After five years and 27.5k miles, I still have the original Michelin Pilot Sports on my OEM ZHP wheels with the 235/40 front 255/35 standard staggered fitments. They still have well over half the tread left, are wearing evenly, and are nowhere near having to be replaced. I do run them at very high pressure: 37 psi front, 43 psi rear. Is anyone else getting the same kind of wear out of their Pilot Sports? I expected them to be completely shot at 20k miles.

They should last a long time if you have the "key" things all worked out. Like the allignment on all the wheels, if they are alligned good the tires are gonna last for a very long time. Tirepressure will help a bit, bot mostly with driving more economical with higher pressure.

I usualy run up about 43 to 47psi (3.0 - 3.2bars) of pressure on all my cars which has 18" tires or bigger. On 17's i usualy run just a tad less, depending on what the car weighs..

Tires can last up to twice that if you are really enthusiastic about everything being setup correct and that you ofcourse only drive economical and isn't wearing the tires with hard driving.

However, they do need to be replaced because of age.

I asked the service tech at my dealer and an independent service tech about the age thing, and they said they were still good to go. I've noticed no change in handling or road noise, but I will most definitely bring the age thing up when I get a PPI next week.

BTW, if I do decide to turn the car into my leasing company instead of buying it, could they charge me for a new set of tires just because mine are five years old? The provision in the lease states "wear and tear" and these tires will easily pass a State Safety Inspection.

Then they must be very very old if they must be changed due to age.
Tires with age that is still maintained or stored correct is nothing wrong with. Never heard a tireguy say that age is a problem really and haven't noticed it myself either..

The only "age" problem is when they show cracks everywhere, and that takes a loong time until they do that.

Some tire manufacturers recommend replacing tires after 4 years from the time of manufacturing (not from when you put them on). Some argue that stored tires deteriorate faster. Others say 10+ years is acceptable for a tire life.
In any case, 5 years is not too long as long as those tires were not manufacturer in the 90s.

And OP, you must drive very conservatively. I have yet to hear of anyone who drives hard getting >20-25k on their rears on any BMW.

I have Steptronic, so that no doubt contributes to the longevity of the rears. I only drive "hard" on occasion; I would like to keep the car in meticulous stock trim for the next ten years because to me, it's a classic, so I pamper it.

Most of the time, it's just a very fun daily driver nowadays. At any rate, when the car was still under warranty and I took it in for Inspection 1 at 25.5k, my service advisor said that he had NEVER seen BMW rears that looked like mine after that many miles. I agree, it's strange, which is why I posted about it.

Yeah I would have guessed a ZHP would be driven hard. Some would say that is what they are meant for, not to be babied. But then I can't fault you for wanting to keep a car in good condition for a long time. Kudos to you for having the discipline to do so. No way I can do that.
