Hi Walone,
Tyre pressure "Comfort" setting, you mean the correct pressures? The tyre pressures are designed and tested to maximise grip, stability/safety and economy for the laden weight of the car. Hence why diesel engines cars have higher pressures compared to petrol. The 2 different quoted pressures on the fuel flap
sticker are by far the best to stick to. So if your going on a trip fully loaded with passengers and luggage then increase the pressures and when you get back and it's just you in the car reduce the pressures, simple really. Most importantly; check the pressures regularly as the state of our roads, speed bumps and enthusiastic driving take there toll.
PS: if your car has different size wheels to the ones it was built with (check the
sticker in the boot) then the
sticker in the fuel flap won't have the right pressures unless it specifically quotes the tyre size.
