Do tyres have a lifetime after which they can be unsafe?
I am finally going to get around to selling my 350SE alloys, now the car is sadly long since gone. They have P6000 tyres on them, which were put on by a previous owner and I think the tyres are at least 13 years old, based on the car not having those alloys on in a photo at Le Mans in sprint from March 2000.
I am concerned that if I sell them with the tyres, they may be unsafe and someone will use them. Is it prudent to bin the tyres? Visually they look fine.

6 years is the recommended life of tyres. After that they can go hard, crack and just generally deteriorate.
13 y.o tyres are fit for playground swings only.

The week and year of manufacture of the tyre is always marked on the sidewall. A tyre marked 2501 was manufactured in week 25 of 2001. Manufacturers usually also mark tyres to show which factory they were made in, so they can trace where and when a faulty tyre was made.
Where do I find this on my tyre?
Find a string of numbers & letters close to the tyres bead usually starting with DOT at the end you will find the 3 or 4 numbers relating to your tyres age. If your tyres have just 3 numbers they will have been made pre- 2000 and even if they still have plenty of tread on them we suggest changing as they may be subject to rubber corrosion.

I understood that sunlight caused tyres to deteriorate so if stored in the dark they would last longer.
It's not just sunlight, but ozone that's the enemy - the following from Wikkipedia:Ozone cracking used to be a serious problem in car tires for example, but the problem is now seen only in very old tires. On the other hand, many critical products like gaskets and O-rings may be attacked by ozone produced within compressed air systems. Fuel lines are often made from reinforced rubber tubing and may also be susceptible to attack, especially within engine compartments where low levels of ozone are produced from electrical equipment. Storing rubber products in close proximity to DC electric motors can accelerate the rate at which ozone cracking occurs. The commutator of the motor creates sparks which in turn produce ozone.
Tyres 6/7 years old, them you should scrap them, especially with the power potentials TVRs have.........someone doesn't want to loose a loved one??

I had Goodyear nct 2's on my lattice alloys till I recently changed. The wheels, had no problems whatsoever and apparently the nct 2 tread pattern was from the 1980's. 6 years then bin em sounds a lot premature of you ask me. The tyres I have on the daily hack are way older than that.

The six year suggestion is not just opinion on here if you look on the links in my post or just do a Google search you'll see that 6 years is the recommended age to replace them. But if you value a few tyres over the potential risks to yourself, your family and your car then just keep them.Dix
My pushbike tyres never seem to last more than a year or so before the grip goes.

6 years for a tyre, there must be a fair few crazy fools risking their lives every time they go out then as most new tyres are on the car a fair bit longer than 6 years. As for age my tyre fitter says if they ain't in sunlight constant and no obvious damage they will be fine. Only change them every six years if you have more money than sense then started laughing His words not mine. I risk my familys well being every time I venture on the roads due to all the lunatic drivers on there anyway. Google is not the all seeing Oracle some people think it is and common sense is sometimes a better guideline.My pushbike tyres never seem to last more than a year or so before the grip goes.

the problem with the internet is anybody can post on it- and I am sure we have all met some nutters. Scary huh.
besides who stands to make out of the six year claim................... the people that make and fit tyres.
I must be doing something wrong as I never had a set of tyres last more than two years!

It's not that long ago you were lucky if a CAR lasted more than 6 years...before turning to a pile of rust.

Audi A3 for sale..
Low mileage..
Good reliable car..
Needs a little TLC..
No tax or MOT, Hence the price..
The car has sat for a short time but the tyres are still in good condition.
I'd be inclined to agree with the 6 year rule, but have in the past used "old" tyres on a classic car.
I had one set of tyres on an old XJ6 that were fine (or seemed so) for normal driving until one day I swung onto a forecourt a bit quick and because the side walls were not as strong as they should have been the tyre came away from the rim enough to let some of the air out (not all of it thankfully but scary enough!) they were binned very soon after that.
They "looked" fine, I'm just gald that didn't happen while I was doing any speed.
Even with the small amount it gets used the wegde gets through a set every couple of years (soft Toyo's) and my "everyday" Jag gets a new set every 4 years or so. (Having just changed it I must double check the age of the tyres on the replacement car)

£400 to change a full set of tyres every 6 years is about £70 a year. I don't consider that expensive if it potentially saves my life (or anyone in the car with me). To take this further I change the Griff tyres at 3mm as below that the braking distance increases rapidly as you approach 1.6mm - I'd rather pay for new tyres than risk not being able to stop because I'd tried to delay spending a few quid.
You see a lot of Tivs wearing 10+ years old tyres and you can see then cracks in the tread (and sometimes on the wall) but people think they are safe in a 200-300 bhp sport car. If I see one I tell them as I'd want someone to tell me if the tables were reversed.
