Are there any vehicles where the max tire pressure indicated on the tires are actually safe for the vehicle? It seems the max pressure stated on the tire might be 50 psi or more but the vehicle calls for a cold pressure of 30 or 35 psi. If you were to put 50 psi in the tires, you'd probably run off the freeway due to lack of traction.

Tire pressure sticker info is for a vehicle that is loaded with passengers and luggage to the maximum limits and with a full tank of gas. Otherwise, a lower tire pressure is preferred for riding quality and tire wear.

Adjust your tire pressure according to the driver door's sticker, every car has different setting, that is the safest way to get maximum handling and tire life. at the bottom is the spare tire pressure
?
The max pressure shown is that which the tire carcass is tested to, and is nothing to do with what the car requires. The latter varies from car to car, even with identical tires, and the one for your car is what you must use.
The only time the max pressure is relevant is when overinflating the tire to seat the beads. It isn't even shown in most countries as it is pointless. Using it on the road will result in very poor grip, poor wear, increased risk of blowout and a hard ride.

NEVER USE MAX PRESSURES when the Tyre gets hot the Pressure goes up above max pressure and because the tyre is hot it is soft and you can have a Blow out when the Tyre Leaves the Rim Use your Handbook or 30psi if too soft go up in 2 psi increments until it feels compfortable
My 220 Sb Mercedes said 28 PSI for Cross-ply tyres and nothing about Radials i fitted 195 70 R 14found 30 psi rear and 28 Front a Nice ride and tyres lasted

The MAX PSI on the tire sidewall is only for when installing the tires on the rim to seal the bead!
