Frequently Asked Questions
The overall diameter of a 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. Thus, it is suitable for high-performance cars.
This tire size does have many benefits for high-performance applications. Firstly, wide tread width and low profile sidewall provide better grip, stability during cornering, and responsiveness. Second, 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” and more aggressive look.
About the miles, you may so rotate a 305/40R22 tire, it should be top after recently of 5,000 to 8,000 miles on the most magnificent estimate or your vehicle’s owner’s command. It helps to develop your tire treads’ mile reality, which is virtually identical so that you can substitute all four.
A tire size designation means a certain set of dimensions. Thus, 305 stands for the tread width in millimeters. As for 40, it is the aspect ratio—a percentage of the sidewall height to the tread width—and R is for Radial construction. Finally, 22 stands for the rim diameter in inches.
The optimal air pressure for a tire of any size may vary depending on the particular vehicle and loading, as well as the tire manufacturer’s recommendations. However, in general, the air pressure for cold 305/40R22 wheels is normally 30 – 35 PSI.
