Most blowouts are not from too much pressure but too little - that is why they added TPMS to all cars.

In the 70's I tested tires one summer for uncle sam - for blowout - you need close to 100 psi in a 32psi rated tire hitting a pothole at 45 mph.

You are safe filling any tire to the max pressure on the sidewall - if you can stand the ride.

I tried 40psi in the Dunlop rate 44psi but the civic wandered in the wind. 36psi is just right for me.
