What is the wheel size of the BMW 3 Series?
2 Answers
The wheel size of the BMW 3 Series is 17. Below is an introduction about BMW: Models: BMW is a German automobile manufacturer with a wide range of cars and SUVs in its lineup. Many BMW models have been locally produced in China, such as the 1 Series, 3 Series, 5 Series, X1, X2, X3, etc. The BMW 3 Series is a mid-size car from BMW, available in both standard wheelbase and long wheelbase versions. Engine: The domestically produced BMW 3 Series comes with three engine options: a low-power 2.0-liter turbocharged engine, a medium-power 2.0-liter turbocharged engine, and a high-power 2.0-liter turbocharged engine.
Over the past decade, I've repaired at least a hundred BMW 3 Series models, and there's no uniform standard for wheels. When I first worked on the 2005 model year, I even saw 16-inch small wheels, but now the new Shadowline editions come with 20-inch ones. The key to choosing wheels lies in the J-value and ET value. For example, the 325Li commonly uses 18×8J with 225 tire width, which is quite balanced. However, I advise owners not to casually change sizes. Once, I encountered a customer who forcibly installed 21-inch wheels, resulting in steering gear noise and tires constantly rubbing against the wheel arches. If modifications are necessary, it's best to keep the deviation within 3% of the factory specifications, otherwise, it affects the odometer accuracy and handling stability. BMW usually labels the original size on the door frame sticker or inside the fuel filler cap, so remember to take a glance when buying a car.
