What is the proper tire inflation pressure for a 2001 Dodge Neon?
Check the sticker on the drivers door jamb
The tire will have the maximum allowable pressure printed on the sidewall of the tire. If your vehicle does not have the original equipment tires on it, you wouldn't be filling the tires to the proper pressure anyway. Look on the sidewall of the tire, it's mandatory for tire producers to label the tire with the proper inflation rate
