The grooved tyres currently in use are scheduled to be scrapped after 2008, but Mosley has told Autosport magazine that if new bodywork rules, intended to reduce aerodynamic downforce by up to 50%, to not sufficiently reduce cornering speeds, the return to slicks may yet again be postponed.
"The theory is, much less downforce and more mechanical grip should improve the racing and overtaking," Mosley said. “If it turns out that the promised reduction in downforce hasn’t happened and the cornering speeds go up, we’ll just put the grooves back in."
