I have found an old one in a dark corner; it's well used but has ample tread left..
these period Michelins hold up well for their age quite supple and no cracks.
no arrow mark
Ideal for a show bike or one that is mostly trailered , but I have happily used this one,its far from new.
Please, This is not to develop a thread on the ins and outs of using old tyres ad nauseum blah blah..
email if interested its a tenner plus post or collect mid wilts.
