Frequently Asked Questions
This is a tire size in which the tread is 275mm (approximately 10.8 inches) in width, the sidewall is 45% of the tread width, and the rim is 20 inches in diameter. This tire size is available for luxury sports cars, high-performance sedans, and some high-performance SUVs. Thus, it provides maximum handling on paved roads.
This tire size is approximately 28.3 inches or 719 millimeters in overall diameter. It has tread width of 275 millimeters and the height of 45% of the tread width, as well as the 20-inch rim diameter. The larger overall diameter provides a wider footling on the road for better traction due to the increased sidewall height important for faster cars.
This is the tire size information. The R here is radial and the number tells the width of the tire’s tread the measurement comes in mm. The 45 is the height of the tire’s side wall as a percentage of the width of the tire’s tread. The 20 is the diameter of the wheel/rim in inches. Therefore, this means a radial tire 275 mm in width with a 20-inch wheel diameter with side walls that are 45 percent of the tire’s width in mm.
The recommended pressure will be different for each vehicle and depend on the rated load as well as the manufacturer. Nonetheless, in most cases, the psi usually ranges from 30 psi to 35 psi when the tires are cold.
Regular tire rotation ensures even tread depth, prolongs tire life, and boosts performance. Most experts recommend 6,000 to 8,000 miles and follow your automobile manufacturer’s suggestions.
