Tire Pressure?

So max tire pressure as posted on sidewall is 51psi for fronts. Reccomended per gas sticker is 42 and on the road my tires hit 50. Cold pressures are measuring higher than recommended. Also felt like there was not enough grip car felt sort of unplanted. Should I bleed off some air? This is the warmest day so far this Spring by a good margain and I definately felt car was different. I’m sort of uncomfortable hitting max recommended pressure although I realize that value is COLD and tires were baking in the sun all day.

Tires should heat up roughly 3-4 psi from cold temp to on the road temp. Take 5-7 psi out and give that a shot.

So I did lower it to the recommended PSI and it does handle much better now.

I think they overinflated for transport.
