thanks.

best to ask Jase aka LUDO2C our resident F1 guru

what do you mean by change tread anyway? as in change the tread pattern of the tyre during the race? (well, according to this years one set of tyres rule - no?)

or change the tread during the season? or change to different treads to suit different circuits/conditions?

have to be a bit more specific i think?

New Rules 2005: You cannot change any tyres for performance gain. Only for safety.

In the beginning of qualifying i believe, the teams choose their tyres. These tyres cannot be changed until after the race. Unless if the tyre is punctured or has flat spots, like Raikonnen had. He couldve changed them if he wanted to. Coz it could of put him at risk. He was pretty lucky to just walk away from that incident.

So yeh thats the rules.

Do you mean altering the tyre during the race? Like putting cuts in the tyre? If that ir what you mean, then I'd say no. F1 tyres don't work that way.

And I'm pretty sure there are only two tread patterns for F1 tyres. Dry tyres and wets. As far as I know there aren't even intermediates. Is that right?

where's Jase?

If you mean change the tread to say 2 strips then NO!
The FIA sit down with both tyre manufactures and explain the rules.

There are Dry, wet and intermediate tyres.
I haven't read/heard anything of no intermediate tyres.

Remember, the F1 teams don't even put the tyre on the rim, they just adjust the tyre pressure on them and thats about it.
Michelin and Bridgestone staff do everything else.

Have I answered your question?

i think the only thing they can change is the compound yea?

[Javed]

They do have intermediates.

i think the only thing they can change is the compound yea?

I think on Friday they tell the tyre company which tyre they want to use for the weekend after Friday practice.

if thats the case then wonder what happens to all the tyres they bring along to a race 'just in case' certain conditions come up

i guess they just go back into the stockpile and get used for testing or (heaven forbid) get destroyed and sent to the great tyre yard in the sky

FIA fix this 1 set rule...

its dangerous not being able to change tires...

imagine teams changing tires in kimi's situation (well his case there was a huge flat spot) and then post race the FIA deeming that the tires were still 'race-able'...
-_-

too much ifs into the equation...
