It is vital to maintain proper tire pressure for 2018 BMW 320i tires. Low tire pressure will result in tire underinflation while high tire pressure will result in tire overinflation, which can decrease fuel efficiency, lead to uneven tire tread wear and reduce tire life, compromise tire safety and cause tire blowout. Check 2018 BMW 320i tire pressure regularly, and monitor 2018 BMW 320i tire inflation levels to avoid driving with overinflated or underinflated tires.

Tire inflation value listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not the recommended tire pressure for 2018 BMW 320i. Use 2018 BMW 320i recommended tire pressure settings listed on the tire pressure chart found in 2018 BMW 320i owner's manual, on a sticker on driver's door or door jam, inner trunk lid, in the console or on the fuel door. Recommended tire pressure for your 2018 BMW 320i tires will be listed in one of the following pressure units: psi (pounds per square inch), bar or kPa (kiloPascals). Pay attention as your 2018 BMW 320i may have different recommended tire pressure values for front and rear tires, especially if equipped with staggered tires. Keep your 2018 BMW 320i tires inflated at recommended tire pressure levels at all times for your driving comfort and safety.

If you replace 2018 BMW 320i original equipment tires or switch to plus size tires, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for your new 2018 BMW 320i tires. 2018 BMW 320i tires with the same load index, regardless of tire size, may carry the same load, but 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 2018 BMW 320i owner’s manual for any specific safety advice regarding the application of 2018 BMW 320i replacement tires.
