Hey everyone,

 

One thing I have wondered for some time and can't find the answer to the is the following: with all the tire management going on you would think teams would want to preserve tire life by only installing the stint 1 tires at the grid and thus using a different set of already used tires (that they don't plan on using anymore) for the lap from the pit to the grid on sunday. Especially considering the possibility of punctures and dirt from previous race categories also on the track and the fact that they sometimes even make multiple recon laps instead of going straight to the grid.

 

So my question is: are teams allowed to run a different set for the lap to the grid and if so do we know if teams do this?

Yes, they are allowed to do this. And yes, most teams are doing this.

They even sometimes use wet/int for these laps.

Thanks, how do you know this?

 

I am following this sport intensely since 1999 and could not figure it out. So could you please tell us how you found this out? Maybe I am missing out on a source of info. Perhaps a constant onboard feed some of the premium channels offer so you can keep on following 1 driver?

I have only seen them use these in testing and on FP1 installation laps in the dry.

 

However, on a sunday I have never seen it and the TV crews don't stick long enough with a car to see if they change the tires on the grid.

It's part of the things you only see when attending the race

They are still just allowed three recon. laps right, before they have to put it on the grid?

You can see the tyres stacked up by the grid spot before the car gets there. Keep your eyes open during the Brundle grid walks.

Isn't it more a case of the time running out to leave the pits (danger of becoming trapped in the pits with the 15 minutes to go signal)?

I always thought those where emergency sets (puncture in lap to the grid, sudden rainfall etc.)

They have a 15min window, never heard of a max number of laps.

The sporting regulations just set that you have to use the Q2 tyres at the start of the race, so you can do whatever you want before that. Same would apply to those who have free choice then.

 

Also, I saw several times last year drivers in the top 10 going with hard tyres or even intermediates on the grid. If you dont bother to do an representative practice start (or simply cant, as in Austria), then this is what the teams are usually doing.

Most drivers are doing three laps. But there is no limit. You have from :30 to :45 overall 15 minutes time to do whatever you want.

OK. It used to be three laps, I'm 90% sure.

While we are at it: do they refuel the cars to the starting fuel load on the grid, or do they pre-overload the cars with fuel to account for the recon laps?

They pre-overload the cars. This has a simple reason. According to 30.1. a) you can just refuell your car in the garage.

And 30.1 b) also says "Fuel may not be added to nor removed from a car after it has left the pit lane to start the first reconnaissance lap permitted under Article 36.1."
 

OK. It used to be three laps, I'm 90% sure.

Just looked it up, it is unlimited right now. Also looked up up until 2007 and it was always the same ;)

Yeah, good but I remember back to the 90's and the drivers tinkering that last bit with their cars, on these three laps.

I've looked back at rules and can't see any limit to the laps they could do, only a time limit. If they were doing setup changes then 3 laps is probably all they had time for.

This is a useful resource if you want to check. http://www.jomenvisst.de/fia/
