I have directional Michelins as fitted by DC. Looks like I better not swap them over :!:

Does anyone know what the effect of running directional tyres the wrong way :?: I assume it means that any water can't be dispersed. Wonder if it improves grip in dry conditions...

Have just realised that if I buy a wheel and tyre to act as a spare, I had better not get a directional tyre (as I can't guarantee which side will the puncture. Will do some analysis of the tyres available in the UK and post the details.
