Everybody can use H rated Diablos which have worked well for DD over the previous 4 seasons. If it hadn't been for Holbeach having problems sourcing Diablos towards the end of last season and it being implied that was due to them being replaced by Rossos in the not to distant future.
It then required both types to be written into the 2009 rules and the original news on Rossos was they would be available later in the season probably around late May, so it was always envisaged that the first couple of rounds would be raced on the standard H rated Diablos.

It now looks as though Pirelli have had a change of mind with regards H rated Rossos and are just doing the ZR rated ones which were not even listed in the 160/60 size on the Pirelli UK websit last July.
As I see it there are two options with regard to Pirelli, they either keep producing the standard Diablo that we have used so far or they sanction the use of the ZR rated Rosso. As this is a liability issue the decision on this probably has to go to someone near the top in the main company.

In 2005 the original rules only specified Diablos and not the rateing so back then we did use ZR rated tyres when the official support for the series was A&R racing, it wasn't until a DD update note in March 2007 that H rated tyres were really mentioned and that was only when the prices were quoted for them when supplied by Holbeach, it wasn't until last year that the rating appeared in the rule book stating H rated tyres were to be used.

Now I don't know how much information Gordon has with regard to our use of Pirelli Diablo tyres over the years as he has only been involved with DD since early last year so may not have realised that they initially sanctioned ZR rated Diablos


One solution would be to say No other tyre than the standard Diablo to be used before the Snetterton meeting which would mean an investment in a set of H rated Diablos now should serve as race tyres for the first two rounds and buy a bit of time for negotiations over the use of ZR rated Rossos or a supply of H rated Diablos to be secured by Pirelli UK
