Guess it depends on how cautious you are. If you can't see the cords then it won't be a MoT fail, just an advisory.

Thanks for the reply, I'm not worried about authorities and such, only about safety. Indeed I can't see the cords, luckily so I just wanted to know if it's too bad to keep on driving as is or if I should change the tyre altogether.

Sorry we don't have that feature. We did years ago (2003/4) but it was turned off due to a security flaw and it was never switched back on.

ok, that renders this forum almost ... unusable

Those of us who use the forum don't find it unusable - we don't all need to be nannied and told there's a new message - just check the forum and it'll tell you if there are new contributions on each thread.

I wouldn't worry. The pressure in a car tyre is far lower than in a much thinner and flimsier bicycle tyre. (Mine recommend 80psi) If you really want to check its conformity and continence, pump it up to the maximum allowed (it'll probably say on the sidewall somewhere - usually circa 50psi) and go for a short drive.

With respect, John F, I seem to remember that the tension in the walls of a cylinder or tube is dependent not only on the pressure but also by the internal diameter.

i.e. A small diameter tube will contain pressures which would burst a bigger tube made of the same thickness of material, this why bicycle tyres can be 'flimsier.'
