TYRES

[BREEZER]

I will be racing on fresh grass with some bumps and wooden jumps.What i
woould like to know is I have the following tyres

1=sch mini spike yell for dry grass
2=sch mini spike green wet grass

now where do the new GRP cone spike and the ballistic mini spike pink&green fit into the above. And is it true that the GRPs are a better all round tyre.
THANKS,
MARTIN

In my experience I used GRP's for a whole day and it was nearly 8 complete runs before they lost grip, so although the spike wears down I think the tire still has good grip.

the GRP tyre is good on grass and as said it keeps the grip levels better than yellows as the tyre wears. There might be a new compound out shortly on a par with sch green for wet weather.

BB greens are ok on grass but not as quick as sch yellow in the dry. They do work fairly well in the wet grass though. Pinks you wouldn't really use much unless the track is very bare and dusty.

GRP's should be an alternative to Yellows so good for Dry Grass
BB Green Spikes will be better on wet grass in most cases, i'd usually them on the rear with Sch Green mini's on the front - you should have more traction then with Green mini's all round anyway i'd say.

BB Pinks are good on some Astro tracks, and also good if the grass wears away so the track is almost dirt...

I think the GRP's also work better in the transition between wet and dry, or just after a light shower.

I'm sure we've all been caught out on yellows in the damp, sometimes they are ok (usually if they are new), but are usually like being on ice!

I 100% defo agree on this as this happened to me at Batley last year. You know if you're in a run and as soon as a single drop of rain comes, with yellows the run is over and they become a nightmare. Well the Conespikes don't do that, they are like a green and stay with you in terms of grip and balance.

So they are faster than a green in the dry and miles faster than a yellow in the wet. Faster than a yellow in the dry or a green in the wet? More testing will be needed

With all the feed back on GRP Tyres, I wonder why they got deleted from Stotfolds preferd tyre choice for National.?? As I have been informed that this is the tyre they originally chose.

[modelimages]

there were no sinister reasons, at Stotfold the choice was Schumacher yellows or greens, ballastics gave no advantage in any conditions and originally our intention was to specify a tyre that would work as an alternative, we had some limited testing of the GRP and found that it worked in the dry but was no better or worse than the schumacher, this we felt gave the racer an alternative, however with no wet compound in the GRP range there was no alternative if the track was wet. following discussions with the BRCA committee the options were to specify BB's which at least gave the racer two options for each weather scenario, we were also aware that we would be the only track specifying GRP for a national, we would have continued to spec that tyre if it was clearly better than the alternative, it wasn't so we decided to stick with BB's

[Cockerill]

Ash, I'm talking about Stotfold as the original question was related to the tire selection for Stotfold National.
