Spanish Grand Prix 2013, Barcelona - Race 5/19

Read this in the Tech regs Article 12.6.3 : Tyre specifications will be determined by the FIA no later than 1 September of the previous season. Once determined in this way, the specification of the tyres will not be changed during the Championship season without the agreement of all competing teams." via @Dom_Harlow

Not really a problem - I don't think any team likes the current tyres lol

The teams are unable to agree on anything.

But its a moot point, as the FIA write the regulations so if they wanted to force through a change they would just issue an update to the technical regulations stating that article 12.6.3 no longer applies.

Why not Merc as well? They clearly have a fast car, just have issues with tyre deg

I think RBR and Merc both stand to benefit the most, Ferrari might get some pain and Lotus probably the most pain.

Would be very hollow and farcical if Merc and RBR gain from a mid season tyre change.
 
Would those light on tyres not also benefit?

Say Lotus can do 3 stops while others need to do 4. More durable tyres that allow others to only stop 3 times should also mean Lotus will be able to do only 2 stops?

Any improvements in durability will affect everyone. Any teams who have light tyre wear will continue to have light wear. It won't close the gap up.
 
It's not just that. What if the teams with the lower tyre attrition rate can't get the tyres up into their operating window? Then they'll degrade just as fast as if they're overheating.

See the pre-season tests for evidence of that.
 
True.

I just don't think its going to be the massive advantage for some teams while completely ruining other teams that people are suggesting.

I also don't think fiddling with the tyre compounds is the answer either.
 
What it sounds like is Bernie being Bernie. Make a public comment that's to the extreme of what you want, and it will force peoples hands in that direction. The guy is no fool, he knows what he's doing.
 
I still find it unbelievable that they allowed F1 to be so advanced with aerodynamics that you cant over-take unless u have DRS or else you are stuck behind the car even if you are faster.

F1 needs an overhaul in the regulations, the tires are to extreme and dictating races to much.

Formula 1 tyre change: tech implications of Pirelli's decision

Pirelli's decision to change its tyres from the Canadian Grand Prix onwards will potentially have a far-reaching effect.

Tyres are an integral part of the car's design, affecting the aerodynamics and the suspension.

With changes to the construction moving back towards the 2012 tyre specification, married to the current compounds, teams will be heading back to their computer screens to re-optimise their cars around the modified tyres.

AERODYNAMICS

Tyres have a big impact on the airflow around the car, not only because of their size but also because of the sidewall profile and the way it deforms.

Traditionally, the impact has been more critical around the front tyres, as with the front wing in close proximity to the tyre, small changes in this area have a compound effect downstream.

But with the increased importance of air and exhaust flow around the rear tyres in the current generation of grand prix cars, there will also be implications for the rear end.
For windtunnel testing, Pirelli supplies 60 per cent scale tyres, which accurately reflect the deformation of the tyre.

Teams should be able to revert to the 2012 windtunnel tyres for aero testing.

Because of the change, teams will need to produce new versions of wings, endplates, floors and brake ducts.

SUSPENSION

The change to the tyre construction will impact the suspension.

Teams are provided with Pacejka models of the physical properties of the tyres by Pirelli, allowing their accurate representation in simulations.
As with the windtunnel tyres, it will be a case of reverting to known 2012 tyre data.

From this base, teams can look at revising their spring, damper and linking rates to account for the difference between the new and old construction.

Additionally, the suspension geometry will need revising to get the camber gains and the roll-centre location that work with the older tyres.

This requires revised suspension elements at the front and rear, necessitating new patterns, moulds and wishbones to be made, which is a significant investment mid-season.
Teams are faced with a large, but not insurmountable, challenge to adapt to the new tyres given the experience gained last year.

But it is a drain on resources for teams already stretched to develop new cars for the 2014 regulations.

The combination of the old tyre construction and new compounds will also be untested by teams going into the Canadian GP, which is quickly followed by some punishing, fast-flowing European tracks with unpredictable weather.

So any steps to stabilise the racing with these tyres could be offset by the effort required to adapt to them.

More cost saving :D

Over 1 lap, Merc have THE fastest car. No doubt about it.
Their problems are that they shred their tyres at an astonishing rate.

RBR are in a better position, because they need a tyre which is only "slightly" more durable that what we currently have. Remember, Vettel is currently leading the championship.

My understanding is that Pirelli shall make the tyres "slightly" more durable, which works nicely for RBR.
Merc on the other hand, need a tyre which is considerably more durable and Pirelli are not going to be giving them this tyre.

Given the above, my belief is that we will see RBR consistently on the podium and Vettel should win the title without too much trouble.

Out of interest, I think Merc did 3 stops in the last race (am I correct?). Given that they were so harsh on tyres, why did they not stop 4 times?

This is exactly what RBR and Horner are hoping for.

I've seldom seen a team principal look so dejected and p'd off as Horner did in Spain, given that his team are leading the WCC and his driver is leading the WDC.

Horner is so damn competitive. I wish other team bosses could take his approach.

BTW, is M. Whitmarsh due to be replaced? In the last race, I hardly saw him interviewed...as though the team asked him to keep a low profile ahead of his removal.
