This maybe a silly question but nevertheless here goes. What is the life of a tyre, I have had my Rover for just over 2years now and all 5 tyres are in good shape with plenty of tread and no visible damage to the side walls, like most classic car owners I only use the car for the spring and summer months doing less than 3000 miles per year.l don't know how old they are as I have no documented evidence amongst the paperwork I received from the previous owner to say when they were put on the car. They could be quite old so is it fair to assume they are still safe to use or is it better to change them for new ones. I ask because my wife's car had a full set of tyres recently on her Honda after 6 years due to small cracks on the side walls. I'm I worrying unnecessarily or do I pose a valid question?
I'd say anything that bothers you can't be a daft question!
This is an often discussed topic because there are so many factors that can affect tyre life. I had a new tyre fail the mot 2 months and 2k miles later with serious cracks on the inside wall and I took it back to the supplier who sent it for analysis by Dunlop who refunded me 75% of the price.
You should be able to find a 4 digit date code on your tyres indicating the production week and year of manufacture. If it's only 3 digits it's pre 2000 and probably needs replacing!
There is lots of info on the web about recommended lifespan, I personally use a common sense approach around condition but with the car mostly sitting I reckon 6 to 10 years tops! My car has sat for best part of 20 years and tyres seem fine but will be replaced before I drive it shortly!
