My car tyres are about five years old and are in good nick as far as I can see, having covered less than 5K miles. If they pass the next MOT that'll do.

I don't see ageing as having much effect on the steel plies of a tyre, so they should be structurally sound. The weather may well affect the rubber over time, particularly sunlight, which is prob why I sometimes see caravans parked up with covers over their tyres. I would expect some visual clues, ie cracking of the rubber to appear before the tyres became a write off.

there is a 'born' date on tyres by way. its a 4 number code giving week and year
mine have just a bit over 2k in a year lol... its a very heavy car tho and i expect wear will be much more on an ev.
edit.. just checked and its coming in at 1.65 imp ton, which for a fairly smallish car is a lot i guess. its 200 kg heavier than my last car the toyota
got it booked in for service for tomorrow.. its well overdue and keeps informing me of fact lol..
I repeat, whatever you think, you need to follow the manufacturers instructions for the tyre. If they state it need to be replaced after ‘N’ years or they have a date stamp on them and year indicator then that needs to followed. Michelin state 25k as wear indicator and they know on most cars they will do 10k a year, so will be replace well before a normal 5-6 years on a car.
I have had this discussions many times when I used to own a Morgan, many old boys would do less than 2k miles a year and keep the same tyres year after year. One had the same set for over 12 years and very nearly wrote his off in average conditions because they were like bullets, this was even after a main dealer at service had told the owner several times to replace the tyres, utter madness.
Another owner had a minor accident, it went in for repair and the insurance company refused to pay out as the tyres were 2 years beyond the recommended date stamp, even though they had 5mm of tread. It cost him nearly £3k for the repair.
So it’s up to you but I would checked carefully
To the driver who said that steel radials are fine. After being on a car for many years sat in a garage, again likely to be wrong. They will flat spot if the car is not moved and used regularly. If it going to sit for long periods, 2-3 months or more, then either over inflate the tyres by at least 10psi or jack it up or put on blocks/axle stands. If you don’t the tyres will deform and driving will be an unpleasant experience due to vibration that you may think is out of balance wheels.
