The British Formula 3 International Series will gain a new title sponsor and tyre supply for the next three years, event organisers SRO have confirmed.

Avon Tyres have supplied tyres to the series since 1982 but production will be transferred over to their parent company, Cooper Tire, who will also provide title sponsorship for the 2009, 2010 and 2011 seasons.

Avon Tyres will still be in evidence over the British Formula 3 race weekend though after extending their supply of tyres to the supporting British GT Championship

"We have enjoyed the first three years of working with the British GT Championship," said Cooper Europe managing director, Julian Baldwin. "The mix of cars and their very different handling characteristics really tests our expertise, but so far our crew has risen to the challenge, and they will relish another three seasons of doing so with a field of such high-powered machinery. Cooper's racing tyres deserve to be allied with a high-profile championship in Europe and you don't get much bigger than British F3."

In addition, motorsport insurance specialist Aon will join Cooper Tire in becoming an associate sponsor of the series from next season.

"Aon have reached this agreement with SRO to extend our brand and to offer a dedicated and specialist insurance service to its teams next season," said Sam Pitman, Aon Private Clients.

"This is a fantastic opportunity for all to take advantage of the services offered by Aon, one of the world's largest insurance brokers. Aon have a dedicated motor sport team that has many years of experience in this specialist area and we look forward to working with the British F3 and British GT paddock to provide the cover and service they require"

A substantial boost for a series that was expected to fall under the wing of the British Touring Car Championship until a last-minute deal with SRO was reached, Stephane Ratel was delighted to be revealing two important deals.

"SRO is delighted to announce these partnerships. It is great news that both the British F3 International Series and British GT Championship align with one of the worlds leading motor sport Insurance providers. AON has a breadth of motor sport experience which our competitors can benefit from.

"We all recognise that we are in a testing environment at the moment for sponsorship, but we feel that these agreements constitute a fantastic endorsement of our two British Championships which are both going from strength to strength."
