Wheel misalignment is a silent tire killer, as it causes uneven tread wear and strains tire structure. Misalignment occurs over time from hitting curbs, potholes, or normal wear on suspension components. Signs include a vehicle pulling to one side, uneven tread wear (e.g., shoulder balding), or a vibrating steering wheel. Even minor misalignment can reduce tire life by 10-20%, so schedule alignment checks every 6 months or 6,000 miles—whichever comes first. After a major impact (e.g., hitting a deep pothole), have alignment checked immediately. Proper wheel alignment ensures tires make full, even contact with the road, distributing wear evenly and reducing stress on rubber and internal components. Investing in regular alignments saves money in the long run by extending tire lifespan and improving fuel efficiency.
