Higher torque from Turbos mean wear rate difficult to quantify.
Yet again Pirelli find themselves unable to get the car data they require. ::)
Teams seem to think they can operate in a vacuum. :crazy:
Pirelli has floated the idea of increasing the width and diameter of the rear tyres for next season in a bid to ensure they can cope with the increased wear.
With Formula 1 introducing new V6 turbo-charged engines next season, the torque demands will be far greater than at present and Pirelli have expressed concern that without enough data, they're in the dark as to what demands the tyres will need to cope with.
In an effort to gain more information, Pirelli requested the teams supply expected performance data to aid their development, however only a handful of teams obliged.
As such, the FIA is believed to have stepped in and demanded the teams supply the requested information before the end of next week, as well as extending Pirelli's finalised structure/compound deadline by a month.
With the performance data the supplier already has, it believes widening the tyre would be the best solution to ensuring it can cope with the demands of a turbo-charged engine and the new ERS-K unit which produces an additional 161bhp for 33.3 seconds per lap.
The idea has been put to the teams, however they are believed to be against it as it would require complete re-designs of their rear-suspension layout to cope with the larger wheels.
A decision is expected to be made toward the end of the summer break in August

The rumor has Ferrari are not in the favor of widening of the rear tyre, while Mercedes was hoping for that advised widened back one. I think this will create some significant debate as the development aero as well as rear suspension are so much dependent on to that..

I don't know why teams wouldn't want Pirelli to have their data.
What's the advantage in having the tires designed to fit your opponents design and not your own?

I understand the teams not wanting to have to redesign the rear suspension etc for the wider rear tire but would they rather watch as their cars eat through the existing rears as the Turbo's put more demand on the tire compound as it stands now.
You think there are tire issues now....just watch if nothing changes but the engines.

The new exhaust rules mean even the Coanda effect will be gone, so there will be less down force as well. Hello wheel spin!
