Frequently Asked Questions
The overall diameter of this tire is about 30.5 inches or 775 millimeters. It has a tread width of 305 millimeters, a sidewall height of 40% of the tread width, and a 22-inch rim. It results in a wider contact patch and a higher grip on the road, making it particularly suitable for high-performance cars.
This tire size has many benefits for high-performance vehicles. Firstly, the wide tread width and low profile sidewall provide better grip, stability during cornering, and responsiveness. Secondly, a larger contact patch and specialized UHP tire compounds provide superior braking performance and improve heavy vehicle control. Lastly, the low profile and larger overall diameter of the tire improve the vehicle’s aesthetics, giving it a sportier look.
You should rotate your 305/40R22 tires about every 5,000 to 8,000 miles or every six to 12 months. Regular tire rotation helps ensure uniform tread wear on each of the four tires and optimizes traction, handling, and fuel efficiency for your vehicle.
305 stands for the tread width in millimeters. 40 is the aspect ratio, a percentage of the sidewall height to the tread width. R is for radial construction. Finally, 22 stands for the rim diameter in inches.
The optimal air pressure for a tire of any size will vary depending on the particular vehicle and load, as well as the manufacturer’s recommendations. However, the air pressure for many 305/40R22 tires is normally between 30 and 35 PSI when cold.
