Yokohama will supply Advan racing tyres with 33 per cent sustainable material content as the control tyre for the Japanese Super Formula Championship from the 2023 season. The tyre supplier said work on the tyre for dry conditions is complete, while wet tyre development continues with a view to providing both to the series from next year. Yokohama says the tyres have demonstrated performance equivalent to that of the standard tyres used in Super Formula 2022 races.
