That's one he'll of an original/genuine part. Should put some tire shine on it to protect it and see how long it lasts, could end up being worth a bit of money down the track depending on the car

A tyre will last around 7 years. There is no expirey date on them, but they do have a used by date. It is around 7 years.

All tyres have stamps on them to tell you how old they are.

Most tyres go hard after 7 years and can be really dangerous.

I think it would be better to find out if there is actually a requirement to change tyres after a certain time rather just dismiss it out of hand.

I had a problem with a tyre on my GTP just prior to selling it. The tyres were the original Dunlop SP9000's and the right front went flat, luckily in the garage.

It looked like the tread had just started to separate near the sidewall and there was no sign of a puncture. The tyre place told me the tyres should be replaced after 5 years. Didn't matter much in my case as the tyres were almost 9 years old and as the SP9000's weren't made any more I put 4 new tyres on her.

I'd be interested to know if there is some legal requirement or if it's just a tyre manufacturers recommendation.

Yes it is a little amazing to still have it ... only used it once to drive from carlton to oakleigh (in Melbourne) about 20 years ago (25KM trip) after one of my 295 T/A's got a flat
still on the origional ROH 12 slot rim with the chrome wheel trim on it
i think it even still has the rubbery pointy bits on it
havent looked at it since then ..... might open the boot tonight to see what sort of condition its in

It's not a hard used by date, but recommended. It's up to you to decide the risk.

It tells you exactly how old, & why they should be replaced/not used, & what happens to them, on the Bridgestone Web page I linked to earlier. http://www.bridgestone.com.au/tyres/.../care/age.aspx

There is no law currently on tyre age.

But tyres do only last 5 years.

Way to many external factors to determine what age a tyre is cactus.

I think the 5 / 7 years mentioned is to be on the 'safe side'. Actually, in the end you are only talking about tyres. If you don't do a lot of km then does that mean you will never bother changing them???

A car that has had an easy life, with lots of short, low speed trips may have decent tread depth, but what happens if that car needs to brake suddenly, or drive in the rain, or venture out on a freeway??

If it is such an issue, they should include this as a rego inspection requirement. Not many can read or understand the date code. Tyres over 7 years should be treated the same as bald / damaged tyres IMO. Break that cost down to a 'per year' figure and it would be about as much as a dinner for 2 at a cafe for most drivers...

Still VERY relevant, and also mention should be made of the massive import amount of 2nd. hand tyres from Japan, and new Chinese made *could* be a issue [or not?]
