The Grand Prix Circus has barely had a chance to catch its breath after Motegi before the next round starts in Australia. With a few exceptions, perhaps, a number of teams being forced to either take a much longer route to Australia to avoid the landfall of typhoon Vongfong, or else severely delayed until the worst passed.

Still, to call spending even more hours on a plane or at an airport for what is already a very long flight can hardly be regarded as a spot of rest and relaxation.

Still, they have now all gathered at what is almost unanimously regarded as the best racetrack on the planet. Phillip Island is everything a motorsports circuit is suppose to be: fast, flowing, and deeply challenging. There are plenty of spots for a rider to attempt a pass, or try to make up time, but every single one of them requires either exceptional bravery, or the willingness to take a risk.

The many brutally fast corners which litter the track separate the men from the boys: Doohan Corner at turn 1, where you arrive at a staggering 340 km/h, turn 3, now dubbed Stoner corner for the way the retired Australian champion would slide both ends through it at over 250 km/h, the approach to Lukey Heights, which drops away to MG, or the final two turns culminating in Swan Corner, speed building throughout before being launched onto the Gardner Straight, and off towards Doohan again. At Phillip Island, there is no place to hide.

The tire allocation for MotoGP is set to be expanded when the new tire supplier takes over from 2016. The numbers of tires supplied to each rider will be increased by one or two tires per rider, and each rider will have the option of three different compounds front and rear.

But perhaps the most welcome change will be the return of intermediate tires to MotoGP, for use in practice conditions which are too dry for rain tires, but too damp and dangerous for slick tires to be used.

Bridgestone have announced that they will not continue as MotoGP tire supplier after the 2015 season. The Japanese tire maker will continue for the remainder of this season and throughout 2015 before pulling out of MotoGP.

The move had been expected. Spanish magazine Motociclismo reported two weeks ago that Bridgestone was on the brink of withdrawing, which we covered at the time.

There had been growing dissatisfaction between the two parties over the past couple of years, with Bridgestone not feeling they were getting the exposure they needed for the 20 million euros they spend on the series, while Dorna felt that the tires were not contributing to the spectacle of racing, and were built so conservatively in terms of tire durability that they were occasionally unsafe.

At Austin, the first murmurings of the growing rift became audible. Paddock rumor held that Bridgestone, whose contract was due to expire at the end of 2014, had agreed a single year’s extension to the end of 2015 to allow other tire suppliers time to develop their tires for MotoGP.

With new technical regulations due to take effect from 2016 – all teams will use the spec ECU hardware and software from that point on – starting a new contract period from 2016 makes sense.

Who will take over as single tire supplier is as yet unknown, but that it will be a single supplier is certain. IRTA, representing the teams, is a big supporter of the single tire supplier, because of the cost savings for the private teams.

Big changes look to be coming to MotoGP’s spec-tire system. Now in the sixth season of having a single official supplier, MotoGP is moving closer to seeing the number and variety of tires drastically expanded. With the contract with Bridgestone due to expire at the end of 2014, there is even a serious chance that a new manufacturer could take over from the Japanese tire firm.

A report in the latest issue of the Spanish magazine Motociclismo (available via the Zinio platform), the magazine is reporting that Dorna is looking to change the way that the single tire supply works. Dorna representative Javier Alonso told Motociclismo that negotiations had been opened with several suppliers, including Michelin, Pirelli and Dunlop, as well as current supplier Bridgestone.

Dorna had presented Bridgestone with a list of conditions drawn up by the Safety Commission, the liaison body in which the riders discuss safety issues with representatives of Dorna, hosted by safety officer Loris Capirossi.

Though Alonso does not explicitly name the conditions, he does give Motociclismo some context behind their thinking. The idea is to expand the range of tires available at each race, as it has been all too common in recent history for riders to turn up at a particular track only to find that just one of the two compounds available will work.

There should have been plenty to talk about after qualifying at Phillip Island. Jorge Lorenzo’s stunning fast lap, Marc Marquez getting on the front row for the 11th time in his rookie season, Valentino Rossi’s return to the front row, and his excellent race pace, Scott Redding’s fractured wrist ending his title hopes, so much to talk about, and more.

