Does anyone know what sort of age that old tyres need to be changed due to possible failure/delamination?

I'm guessing at about 10-15 years max but that's really not much more than a guess.

Don't know about "tyres" ,but a lot depende on "tire" useage and storage,inside or outside and temp.These Goodyear's are 18yrs old and still like new with no dry rot .

Yep, storage is the key to longevity. I had a catastrophic tire failure on a chasis dynomomenter at the top of high gear. It destroy my rear quarter panel, took out the overhead lights, and a piece cut my nose. The tire exhibited a bit of dry rot in the sidewall. Lesson learned......

Like most of your petrolhead info.

Funny how you're the only one here who disagrees with the generally accepted definitions of the terms modern classic, classic and antique cars as derived from umpteen sites on the internet that I posted.

Which means that everyone here and God alone knows how many sites on the internet are wrong and you alone are right.

I wonder if you have many of these 'eureka moments'?

I also have to say how much you remind me of the words of Aleksandr Solzhenitsyn when he wrote:

"One can build the Empire State Building, discipline the Prussian army, make a state hierarchy mightier than God, and yet fail to overcome the unaccountable superiority of certain human beings".

Or then again, it could be that the sentiments that have been expressed before might be applicable.

Why are you being combative? So we disagree what defines a classic. So what. To each his own. If you don't like a thread, move on, but don't take every opportunity to take a jab at those who disagree with you.

I think we will enjoy this forum more without the tension.

Mate, that's the problem with you (ex) colonials. You can't spell for shit.

Tyre = the rubber thing that goes between the wheel and the road.

Tire = when you get fed up with something as in tire of Dave's bleating.

Nice sports car, modern classic, classic, antique, modified, muscle or other car BTW.

Just depends on if you are in the wrong part of the world.

Tyre (wheel), the outer part of a wheel in British English (equivalent to tire in American English).

Dang, Heavy Barrel, is the 'Bird yours??!!

Most tire manufacturers recommend 5 years as service life. I sure would follow this if I was running a speed rated tire in a high performance situation. Same applies to a high load tire for trucks or trailers. It is not worth the risk vs. the money.

Tires or tyres are date coded (I used to know the code but CRS) and I like to buy tires that are less than two years old, as they may look good but the materials break down with age. I think I remember that tires made this year the last number in the code is an "0". Buying tires from a discount tire dealer is a bad idea because they handle older manufactured tires that won't be handled by the regular dealers.

This is what happens with old tires. There was 3/8" tread.

ouch

Yeah, that hurts, doesn't it?!

Did you notice that the tire is full of air after the tread seperated.
$8,000 fix.
My son and I were restoring it. We had just rebuilt the motor and front end suspension. Rebuilt motor to honest 350 horse. My 67 will get new tires before I go much further. By the way Goodyear is fixing 74 on their tab.

Unless it is for use in a static display or just, literally, driving it in and out of a garage where it is store, I say no!

Five years is about the maximum for a tyre that is being used or exposed to sunlight as the thing "dries out".

I used to always wonder why people economise on what is the ONLY contact between themselves and the road.

Yep, five years max. I worked in a custom Corvette shop for a while - when between jobs - and we run into that problem and I had to check with a tire maker.

Besides the tire price is marginal compare to the possible damage.
