First of all, the sole tyre supplier, Bridgestone, has announced that it will quit F1 at the end of 2011 when its current contract ends. This came as a shock. With the spotlight on car manufacturers, it doesn’t seem to have entered anyone’s mind that a company such as Bridgestone, which has been so incredibly loyal to the sport, would consider upping sticks.

I can remember a time when Bridgestone were not in F1, but only just. When I started watching Formula 1 in the mid-1990s, Goodyear was the sole tyre supplier. But Bridgestone entered in 1997, beginning the “tyre war”. When Goodyear left soon afterwards, it was not long until Michelin came in to begin an even fiercer tyre war.

I wasn’t a big fan of the tyre war. Mostly, one tyre was a major advantage over the other, so we were essentially left with two championships — a Bridgestone championship and a Michelin championship. Considering Bridgestone practically tailor-made their tyres to suit Ferrari, this essentially made Ferrari a shoo-in for the championship every year. That was until the 2005 regulations — which banned mid-race tyre changes — handed the advantage to Michelin in a big way.

2005 was the year when the tyre war well and truly jumped the shark. In the quest for the competitive edge, both companies had made their tyres softer and softer. The resurfaced banking at Indianapolis bit, Michelins exploded all over the shop and we were left with a farcical race in which only the six Bridgestone-shod cars competed.

On the back of the problems, the FIA decided that a sole company should supply the tyres for all the teams. The problem with this was that it had the potential to severely reduce the amount of exposure that tyre company got. With no tyre war to talk about, people might not talk about tyres. For this reason, Michelin refused to have any further part in F1.

The upshot was that Bridgestone and the FIA colluded to concoct the maddest new rules and gimmicks in order to contrive some interest in the tyres. One has to paint green lines all over the tyre in a crass attempt to pretend they care about the environment. Of course, the green on the tyres clashes with teams’ liveries, making the scheme not only nonsensical, but also damn ugly.

Teams are also forced to use a sub-optimal tyre compound at some point during the race. While this may have superficially “spiced up” the action, it is artificial. Drivers are critical of it, and Fernando Alonso even said that he would rather race with wet tyres on a dry circuit.

Moreover, there is a sense that Bridgestone may have deliberately made their tyres behave strangely in an attempt to get drivers and teams discussing tyres with the media. Nick Heidfeld has said that the tyres could be “ten times better”. Joe Saward expanded:

The Bridgestones react differently on each car and finding the tricks that make them work is not easy. Some drivers can do it at some tracks and not at others. Even World Championship challenger Jenson Button has struggled with this…

Bridgestone seems to have concluded that it is better to have people talking about the tyres rather than not talking about them – even if a lot of the references are negative.

I rejoiced when it was announced that a “control” tyre was to be brought in. But it has brought the wrong sort of control. I am not too sure that the current dark behaviour is an improvement over the honest competition of the tyre war.

If you have reached the stage where your marketing strategy is to have people make negative comments about your product, it probably is time to call it a day.

In many ways, Bridgestone get a huge amount of brand exposure through their involvement in F1. As noted in this week’s Formula1Blog.com podcast, you simply cannot watch a Grand Prix without learning that Bridgestone supply the tyres. Yet, after thirteen seasons (fifteen by the time they leave), the marginal returns to their investment must surely have diminished to almost zero. And As Keith at F1 Fanatic has pointed out, their costs are set to soar as they now have to supply twelve or thirteen teams rather than ten.

Nonetheless, it is a shock and a surprise that Bridgestone, a company that has stuck with F1 through thick and thin since 1997, has so abruptly pulled the plug. Now the FIA and Bernie Ecclestone will have a big headache trying to find someone to take Bridgestone’s place. With bridges burned with Goodyear and Michelin, and Pirelli uninterested, options seem thin on the ground.

Two years on, and I’m beginning to wonder if anything actually changed. Even with a single tyre manufacturer, the performance of the teams seems to fluctuate wildly for seemingly little reason. And what is that reason? Tyres of course.

This seems to be the stock excuse that explains just about everything in F1. If Sébastien Bourdais is not performing, it’s the tyres. If Nick Heidfeld is struggling in qualifying, it’s the tyres. If Kimi Räikkönen is trundling around in 6th place, it’s the tyres.

Now Ferrari have been complaining about the compounds that Bridgestone have chosen in recent races, claiming that Bridgestone have tended to edge towards the harder end of the range. Hard tyres, we now know, suit McLaren well, whereas Ferrari prefer softer tyres.

Ferrari’s technical director, Aldo Costa, complained in particular about the compounds that Bridgestone took to Hockenheim — a race that the McLaren of Lewis Hamilton dominated:

I think the last race for us was very difficult for finding the good grip from the tyres, but we were not the only team. Most of the drivers were having, during the race mainly, a lot of problems to find grip.

The tyres were very, very hard, probably too hard for that kind of circuit, especially the hard tyre. There was no wear at all; the tyre just was not working for that kind of circuit. This was valid for us and it was valid as well for most of the teams.

It is a bit rich for Ferrari to be complaining about Bridgestone. The Japanese tyre company has spent the best part of the past decade pandering to the Scuderia’s every need while every other Bridgestone runner was told to suck it. At least Bridgestone are now treating their role as sole tyre supplier to F1 without favouring their old partners any more.

Bridgestone’s Hirohide Hamashima has backed up the theory:

“Basically the Ferrari has more of a tendency to understeer than the McLaren,” Hamashima told autosport.com. “The McLaren is a little bit oversteery. When the tyre has good grip, the car with the oversteer tendency will be quicker over a single lap than a neutral or understeering car.

“But when you think about racing conditions – especially with the temperatures we had at the Hungaroring – then an oversteering car will have heat generating at the rear much higher than the understeering car.

“Looking at Hungary and (Lewis) Hamilton’s car behaviour, after a few laps he struggled with oversteer – so he was making lots of counter-steering movements. On the other hand the Ferrari had a good balance after a few laps.

“That’s why the temperature is making a difference.”

I have learned this year that even with just one tyre manufacturer in F1, tyres still make a huge difference to a team’s performance. You could argue that, when everyone is given the same tyres to use, it is up to the teams to find a way to maximise the performance of the tyres themselves. However, with four compounds for Bridgestone to choose from, the teams simply have to build their cars not knowing which tyres they will end up using most often.

Perhaps F1 could bring in a genuine control tyre, where Bridgestone make just one compound of tyre for all circuits so that the teams will know exactly what to expect all season. However, Bridgestone would be dead against this because they want people to talk about the tyres more often. Also the performance of the tyres would probably vary from team to team depending on the weather conditions and the characteristics of each circuit.

I suppose I should just accept that tyres will always play a huge role in motor racing. With tyres being the only part of the car that really propels the vehicle, their importance ought not to be such a surprise. But I’d even rather be talking about how important silly aerodynamic pieces like shark fins are than talk about these dull, dull, dull tyres.
