The instructors at Queensland Raceway do a big "safety talk" for anyone running street tyres on the race track.
Inflate the tyres to approx 40lbs. Hot....in the case of. Car sliding sideways,it will stop the tyre from rolling off the rim,wheel digging in to the track,and possible roll over.
But it's up to you....
I'm not the one driving the car,and I can see what they're getting at,but I also feel,you'd lose some grip without the tyre flexing a bit more.
Too many experts around to get the right answer I suppose.
Cheers,
