if you drive on options at the start that mean you prime is likely not to last the rest till the end of the race and hence you will have to drive on options again, and you basically starting 25secs behind try to make up by option-heavy fuel and option-light fuel

starting with options are only likely if the prime can last 1/2 distance on starting fuel, and i find it unlikely for drivers to push at the start of the race since the brakes are the same size and they will likely to last only abit longer even with larger brake ducts so driving hard on the start of the race will be a very dangerous thing to do.

Do you mean primes will not last 60% of the race distance? We saw drivers this year on a one-stop strategies doing just that. We also saw drivers going almost 50% of the race distance on options... Tire wear was not a huge issue this past season - the main reason we didn't see more one-stop strategies was that you lost a lot of time when you were running high-fuel, especially in the beginning of the race. With no re-fuelling this is taken out of the equation, and only tire wear is left to determine the number of stops. And since tire-wear isn't a huge issue, I believe one-stop strategies to be faster overall than two-stoppers most of the time. Even WITH refuelling, we saw Kobayashi on a one-stop strategy beat Trulli on a two-stopper in Abu Dhabi a couple of weeks ago...

(Also note that, even if you start on options and find you have to make a second stop for tires, you won't have to go back to options. You could also go for a second set of primes.)

In any case the optimum tire strategy will vary from track to track, it will especially depend on which compounds Bridgestone bring to the track. If it's super-softs + softs, I expect two-stoppers (but not at Monaco), but with soft + medium or soft + hard I expect one-stop strategies to be the norm, and I expect winning cars to start the race on options more often than not, simply because track-position is more important than anything else in F1. (Given that the option tire is in fact the faster tire, which strangely is not always true.)

timbo, I know that tire degradation is reduced in the final laps of the race because of rubber build-up, but this also varies a lot from track to track and compound to compound. And it doesn't change the fact that if you drive a longer first stint than your competitors, you WILL definately lose time and, crucially, positions to those drivers who make an earlier stop. These are positions which you will have to gain back on the track before the end of the race if you want to win. At certain tracks where passing is "easy", this is maybe not a very big issue, but on tracks like Monaco or Hungaroring it means your chances to win are virtually zero.

I do expect the field to bunch-up in the latter part of the race, when drivers who made early stops will struggle on old tires, while drivers on fresher rubber will catch up and try to pass. It could get rather exciting! Much unlike this year, when you gained time by pitting late, meaning that the race was usually over after the final round of pit-stops.

Not only because of that - you work your tyres harder with a heavier car.
It may even be that options won't be suited for a heavy car and would overhead on a couple of laps. However I expect both tyres to be harder.

True...

Could be. I agree that in that case the tire choice will be a bit tricky... If you start with primes you can't make an early pit-stop if you want to go for a one-stopper. While if you start on options you run the risk of having to make a VERY early first pit-stop, which could make life very difficult in the end even on primes. But perhaps that will be the way to go anyway: Start on options, drive a short first stint (until they overheat or whatever, perhaps only 10 laps), then go to primes and go into tire-preservation mode. After you've passed half-way of the race, make a decition if you want to make a second stop (for options OR primes) or gamble on staying out until the end.

Me too, and in that case starting on the softer compound won't be such a big risk. (And even if it turns out that the options still can't quite take the strain of heavy-fuel, you can always pit early and go to a two-stop strategy as explained above.)

What you do NOT want to do, is make your one and only pit-stop after the half-way point of the race, which is what you are virtually forced to do if you start on primes.

So to make some sort of conclusion:

- If you wanna make a one-stop race, you don't want to start on primes because then you'd have to wait until after half-way before pitting for options (because options probably won't last more than half the race). Pitting late will cost you track-position, so you'd rather start on options and pit before half-way. If you then find that the options wear out too early, you have the option ;) to switch to a two-stopper.

- If you wanna make a two-stop race, you might as well do away with the options in the first stint, and make a very early first pit-stop. Then you drive a short second stint (on options or primes) followed by a rather long final stint (on primes).

Either way, you want to start on options. :)

Field spread is another consideration and is dependent on the closeness of the 2010 cars. If you late 1 stop from the lead with an early stopping 2nd place 10s behind you and 3rd place 30s behind, you come out in 2nd with faster tyres and only 1 car to overtake. Giving us viewers an exciting Mansell like late charge to the line as he did so often apart from his championship dominating season.

I think there are too many variables to make a good prediction until after the first 3 races.

Do we know if they have to quallify on the same tyres they start the race with?

That will be interesting... :shock:

Who said that and when? t would be a good/interesting rule though... not really the same exact tires but the same tire type(prime or option)

I have no info mate, just thinking aloud...

It would give the qually and first stint a bit of a twist and we would be certain to get more slightly random grids if this were he case.

I am not a fan of gimmicks as a rule..but this would be a good call.
