The offical blurb states that the Cup and Trophy have tyres with stiffer sidewalls. Is this a feature of the PE2, or just the version fitted to these cars. If the latter, what are the identifying marks?
Also any idea if it is possible to find out on a factual basis what other makes of tyre have similarly stiff sidewalls
