Is It Normal for the Passat to Have Increased Tire Noise After Front-to-Rear Tire Rotation?
2 Answers
Passat tire noise is normal after front-to-rear rotation. Situation Description: Increased noise after tire rotation is quite normal, as there is a 100-kilometer adaptation period post-rotation. The original tire positions had uneven wear, and the new positions will have slightly different contact angles, naturally resulting in different noise levels. The purpose of tire rotation is to adjust these angles to achieve more uniform wear. Cause Analysis: Due to varying operating conditions and loads, tire tread wear differs slightly between tires. Tire rotation aims to reduce tread wear discrepancies and extend tire lifespan. Some noise may occur after rotation but will diminish with use over time.
Increased noise after tire rotation is usually normal, especially for models like the Volkswagen Passat, as the front tires bear more weight and steering force, leading to faster wear. When the less worn rear tires are moved to the front, the way they contact the road changes, which may increase rolling noise. I've experienced a similar situation with my own car, and the noise stabilized after a few days. However, if the noise persists, it's important to check for issues like uneven tire pressure, irregular wear, or physical damage, as these can affect driving comfort. Additionally, regular tire rotation every 8,000 kilometers is a good practice to extend tire life. If the problem continues, it's advisable to visit a professional shop for a wheel balance check to ensure there are no safety hazards.
