F1's tyre supplier for the upcoming year is back to work as it carries out another test session in a Toyota TF109 at France's Paul Ricard Circuit. Nick Heidfeld had the opportunity to run the test circuits high speed configuration, and was greeted by nice 28 degree weather.
All followed by the traditionanallly super-soft Pirellis, see how the do on marbles?Jersey Tom wrote:You're making the assumption that hard compounds don't make marbles.
Perhaps you can explain how to achieve good grip without marbles and lots of rubber on the racing line.Jersey Tom wrote:You're making the assumption that hard compounds don't make marbles.
Easy - hard tyres = (dust not marbles) + ground effects - that should solve the problem quite easilyWhiteBlue wrote:Perhaps you can explain how to achieve good grip without marbles and lots of rubber on the racing line.Jersey Tom wrote:You're making the assumption that hard compounds don't make marbles.
True.Jersey Tom wrote:You're making the assumption that hard compounds don't make marbles.
Because passenger cars drive in a straight line, not cornering at 0.5+ G and shearing the rubber off the treads.lebesset wrote:not an assumption that hard tyres don't leave marbles , just drive down the road and look ! much more traffic yet no marbles
Is that more like tire designers want the marbles, but maybe drivers and fans don't?Jersey Tom wrote:Beyond that, believe it or not, you WANT the marbles.
Only in the US. In the rest of the world we have cars that go around cornersJersey Tom wrote: Because passenger cars drive in a straight line
All (non-US) road cars will corner at 0.5+g. Or did you mean 5.0g?not cornering at 0.5+ G and shearing the rubber off the treads.
Not if they result in a track that is so lacking in grip off line that an overtaking driver is unduly penalised by having to go off-line to make the pass.Beyond that, believe it or not, you WANT the marbles.

It seems to be difficult even for an expert to answer the question. How often are we told that nothing ever is comparable between different series like NASCAR and F1 in terms of tyres. Is a simple question how tyres can have grip without smearing the racing line with rubber and the off line area with marbles so difficult?Jersey Tom wrote:Because passenger cars drive in a straight line, not cornering at 0.5+ G and shearing the rubber off the treads.lebesset wrote:not an assumption that hard tyres don't leave marbles , just drive down the road and look ! much more traffic yet no marbles
NASCAR tires in comparison to F1 are pretty f'in hard, and they leave marbles. Beyond that, believe it or not, you WANT the marbles.
I think the FIA has stated they want a single supplier in order to prevent a tyre war...ISLAMATRON wrote:Has it been decided that it is either or?
Yes, but isnt 1 of Michelin's conditions tire competition? Or are they willing to drop that for the big pay day?Just_a_fan wrote:I think the FIA has stated they want a single supplier in order to prevent a tyre war...ISLAMATRON wrote:Has it been decided that it is either or?
Depends how big the pay day is I suppose.ISLAMATRON wrote:Yes, but isnt 1 of Michelin's conditions tire competition?
