Q: How about tire pressures? Would that be part of your set up for mechanical grip?

A: Tire pressures are vital to mechanical grip but Pirelli does give guidelines to minimum start pressures and hot pressures.  At a track like Daytona this is vital as the high loads can damage the tires on low pressure which is why you have seen so many punctures at the test and race on certain cars.  We are always trying to push the envelope.
