In the latest LL, Pete Smith expresses concern that his tyres did not have a MST marking on them.
If you follow the link to the official testers manual, http://www.motuk.co.uk/mcmanual_410.htm, it may help us decide! This is a fantastic document and should help ease everyone through that truamatic time even if is doesnt quite sort out the tyre situation...
The paragraph 'b. Motocross or similar tyres, i.e. tyres where the space between tread blocks is substantially greater than the size of the blocks themselves; which do not have MST (multi service tyre) with an 'E' in a circle or an e in a rectangle moulded into or on to the tyre wall' is the one in question
Trials tyres have always been deemed to be road legal and never questioned because the gap between the blocks is by the sporting regulation less than the block width but I believe that the MST and E marking is a comparatively new thing, presumably generated by EU requirements.
I would doubt that older tyres like Pirelli MT13 and Dunlop Trials Champion (remember them?) have such markings and I need to go into the garage to check what is on my 'fleet' of IRC's. I'm sure Ive seen 'not for highway use' on them as mentioned in the next paragraph.
Hopefully, common sense will prevail and the experienced testers will know the reality of the situation as long as we dont provoke thing by presenting the machine with 4 psi in the back tyre.
