Frequently Asked Questions
This tire measures roughly 25.3 inches in outer diameter when installed and fully inflated on a 17-inch rim. The tread is 9.6 inches wide, and the sidewall height from the rim to the tread is about 5.5 inches.
To ensure even tread wear on all four tires, most vehicle manufacturers suggest rotating every 5,000–8,000 miles. However, optimal rotation intervals may differ depending on your driving style, vehicle weight and wheel alignment settings.
This is the tire size information. The first number 245, is the tire tread width in millimeters. The second number 45, is the aspect ratio, which means that the sidewall height of the tire is 45% of the tread width. “R” means that the tire is radial, and 17 is the wheel diameter in inches for which the tire was made.
Under normal circumstances a tire’s cold inflation pressure tends to be between 30 and 35 PSI. The ideal pressure can be above or below this range, depending on the vehicle’s make, model and loading. Refer to the tire information placard on the doorframe of your vehicle or the owner’s manual for the recommended pressure from the manufacturer.
The 245/45R17 is a low-profile tire size. It has a 245mm tread width, a short 45% aspect ratio for the sidewall height, a radial construction style, and is designed to fit on a 17-inch diameter wheel.
