tyre-pressure monitoring system.
MICHELIN is a premium class manufacturer offering solid-quality tyres with a good balance of price and durability.
