Maintaining your tires is crucial for improving gas mileage, extending tire life, and ensuring a smoother ride. Regular inspection for wear and proper pressure is essential for safe driving. To maintain your tires effectively, use a tread depth gauge or a penny to check tread wear, ensuring it doesn't reach the wear bars. Look for uneven wear patterns across tires, indicating potential alignment or suspension issues. Additionally, check tire pressure regularly when tires are cool, comparing readings with recommended levels in your owner's manual. If adjustments are needed, use an air compressor to add or release air accordingly. Consider nitrogen filling for improved fuel economy, extended tire life, and enhanced ride quality. Rotation every 10,000 miles is recommended for even wear. Regular tire maintenance saves money and keeps your vehicle performing optimally.
