This specific designation refers to a tire size commonly used on heavy-duty trucks and some SUVs. The numbers and letter describe key physical dimensions and performance characteristics. “295” indicates the tire’s width in millimeters. “75” represents the aspect ratio, which is the ratio of the tire’s sidewall height to its width. “R” signifies radial construction, the standard for modern tires. “22” denotes the wheel diameter in inches. The “5” likely refers to a five-rib tread pattern, suggesting a design optimized for all-season traction and even wear.
Selecting the correct tire size is critical for vehicle safety and performance. Properly sized tires ensure optimal load-carrying capacity, handling, braking, and speedometer accuracy. Deviations from the manufacturer’s recommended tire size can negatively impact these factors and potentially lead to unsafe driving conditions. The evolution of tire technology, including advancements in materials and construction techniques, has resulted in sizes like this that cater to the increasing demands of larger, more powerful vehicles. These advancements improve fuel efficiency, traction, and overall vehicle control.
