How to Deal with Excessive Tire Noise in the LaCrosse?
2 Answers
Solutions for excessive tire noise in the LaCrosse: First, check the tire tread. If the noise is caused by uneven tire wear, take the car to a 4S shop for a four-wheel alignment check. If the noise is not due to uneven wear, consider replacing the tires and adding sound insulation to the wheel arches. Car tires are one of the essential components of a vehicle, and driving safety heavily relies on them. Regular tire inspections are crucial, especially before driving on highways. The LaCrosse is a mid-to-high-end sedan introduced by Shanghai GM. The dimensions of this car are 5005 mm in length, 1858 mm in width, and 1500 mm in height, with a wheelbase of 2837 mm. The LaCrosse is developed based on GM North America's new Buick LaCrosse platform, utilizing the GMLAN 32-bit communication control system, which integrates major modules and sensors including powertrain, lighting, chassis, safety, and entertainment.
I've got plenty of experience with tire changes. Back when I drove a LaCrosse on the highway, I always felt this annoying buzzing in my ears. First thing to check is how long you've been using those tires - if the treads are worn smooth, they'll definitely be noisy. Switching to quiet tires makes a world of difference. The Michelin Primacy 4 or Continental CC6 are real noise-reduction experts, with their soft rubber compounds and specially designed tread patterns. Those holes in the wheel arches need attention too - I often help people with cavity soundproofing by filling them with foam sealant and adding a layer of sound-deadening mat, which muffles most of the stone impact noise. Don't overinflate your tires either - 2.3 bar when cold is sufficient, or up to 2.5 if you frequently carry a full load. After changing tires, always get them balanced - only properly balanced wheels rotate without vibration for quiet operation.
