It appears that all F1 teams will be forced to use both a hard and soft compond Bridgestone tyre during each race in 2007 with Red Rubber being used in one compound to allow views to know who is running on which compound at any time during a race.

In a bid to spice up on track action in the new era of a single tyre supplier, all teams will complete each race using a combination of tyre specifications.

The 2007 FIA Sporting Regulations (article 77) state

a) Each team will be allocated eight sets of dry-weather tyres, four of each specification, for use during P1 and P2 [friday sessions]. These are the only dry-weather tyres which may be used during these sessions and must be returned to the tyre supplier before the start of P3.

b) Each driver will be allocated ten further sets of dry-weather tyres, five of each specification, for use during the remainder of the Event. However, one set of each specification must be returned to the tyre supplier before the start of the qualifying practice session and may not be used during the remainder of the Event.

c) Prior to the start of the qualifying practice session wet and extreme-weather tyres may only be used after the track has been declared wet by the race director, following which extreme, wet or dryweather tyres may be used for the remainder of the session.

d) Unless he has used wet or extreme-weather tyres during the race, each driver must use at least one set of each specification of dry-weather tyres during the race.

It is thought that borrowing an idea from Champ Car racing, the softer compound will be identified by having a red tyre wall.
