The recommended tire pressure for most vehicles is between 32 to 35 PSI. However, one can go as low as 20 PSI, although it is not recommended. According to Force by Mojio, most passenger car tires require 32 psi to 35 psi, so 28 psi is too low for tire pressure.
Low tire pressure can have several negative effects, including fuel inefficiency, premature and uneven wear, frequent flat tires, compromised handling, and tire failure and blowouts. The most dangerous risk associated with low tire pressure is tire blowouts, which can cause the driver to lose control of the vehicle and lead to accidents. Blowouts are more likely to occur at higher speeds, making them extremely dangerous and life-threatening.
To avoid low tire pressure, it is important to regularly check tire pressure and fill each tire with the proper amount of air.
