As part of its association with the World Series by Renault (WSR), Michelin will supply Renault Sport its Pilot Sport S9L for the new Renault Sport R.S. 01. Michelin will provide the tyre in two sizes, 30-68×18 for the front wheels and 31-71×18 for the rear. The company says the decision to fit an 18-inch tyre is in line with its desire to see as many parallels as possible between racing and road tyres, an arrangement that enables new technologies developed for motorsport to be more swiftly carried over to road tyres.
