Setup: Professional installation is strongly recommended for this tire to ensure proper mounting, balancing, and alignment. Incorrect installation can affect vehicle handling, tire wear, and safety. Always ensure tires are inflated to the vehicle manufacturer's recommended pressure, found on a placard inside your vehicle's door jamb or owner's manual. Compatibility: This specific tire, size `225/65/17` with a load index of `102` and speed rating `H`, must match your vehicle's specifications. Consult your vehicle's owner's manual or a tire professional to confirm compatibility. The speed rating `H` indicates a maximum speed of 130 mph (210 km/h), and the load index `102` supports up to 1874 lbs (850 kg) per tire. Care: To maximize the lifespan and performance of your Wildpeak A/T AT3WA tires, adhere to a routine maintenance schedule. Regularly check tire pressure, at least once a month and before long trips, including your spare. Rotate your tires every 5,000 to 8,000 miles (8,000 to 13,000 kilometers) to promote even wear. Periodically inspect the tread for any signs of damage, punctures, or uneven wear patterns. Keep tires clean, especially after off-road use, to prevent debris from degrading the rubber.
