What is the tire model size for BMW 5 Series?
3 Answers
The BMW 5 Series is equipped with Hankook tires in the size of 245/45-R18, while some imported models feature 245/40-R19 for the front tires and 275/35-R19 for the rear tires. Here is some information about Hankook: 1. Hankook tires are one of the main products of Hankook Tire Co., Ltd. The company introduced advanced manufacturing technology from Hankook Tire Corporation of Korea and has obtained quality certifications including ISO-9002, QS-9000, VDA6.1, and CCC. 2. The company provides tire support for many large domestic automobile manufacturers, including major automotive groups such as FAW Group and Shanghai Volkswagen.
I just helped a friend change the tires on his BMW 5 Series a few days ago, and realized the tire specifications aren't fixed. My friend's 2020 530Li came with 225/50 R18 run-flat tires, while the 525Li parked next to it uses 225/55 R17. The key factors are your wheel size and specific model year configuration - base models often have 17-inch wheels, mid-range versions get 18-inch, and sport editions may go up to 19-inch. There's usually an original specification label on the door frame or inside the fuel filler cap - remember to follow this when replacing tires. Different sizes make quite a difference in driving feel: 17-inch offers better comfort, 19-inch provides stronger grip but requires caution over speed bumps, and while run-flat tires are noisier, their ability to run 80km after a puncture is very practical.
The BMW 5 Series tires we handle in the shop come in a variety of models, with common specifications including 225/55 R17 and 225/50 R18, while higher-end versions may use 245/45 R19. The specific model depends on the factory configuration. For example, the 530 Leading model often comes with 18-inch tires, whereas the 540Li typically uses different sizes for front and rear, such as 245 in the front and 275 in the rear. The most accurate method is to check the small print on the tire sidewall or the label on the driver's door frame. Once, a customer replaced their tires with a smaller size, resulting in the dashboard speed showing 5% faster than the actual speed, and they even failed the annual inspection. The factory-standard run-flat tires, although 30% more expensive than regular tires, make the trunk much tidier without a spare. It's recommended to rotate the tires every 20,000 kilometers to extend their lifespan.
