What to know when replacing tires
When shopping for tires, match the size to the OEM specification and consider speed rating and load index. If you want to preserve the car’s handling characteristics, sticking with the recommended size is best. If you have a different wheel set installed, verify compatibility and clearance before purchase.
Notes on tire maintenance and choice
All-season tires are commonly used for daily driving; seasonal and performance tires can change ride quality and grip. Regularly check tire pressure, tread depth, and rotate every 5,000–7,500 miles as recommended by Honda to ensure even wear and optimal performance.
