米芝連拿走輪胎冠軍下台求去...........今年形成BRIDGESTONE上演獨腳戲碼.......

Bridgestone為因應FIA新規則..於2007年度可能在所謂的選配性輪胎"option"tire上加上白線.......

在Champ car系列比賽也有遵照同樣的規則行事.......乃在制造之時在輪胎的側面著以紅邊胎('reds'....請不要說成"紅色輪胎"......因為它們不是紅色的輪胎....法拉利曾經出現過全紅色胎倒是有的....).......在F1的話.......依實際賽車跑道.....若採用選配性輪胎...在拍案決定之前..加上著色記號只是權宜之計.......

制造之輪胎之compound配方有四種......但是一場比賽將只供應兩種........某些賽車場是使用選配輪胎(軟胎)........在其他的賽車場也可能會使用control tire(硬胎)............

Bridgestone的發言人說......新的改制下.......為了順應sports regulation第25.1 B條之第4項細則.......所以才要使用其認可的白色的記號..........

"(Each tyre specification) must be of one homogenous compound and visibly distinguishable from one another when a car is on the track."

其規則上大概是說.....(各輪胎之規格)要用同樣性質的配方........而且一定在跑道上要可以明顯地辨認......

For 2007 onwards, Formula One racing features just one tyre supplier, with all teams using identical Bridgestone rubber. The aims of this move are to create closer racing and to reduce testing and development costs.

At each Grand Prix every team will be given access to two specifications of dry-weather tyre and each driver must make use of both specifications during the race (wet races excepted). A white groove on the tread of the softer of the two available compounds will allow spectators to distinguish which tyre a driver is using.

Over the race weekend, each driver has access to 14 sets of dry-weather tyres. Four of those sets (two sets of each specification) may be used on Friday, with the remaining 10 sets (five of each specification) available from Saturday morning onwards. Prior to qualifying each driver must surrender one set of each specification.

The dry-weather tyres have four grooves and the spacing and depth of these grooves must conform to strict specifications. Although there are currently no regulations on tyre wear during a race, the FIA reserve the right to introduce appropriate procedures if they feel teams are obtaining a performance gain from using very worn tyres.

Teams are free to use wet-weather tyres as they see fit during qualifying and the race. However, during the preceding practice sessions wet-weather tyres may only be used if the track has been declared wet by the race director. Bridgestone may bring different types of wet-weather tyre to cope with various conditions, but all must be pre-approved by the FIA.

All tyres are given a bar code at the start of the weekend so that the FIA can closely monitor their use and ensure that no team is breaking regulations.
