Seriously, it is on the tire itself .....

If you want to die a horrible flaming death in a car crash, use the air pressure on the tires on a rear-engine VW. Rear-engine and mid-engine cars are not like front-engine cars - for safe handling, you need either more air pressure or a wider tire on the back of the car than on the front. Corvairs were especially prone to having tire pressure make the car go out of control; there is more weight in the back of a Corvair than a Bug because the engine is heavier, and the dealers didn't tell people this had to be done. (More than likely, they didn't know.) Rear engine sports cars use wider tires on the back - Porsche 911s and Ferraris use 20mm-wider tires on the back, and Lamborghinis use 120mm wider tires on the back. This is why. It's not because wider tires on the back make the car look better. (I checked tirerack.com; they sell a "matched tire set" for Lamborghinis. They want $291 per tire for the fronts and $751 per tire for the rears...I guess they figure if you can afford the insurance on one of those cars, you can afford $2100 for tires.) Volkswagen used the same tire size on both ends, so we get our safety through differential tire pressure.
The easiest way to remember it is, the fronts need 10psi less than the rears. I like running 18psi in front and 28 in back. Put 28 in the spare and paint the wheel red so you remember to get it off of there when you get the other tire fixed.
If you want to go the other way - running wider tires in back with the same air pressure at both ends - you can buy wider fenders. The wheel that comes on a Bug is 15" x 5.5" with a 4x130mm bolt pattern; as long as the bolt pattern matches you can buy wider wheels to fit. Try a 15" x 6.5" wheel; that should give you a good safe ride for not an outrageous price.
Air leaves a tire when the tire valve is open due to the pressure. The pressure outside of the tire is lower than the pressure inside the tire.
Air leaves a tire when the valve is opened due to the pressure difference. Since the tire has more pressure than the air outside, the tire air will escape until the pressure equalizes.
A 1967 VW beetle doesn't have a radiator you nit wit, ITS AND AIR COOLED ENGINE!!!!!!!!
Air rushes out because it is under pressure. Once there is no longer any pressure in the tire the air will stop flowing out. However there is still air in the tire it is just equal to the pressure outside.
Because the air inside the tire is under pressure. Gas always flows from a region of higher pressure to a region of lower pressure. As the pressure inside the tire is greater than the pressure outside, the air always comes out of the bicycle tyre.
Air pressure is the same throughout the tire.
Air pressure is maintained by a good seal between tire edge and rim.
The correct air pressure for your 2003 Road King standard tire is 18 pounds. The tire air pressure is dependent upon the type of tire.
The best air pressure, for your 1999 Toyota, is dependent upon the type and manufacturer of the tire. The best air pressure will be the recommended air pressure by the tire manufacturer.
The air in the tire is becoming heated due to the tires friction on the road surface. Heated air increases the pressure in the tire
Tire air pressure is dependent upon the size and type of tire. The 1999 Nissan Altima standard tire air pressure is 32 pounds.
When a tire runs on the road friction makes it hot, then air pressure increases.
