My BMW 520 came with 225/55 R17 tires from the factory, which are quite standard in size and provide stable driving performance. The grip is particularly good on highways, and the anti-skid effect in rainy conditions is also commendable. The rims are typically 17-inch with a sporty design. However, when replacing tires, don't just focus on the model. Remember to check the production date and brand, such as Goodyear or Continental, as these can affect comfort and noise levels. I usually maintain my tires by regularly rotating them, which helps extend their lifespan.

As someone who frequently handles car-related matters, the standard tire for the BMW 520 is 225/55 R17. However, higher trim versions may come with upgraded 18-inch rims, corresponding to the size 245/45 R18. The size directly affects handling and fuel efficiency—smaller tires are more fuel-efficient but less agile in turns, while larger ones improve handling but produce more noise. It's recommended to check the model year, as the manufacturer specifies the tire size on the door frame label when purchasing a new car.

When repairing cars, I often see BMW 520 models using 225/55 R17 tires. This specification indicates a width of 225 millimeters and an aspect ratio of 55%, which is suitable for daily driving. The size is crucial as it affects the suspension performance, ensuring a smoother ride over speed bumps. It's best to replace them with the same factory model when they age, to avoid tire imbalance that could cause vibrations or excessive wear.
