When it comes to tire sizes, 245/75R16 contains specific information about construction and dimensions. Each number and letter tells you exactly what to expect from the tire's performance and fitment. Breaking down this code helps you understand the tire you're considering for your vehicle.
The number 245 represents the tire's section width measured in millimeters from sidewall to sidewall. This 9.65-inch width provides substantial road contact for enhanced traction and stability, especially important when hauling loads or driving off-road.
Wider tires like the 245mm create a larger contact patch with the road surface. This increased contact improves handling characteristics and traction but comes with higher rolling resistance that can affect fuel economy. The 245mm width strikes a balance between performance benefits and efficiency considerations.
The 75 following the slash indicates the sidewall height as a percentage of the tire width. This means the sidewall measures 75% of 245mm, calculating to 183.75mm or about 7.23 inches.
Higher aspect ratios like 75 prioritize ride comfort through enhanced shock absorption. The taller sidewall acts like additional suspension, smoothing out road irregularities. Lower aspect ratios provide sharper steering response but transmit more road vibration to passengers.
For light trucks, SUVs, and vans that encounter varied driving conditions, the 75 aspect ratio delivers the versatility and comfort these vehicles require.
The "R" designates radial construction, now the standard for modern tires. Radial tires feature internal plies arranged perpendicular to the direction of travel, typically using polyester, steel, and fabric cords coated with rubber.
This construction method offers superior road grip, lower rolling resistance for better fuel efficiency, enhanced ride comfort, and improved durability compared to older tire designs. The flexible sidewall combined with a stable tread creates better overall performance characteristics.
The final number specifies the wheel diameter in inches that the tire fits. This measurement represents the distance between bead seat areas where the tire seals against the wheel. Sixteen-inch wheels are common on many light trucks and SUVs.
The total tire diameter combines the 16-inch wheel with twice the sidewall height (7.23 inches × 2), resulting in a 30.47-inch overall diameter. This measurement affects ground clearance, gear ratios, and speedometer accuracy.
These four components work together to describe the tire's dimensions and construction, allowing precise matching between tires and specific vehicle requirements.
