Insurance Void on Old Tyres?

[Guest001]

Its a serious issue. I've been in a car which suffered 2 tyre blow outs in one trip. First tyre was only 5 yrs old about half tread. Second tyre (spare) was 9yrs old and un-used.

It isn't worth the risk.

It is a shame that only the enthusiasts know about this. Not even the law makers have any guidelines or standards set for this. Loud exhausts and speeding are far more important issues which need to be addressed.

Also can depend on the make. A lot of vans had Dunlop LT tyres on them and had a disproportionate number of failures.
I had two on my van and one threw the tread off and wasnt very old but had been a spare for a couple of years.
The other one became deformed and went round instead of flat across the tread. Looked more like a tube than a tyre.
Was about 6 years old and hadnt been used either.
Replaced with Bridgestones and had no more trouble...
If you want to keep tyres for a while they should be stored in the dark and covered up. Also if on a van and stored outside put some cover over them as they deteriorate in sunlight if just left sitting.

they actually begin to deteriorate the moment they are produced. Contact with air is what does it. You don't need just sun.

Is why tyres are coated with a slimy film when they're new, it protects them to a degree.

A reasonable explanation here.

I have also heard of tyres on a vehicle stored in a shed deteriorated faster on the side nearest an electric motor I cant find the site that I saw it on but was an interesting theory

I only know that when I see the perished tyres on one side of the car, it's the side under the carport that faces the Sun most of the day and it's usually the older person who doesn't drive very often. Saw it so many times.

some electric motors (specifically when they use brushes) produce a gas called Ozone and this can be very destructive to rubber products.
