However I can't find any information on tyres?
Is it the same as Class C? i.e. only TKC80 or Michelin T63 are allowed
Although I do find it strange the T63 is still included as it was deleted from the Michelin range in 2016!
All bike classes, A to E, are allowed to use any of the tyres mentioned in the SSR 2020. The permitted tyres is always a work in progress and the rules are updated as practicality allows. On occasions, a tyre has been submitted and approved just before an event and before there’s been a chance to update the SSR.
As the SSR state ‘The MCC wish the competitor to join in the spirit of the event by choosing tyres that are nonaggressive in appearance or destructive in use’. Therefore, a competitor can submit any other tyre they feel meets the spirit of the SSR to the Motor Cycle Tyre Officer
motorcycletyres@themotorcyclingclub.org.uk for that tyre to be assessed and possibly become an approved tyre. The difficulty for the Club arises when determining dimensions of the tread spacing because they don’t always have access to the submitted tyre. So if you’re going to submit a tyre that looks as if it might be on the cusp of acceptable, it’s worth getting hold of a manufacturer’s data sheet, or submitting a photograph with a ruler alongside the tread blocks.
The T63 tyre is still in the SSR because there is always the possibility that there is still some stock with dealers, or competitors have some stored in their garage for future use. I believe tyres can be stored in a good environment for 5 years. These discontinued tyres will eventually reach their best-by-date, whereupon they will disappear from the scene.
The position of Motor Cycle Tyre Officer is a volunteer position and the task of assessing tyres takes time. There just may not be the time to devote to keeping up to speed with what tyres are currently available. So if anyone fancies taking on the position when the current officer moves on, please put your name forward.
