I think the premise for overinflation,is that it would reduce tirewall cyclic deflection and deformations at the tread face which effect RR,and which would perhaps forestall standing wave.There must be something to higher pressures,as LLR concept tires all have elevated pressures,and are designed "AROUND" this parameter.-------------------------------the thing about contact patch as associated with traction may not hold up,as Don Schroeder of CAR and DRIVER conducted tire tests on a Corvette,at Chrysler Proving Grounds 300-foot skidpad,and found that when one of the very wide front tires was replaced with the very skinny compact spare,the car performed to essentially the same maximum G-force,in spite of the compromised contact patch.The skinny tire did remarkably effect turning response.
