Tyres "perishing"

You obviously don't. It has been discussed in depth, that the pressure will reduce in cold weather, and increase in hot weather.

It's no good just checking them, but never adjusting them.

I bet that you check your tyre pressure every time that you pedal your car don't you ?
And make allowances for the ambient temperature - not...

I said that I do check my pressures - which I do at least once a month and since they are always correct +/- 2 or 3 psi - I never top them up or let any air out .....

Physics tells me your wrong.

Yet again you have been rude to people who are trying to help you. I have seen you do this several times in this thread alone.


When you consider that at it's coldest the temperature dropped to about -15 degrees C last winter, and reached over 30 degrees C this summer. So with a 40 degree swing in temperature, that would mean over 4psi difference. It would be irresponsible to not correct your tyre pressure for that 4psi change. And it could contribute towards the perishing.

At last - you have told us what correct means to you.

It appears that if they within 3psi of correct that's good enough / near enough.

All other things being equal you run part of the year with them under-inflated and part of the year over-inflated.

So the average over the year is fine is it?

I check the pressures with the tyres 'cold' i.e. before the car has been driven and alter them to suit the season.

Every time you check the pressures a tiny 'phst' of air can be heard - if nothing else that will drop the pressures over a year.

This thread ha now lost all credibility.

I agree - goodbye

I think it lost credibility when the OP asked advice, and then was abusive to anyone who dared to suggest that the problem was anything but the fault of the tyres.

If that had been the case, and they knew that from the start, then why ask for advice??

Some people just can't stand the fact that they may be wrong.

Going back to the original topic for a second. My 2010 Fiat Punto has continental tyres too and I noticed about a year ago that the rubber was showing signs of perishing.

I definately won't be replacing these with Continentals as, with the exception of Wan-li's, i have never had such a poor gripping tyre. It is so easy to spin up the wheels and it is only a 1.4!

My (not quite) 2 year old car - has done less than 12,000 miles and I noticed this afternoon - that between the treads of all 4 tyres - there are small cracks (lengthwise) in the rubber
Could the tyres be perishing already ?
The tyres are Continental 185/55 R16
Is it worth my contacting Continental to ask why ?

tyres being made of rubber have a shelf live also heat and sunlight can accelerate deterioration. Iif you look closer at the sidewall there will be evidence that something was added to the mould this is the date stamp. how to decode it you'll have to google
