Pilot sports, how old before they deteriorate ?.

I've run Pilot Sports to about 7 years without the slightest problem either in terms of physical condition or apparent grip.
This idea you'll crash on any tyre more than a few years old is laughable. What's more, Pilot Sports are a particularly high quality tyre in the first place.
How wrong can you be? There are well publicised cases of multi million dollar/£ claims made due to fatalities caused by fitting old tyres that subsequently failed. Just last year, one such involved a Michelin tyre. Not for the first time. This idea you'll crash on any tyre more than a few years old is laughable. What's more, Pilot Sports are a particularly high quality tyre in the first place.
Only a real idiot would use a tyre more than 6/7 years old, especially on a performance car, and a close eye should be kept on any more than 3 or 4 years old. Preferably a trained eye.
Crazy to think a tyre can perish before it's worn out and there's several in this thread that it happens to. Surely the answer is just use the car, it's what it's for and does it the power of good in many ways.
If you can't do this then I'd suggest getting Pirelli p-zero rosso if they come in your size, they are very good but wear out much quicker, slightly better than the pilot sport overall I'd say but I can't use them as they wear out too quickly so prefer the MPS

I generally wear out tires long before the age limit,especially on the Porsches. However,my personal idiot light came on with my wife's 2003 SL 500,which was bought new and lightly used (18000 miles,all easy). I was driving it in Arizona at about 70 mph when the rear tire blew completely. Luckily no car damage. However, the tire store did raise an eyebrow at the age of the rubber.
I had earlier said to my wife we should change the visually perfect tires for age reasons. Will not repeat my mistake.

As I understand it one of the key issues is that they can deteriorate internally and result in them delaminating, with the outside tread section separating from the inner portion of the tyre while you are driving at speed, resulting in a blowout. Because the issue is internal, you won't necessarily see any problem or experience a reduction in grip before it happens. As mentioned above, 6 years seems to be the generally accepted age limit.This idea you'll crash on any tyre more than a few years old is laughable.

It's a fair weather car so 3k annually is as much as it does, bearing that in mind something that lasts 15k would make sense. I wish my bike tyres lasted that long, 3k and they're worn out If you can't do this then I'd suggest getting Pirelli p-zero rosso if they come in your size, they are very good but wear out much quicker, slightly better than the pilot sport overall I'd say but I can't use them as they wear out too quickly so prefer the MPS

. In the future I'll be checking manufacturing dates before I have tyres fitted.Edited by blade7 on Sunday 7th April 17:22

I've run a GT3 on PS approx 6 years old. The car was a death trap.This idea you'll crash on any tyre more than a few years old is laughable. What's more, Pilot Sports are a particularly high quality tyre in the first place.
Admittedly this was in a hot climate in which the tyres would have been subject to extreme conditions. Nevertheless it was a clear demonstration that rubber has a finite life.

In which case I've got £50 says there are millions of tyres over that age in regular use which haven't thrown their owners into a ditch. This is just twaddle put about by the "holier than thou" fraternity of motoring pub bores. A tyre in a cool, dark garage isn't going to come to much harm.By the way, have you checked the life expectancy of your air bags recently?

Wanna buy a couple of 10 year old part worn Pilot Sports for your Boxster, spent a lot of time in a cool, dark garage.Unfortunately over the last 25ish years I have had to change blow out tyres that have delaminated due to age. With no sign of other issues that could be seen by the owner these tyres have let go. I'm not saying its a daily occurrence but its also not unheard of either. Only the owner of the car can asses what they think their safety is worth.

Anyone involved in racing will tell you how short the optimum tyre life can be. In road use, the tyres progressively degrade, so it may not be that noticable, but on a performance car, 5 years would see them getting to their 'use by' date. Tread depth is only one factor.

And you're right, a tyre kept for years in a cool, dark garage isn't going to come to too much harm. The problem comes when you put it on a car and use it.
As for the fraternity of motoring pub bores, after 25 years in the more technical end of the tyre business, I would not class myself as such, but if you think you know better, carry on.

Only doing 2-3k a year means they go off with loads of tread left