But one subject dominates MotoGP right now: tires, the incompetence of the tire suppliers, and the stopgap solutions put in place to deal with it.

The lack of tire testing prior to the Phillip Island round has caught both control tire companies out. As such, Race Direction has decided to shorten the Moto2 race from 25 to just 13 laps, while the MotoGP race will now include a compulsory pit stop to swap bikes, and the race length has been cut by one lap from 27 to 26 laps.

In addition, the MotoGP riders are prohibited from using the softer option rear tire, and will be forced to use the harder option. Both decisions were taken on safety grounds, after it was found that neither the Moto2-spec Dunlop nor the MotoGP-spec Bridgestone can handle race distance on the newly-resurfaced tarmac.

The lighter, less powerful Moto3 bike are not affected, and the Moto3 race will run the scheduled length.

If anyone was in doubt that Jorge Lorenzo was a man on a mission at Phillip Island, his first few laps of the newly resurfaced circuit should have served to remove any doubt. Lorenzo bolted out of pit lane as soon as the lights turned green, and was soon setting a scorching pace.

By the time he had finished his first run of laps, he had already broken the existing race lap record, and had got into the 1’29s. He finished the morning creeping up on the 1’28s, before going on to start lapping in the 1’28s and dominate the afternoon session as well.

Lorenzo came to Australia to win, let there be no doubt about that. He knows it is his only chance, and even then, he knows that even that will not be enough, and he will need help from Marc Marquez. “The objective is to win the race, and if I win, that will delay Marc’s chance to take the title, but it will depend on his result,” Lorenzo told the Spanish media.

You could have earned yourself a tidy sum today if you’d correctly predicted the MotoGP front row. Though Cal Crutchlow, Alvaro Bautista and Marc Marquez are all familiar faces on the front row, the combination of the three was quite unexpected. Crutchlow earned his second ever MotoGP pole at Brno, shattering the pole record on his way to doing it.

Bautista was on the front row at Laguna Seca, but his previous front row appearance was pole position at Silverstone over a year ago. And Marquez is a regular patron of the front row, but in four of his eight front row starts, he has had pole. The combination of the three was a surprise, and a testament to the way the new qualifying system this year manages to throw up surprises.

Electronics are to take a further step in the world of motorcycle racing this season. In addition to being abundant throughout engine and chassis, Moto2 and Moto3 official tire supplier Dunlop is to introduce them into the tires. In an official press release issued today, Dunlop announced that they will be using RFID chips in the spec-tires used in Moto2 and Moto3, to keep precise track of the tires used in both classes.

For the moment, the technology will be used solely to track tire usage in Moto2 and Moto3. Tiny RFID chips will be built into the official Dunlop tires during the manufacturing process, each programmed with a unique identifying code.

Sensors in pit lane (shown in the photo here on the Dunlop website) will monitor when each tire leaves pit lane, and when they return. Using the database which maps which tires have been allocated to which riders, Dunlop can keep precise track of which tires have been used when, and for how long.

Dunlop, the IRTA, and Dorna inked a deal this weekend that sees the British tire manufacturer as the sole-supplier of tires for the upcoming Moto3 Championship, which will replace the 125GP series in 2012. With the deal good through the 2014 season, Moto3 teams will run Dunlops for the next three seasons, just as the Moto2 Championship has done. Speaking of Moto2, Dunlop saw its contract in that series extended to 2014 as well, and we wouldn’t be surprised if the two items were part of Dunlop’s ability to put together a more competitive bid than other tire manufacturers.

With Bridgestone set to supply tires in the 2012 season for MotoGP, Dunlop still only accounts for two of the three GP series, but we expect that a sole-supplier for Moto3, Moto2, and MotoGP will emerge in the coming years. Single-tire rules were put in place not only to help level the playing field between competitors, but also to help reduce development costs for manufacturers, and logistical costs for tire suppliers. If a single tire company provided all the grid’s tires, that overall cost would likely drop further, something Dorna has been keen on lately. Whether it makes for better racing though, we’ll let you decide in the comments.
