BMW 128i Tire Pressure

It is important to maintain proper tire pressure for BMW 128i tires. Low tire pressure will result in tire underinflation, and high tire pressure will result in tire overinflation, which can compromise tire safety, cause tire blowout, decrease fuel efficiency, cause uneven tire wear and reduce tire tread life. Check BMW 128i tire pressure regularly, and monitor BMW 128i tire inflation levels to avoid driving with overinflated or underinflated tires.

Tire inflation value listed on tire sidewall is a maximum tire pressure the tire can be inflated to, and not the recommended tire pressure for BMW 128i. Use recommended tire pressure listed on the tire pressure chart found on a sticker on driver's door jam or in BMW 128i manual. Recommended tire pressure for your BMW 128i tires will be listed in one of the following pressure units: psi (pound per square inch), bar or kPa (kilopascals). Pay attention as your BMW 128i may have different recommended tire pressure values for front and rear tires. Keep your BMW 128i tires inflated at recommended tire pressure levels at all times for your driving comfort and safety.

If you replace BMW 128i original equipment tires with optional tire sizes or you switch to plus size tires, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for new tires on your BMW 128i. BMW 128i tires with the same load index, regardless of tire size, may carry the same load, but not always, and they may require substantially different inflation pressures. Tire load index may not be used independently to determine replacement tire acceptability for load capacity. An equal or greater load index does not always correspond to equal or greater load capacity at all inflation pressure settings.

Always refer to the BMW 128i owner’s manual for any specific safety advice regarding the application of BMW 128i replacement tires.

BMW 128i replacement tires must have equal or greater speed rating compared to the original equipment tires if your BMW 128i speed capability is to be maintained. It is recommended that tire installers refer to the BMW 128i owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your BMW 128i replacement tires have a lower speed rating than the original equipment tires, the vehicle’s speed must be restricted to that of the replacement tires.

Original equipment tires that come on your BMW 128i will have the proper tire load index, so stick to that number or higher when you replace them with new tires. Tire load index tells you how much weight your tire can carry. Putting too much weight on your tires will overload them, and can cause tire damage, premature tire wear or even tire blowout. Refer to your BMW 128i manual to find its original equipment tire sizes and their load ratings.

BMW 128i tire pressure changes with temperature, so check your BMW 128i tire pressure when outside temperature goes up or down. During colder months when temperatures drop, BMW 128i tire pressure will decrease also by approximately 1 psi for each 10 degrees Fahrenheit. Maintain proper BMW 128i winter tire pressure by adding air to your tires as needed to the recommended tire inflation levels.

BMW 128i tire pressure should be checked when tires are cold, after your vehicle has not been driven for at least three hours. It is best to check your tire inflation pressure in the morning, after the vehicle has been parked overnight, using a reliable tire pressure gauge.

If your BMW 128i is equipped with tire pressure monitoring system (TPMS), pay attention to low tire pressure warning light being on. Ensure your tire pressure sensors are working properly to stay alert and enjoy a safe ride. If your tire pressure warning light is on, check front and rear tires to make sure they are properly inflated.
