It is vital to maintain proper tire inflation pressures for BMW 128i tires. Low tire pressure and underinflated tires can lead to uneven and excessive tire wear, poor handling and reduced fuel economy. High tire pressure and overinflated tires can result in reduced traction, poor braking and can even be a cause of a tire blowout. Check tire pressure regularly and maintain correct tire inflation for BMW 128i to enjoy a safe and comfortable drive, save money on gas and keep auto insurance premiums low.
Recommended tire pressure for BMW 128i is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find BMW 128i recommended tire pressure in owner's manual or on a tire placard on the side of driver's door or door jam. BMW 128i tire inflation will be listed in psi (pounds per square inch), bar or kPa (kilopascals). Keep in mind that tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not necessarily the recommended tire pressure for BMW 128i. BMW 128i may have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.
To check BMW 128i tire pressure you will need to know its recommended tire inflation and a tire pressure gauge. Check tire inflation when tires are "cold" and have not been driven for at least 3 hours. Adjust BMW 128i tire inflation to the recommended tire pressure levels as needed by adding air with a tire inflator.
If you replace BMW 128i original equipment tires with optional or plus tire sizes, make sure to follow guidelines on how to apply tire load inflation tables when replacing BMW 128i tires to find proper tire pressure for new tires. Always refer to the BMW 128i owner’s manual for any specific safety advice regarding the application of replacement tires.
BMW 128i tire pressure fluctuates with ambient temperatures, so when temperatures drop tires may lose approximately 1 psi of air pressure for every 10 degree Fahrenheit decrease in temperature. During winter BMW 128i tires can be inflated 3 to 5 psi above the recommended tire pressure settings to compensate for lower temperatures. Never overinflate above psi indicated on tire sidewall. Make sure to check tire pressure regularly in the winter to keep tires properly inflated for a safe ride on snow and icy roads. Consult owner's manual for recommended winter tire pressure for BMW 128i.
If your BMW 128i is made after 2007, it should be equipped with tire pressure monitoring system (TPMS) that uses tire pressure sensors to alert the driver when tire pressure is low. When BMW 128i low tire pressure warning light is on, check all tires for low air pressure and inflate as needed. Refer to owner's manual on how to reset BMW 128i tire pressure monitoring system.
Select model year between 2008 and 2013 to find recommended tire pressure for BMW 128i tires to improve fuel efficiency, extend tire life and drive safely.
