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.
