I've got a pair of Pirelli P Zero front tires (245/35-19) that were take offs from a 720s with delivery miles. Genuine tires, cheap price, buy them for spares so you'll have them when you need them since not being able to get tires seems to be a thing now.
You currently can't get these tires new, so here's some basically new. They were taken off a 720s with delivery miles. Front's for super series cars available now, rears available when Fedex decides to find the other tire.
