Look in the MSA News May 2013 (available on the MSA web site if you are a registered competitor), on page 8 there is a heading for 'List 1B tyres' that states that only the 'E-marked' versions are in list 1B.
glad i spotted that on mine too, or it gets pretty expensive. quality jump start the other day Perry, was mighty impressed! i've heard of creeping forward but bloody hell.
