F1 teams to test slicks at Jerez!!!

The problem with two or more tire manufacturers is that the battle on track goes from team/driver to a tire war. And then it is an even more unfair fight. Wouldn´t you agree? It´s a really old story, if one team wins, it as most likely because of the tire advantage that they had, and vice versa. It takes away from the actual advantage a team might have, whether its in car design or its driver´s ability.

I still say this is more interesting than spec car

Whoever was giving your lecture about vehicle dynamics at your university was clueless about tires.

Regarding tire wars.. it would certainly be very cool for the sport. I'd love to see it.. Goodyear especially, being an American company and the dominant force in F1 so long. Even Michelin getting back in, or Pirelli, or anyone.. would make things interesting.

But all those companies are just that, businesses. Competing in a race series is expensive as is.. much less F1. Plus if the company isn't Europe-based, think of the expense to ship 4000+ tires every other weekend, plus a staff of engineers and techs..

Who was that directed to?

I believe that this is what Bridgestone does? They are based in Japan IIRC. Although they have factories throughout Europe, but I don´t know if this is where they manufacture the F1 tires. Does anyone recall any information over that?

Was directed to Chubbs saying contact patch area has no effect.

Even if it were a perfect lab environment, its a big deal.

F.Massa from GPUpdate.net:

Some might expect it will cause more overtaking moves but I can't agree with them. It is more dangerous as we lose some grip, especially with slicks.

Why have drivers stated that they loose grip, especially when on slicks

As I understood, slicks represented an increase in mechanical grip in comparison to grooved treads. Although the variation in compounds does exist as well, but for the most part, shouldn´t slick tires provide more grip than grooved tires

I believe Massa was comparing slicks vs grooved w/out TC and on the new ´08 ECU.

Its conceivable for this testing, though I'd be surprised. This is only the first iteration of a slick for an F1 car in close to 10 years. Lot has changed. Design of a slick is much different than a grooved tire.

Bridgestone will probably have to go back and tweak some design parameters, give it a go another time and keep iterating (especially with aero changes) until they come up with something they and the teams are happy with.

"mechanical grip" is the grip given by the weight repartition on the tires.

Slicks give better overall grip by having less load sensitivity and/or better friction coefficient.

Thus the correct word, i think would be "better tire grip" which refers to the coefficient of adherence.

Having more grip from mass is not desirable for a car as everything that experience inertia will have performance decreased, in other words, if the tire has more weight on him he will grip less(if you we talk about medium-high speed).

Thus the real deal is having a light car, a lot of downforce that is a fictive load (doesn't increase the weight, it transfers a stress) and have a coeficient of adherence high even with a lot of loading.

In this condition Slicks tires offer better Coef of adherence vs Normal Load, thus better overall grip.

To me, this makes the most sense. Thank you!
