How to Solve the Problem of Excessive Tire Noise on the LaCrosse?
2 Answers
The solutions to excessive tire noise on the LaCrosse are: 1. Remove debris such as stones from the tire treads, which significantly helps in reducing tire noise, especially when larger stones are stuck in the treads, as they cause loud noise when rubbing against the road; 2. Cleaning the tires can also help reduce noise; 3. Perform dynamic balancing or four-wheel alignment on the tires; 4. Check if the tire pressure is within the normal range. The LaCrosse is a mid-to-high-end sedan launched by Shanghai GM, with dimensions of 5005mm in length, 1858mm in width, and 1500mm in height, a wheelbase of 2837mm, a front suspension type of MacPherson independent suspension, and a rear suspension type of multi-link independent suspension.
I've been driving a Buick LaCrosse for several years, and the tire noise is indeed quite annoying. First, check the tire pressure. The Buick manual recommends 2.4 bar for the front tires and 2.3 bar for the rear tires. Both overinflation and underinflation can amplify noise. If the tires are severely worn and the tread is smooth, the noise will naturally be louder, and it's time to replace them. I've switched to Michelin Primacy series, which offer good noise reduction, costing about 1000 yuan per tire and reducing several decibels. Road conditions also have a big impact, so try to avoid bumpy roads and maintain a steady speed while driving. During regular maintenance, check the suspension system, as worn-out shock absorbers can transmit vibrations and noise. Replacing them costs a few hundred yuan. In short, from simple checks to tire replacement, taking it step by step can make the ride much quieter.
