WRC 2013 tyre regulations explained

Manufacturers and WRC Teams must nominate one tyre supplier for the 2013 season. P1 privateer drivers, P2 and P3 drivers of 4WD cars must use tyres supplied by the nominated tyre companies. Drivers or entrants are allowed to change tyre suppliers a maximum of two times during the year. All entrants of 4WD cars, except 4WD two-litre turbocharged GpN cars driven by non-priority drivers, must use nominated tyres.

Non priority drivers of 4WD two-litre turbocharged GpN cars, non priority drivers of 2WD cars and P3 drivers of 2WD cars may use tyres from any tyre company as long as they comply with Appendix V.

However, from 1st May 2013, all drivers of 4WD cars using 18 inch rims on asphalt rallies must use the 'world rally' type asphalt tyre which has more grooves than a traditional moulded slick tyre. From 1st October 2013 all drivers of 2WD must additionally use these tyres for asphalt rallies.

Tyre Changes

A maximum of seven tyre changes is permitted on any one rally. To calculate the total number of tyres allowed per rally, organsiers consider a maximum of four new tyres per change, except for P1 and P2 drivers on the Acropolis Rally who are allowed five tyres per change. Tyres may be reused on the same event as long as they comply with any rules around minimum tread depth.

The exact quantity of new tyres for use at each event will be detailed in its supplementary regulations.

Support Championships

Competitors contesting the support championship WRC2, which includes the Group N Cup, must use tyres from the two nominated tyre manufacturers.

Competitors in the WRC3 series for 2WD cars must adhere to the general tyre regulations regarding 2WD cars.
