Tire rotation is crucial in extending the lifespan and maintaining the performance of your Toyota 4Runner's tires. By rotating your tires, you ensure even wear across the tread, consistent performance and high traction, improved fuel efficiency, a smoother and quiet ride, and lower running costs.
For convenience, you can do that at every oil change or at 5,000-8,000-mile intervals. Toyota recommends an oil change every 7,500 miles for synthetic oil and 5,000 miles for mineral oil. Regardless, I recommend rotating the tires with the oil change, as it will be cheaper and quicker.
Since the 4Runner is a 4x4 SUV, I recommend the "X" rotation pattern, where you put right front to the left rear, left front to the right rear, right rear to left front, and left rear to the right front.
You can also ask your tire technician to re-balance the tires at every rotation, as that will help with alignment and ensure your 4Runner runs smoothly.
