ahem tyres...

[weasel]

i've had three flat tyres on different wheels on cold nights in the past few weeks. i have pzeros with which i am very happy, but for some reason they or the valves don't hold their pressures. i've changed the valve and a leak couldn't be found. so ruling out all the obvious answers, i ask does anyone else suffer this or is some oik letting different tyres down on my car when the temperature gets around freezing?

If all the obvious things have been checked it may be the alloys themselves have become porous and air is escaping through the metal itself! It can be repaired if that is the case iirc

Yeah we had this done on one of the T5's - shotblast each wheel and repainted til the shone like new, cost £45 per wheel IIRC!
