pvr said:I agree, but was surprised the Porsche dealer passed my 8 year old fronts as absolutely fine. For the warranty, the tyre sealant has to be no more than 4 years old but the tyres can be way more. Does help that my tyres never see sunlight of course when not being driven.Scubaregs said:Tyre manufacturers recommend a tyre life of 6/7 years. Tyres harden with age, they may look fine tread wise, but they will not grip anywhere near as well.
Shouldn’t have, pretty sure it's 7 years for Porsche iirc.
