Both of the series that you mention do not run a road based control tyre. I understand they have the option to run wets so their tyre performance in colder/wet conditions is not an issue.

I have spoken to the Pirelli representative this morning and they have confirmed that the reason for the recommendation of the use of the HR rated tyre is to do with cold/wet weather running. In cold/wet weather with lower track temperatures an HR rated tyre will run at operating temperature apreciably more quickly than a ZR rated tyre, given the weight and performance of the bikes to which they are fitted - equally they will cope with dry hot conditions without any problems.

The suggestion is that an HR tyre will get to proper operating temperature in a couple of laps max - you can push it from the race start - on a ZR tyre you might need 2-3 racing laps to get them up to temperature on a cold/wet day and that has safety implications, after all you are racing from the moment the lights go out - who would wait for their tyres to get up to temperature?

Can we have a name for this Pirelli representative? As I have been unable to find anyone in Pirelli who will commit to such a comment.

I'd like to know who shot JFK?

Does the whole Z or H rated issue become a bit of a non-issue as MY supplier - Micheldever Tyres - has advised me that their supplier tells them the "Pirelli don't make the H-rated Diablo anymore"?

Maybe we have to consider the use of a different tyre or manufacturer for 2010..............oh, hang on, I appear to have fallen through a wormhole in time....

We've used 5 sets of tyres this season. I reckon class B's could get away with 3-4 sets a year. Anyone want to buy some second hand tyres? because thats what I'll be using this saturday.

I reckon we've spent more money on diesel and petrol for the bike.

We've got our tyres form all matter of sources, my local Honda dealer, Holbeach and Neil at Cornerspeed offered to get me some too but we'd brought them all. Never had a problem and you pays your money and get your tyres, done!

If the Rosso does get through on H then thats an excellent progression, but looking at the race times, these tyres fit the bill well and I have to agree about the Z's probably not good enough for wet or cold days. Model car racing used a set of tyres per race and it got silly....

See you all at the weekend for the last one

Mate, we ran the ZR tyres on both ours from the beginning and you know how they went.
Also who remembers the epic domski and andy j battle in cold torrential rain at brands hatch in early april 2006 when they were banging farings for much of race 1 and never had a tyre issue and both were on the ZRs then.

I'm keen for this post to be a new DD record.

1. I'm not sure the MT are banging on about keeping the costs down? It has been the ongoing principal in DD.

2. Crappy road tyres seem to have worked for a number of people over the years - Cobby, Andy, Matt T., etc,etc,etc,

3. As ever people can choose to spend what they like - within the agreed guidelines/rules, blah... Does my Corse Tshirt make me faster?

4. Rules have been reviewed/changed and agreed every closed season of DD.

5. Volunteer organisers seem to be doing OK, over the last 5 years.

6. People come, people go - thats life, stay if your happy, go if your not.

7. Is it broken?

In summary DD has been/is a great series with a great paddock atmosphere, long may it continue.
