FIA opens 2017-2019 Formula 1 tyre tender process

The FIA has officially opened up the tyre tender process for Formula 1 for three seasons from 2017

Current supplier Pirelli's contract expires at the end of 2016, but the process has already started to discover which organisation will take on the next three-year contract.

Michelin, last involved in the sport in 2006, has suggested it is interested, but only on the basis it can supply longer-lasting rubber and on 18-inch rims [pictured on a Formula Renault 3.5 car, below].

Ecclestone: Michelin ideas bad for F1

There are moves afoot to alter the width of the rear tyres from 2017, from the current 375mm to 420mm, to offer a more aggressive look for the cars and in turn provide better racing.

With regard to the tender process, companies are invited to become the single supplier by submitting a proposal by June 17, with the selection procedure to commence the day after.

SURVEY: Have your say on F1

By July 17 only those candidates whose proposal complies with the technical and safety requirements will be put forward for final consideration.

In documents seen by AUTOSPORT the FIA has made clear to the candidates that "whilst the wheel diameter is currently set at 13 inch, this should not preclude an increase in diameter if the tyre manufacturer feels there may be advantages to the competitors by doing so", with details to be supplied.

While not mentioned in the documents, AUTOSPORT understands there are discussions in place whereby the number of dry compounds could be increased from four to six in the future.
