What does 22560r18 mean for tires?
2 Answers
225/60/r18 indicates that the tire width is 225mm, the aspect ratio is 60%, the tire structure is radial, and the rim diameter is 18 inches. Below is relevant information about car tires: Precautions for tire use: Regularly check the tire surface for cracks, deformations, and other defects. Park on level ground and avoid parking on roads with large, sharp, or jagged stones. Do not use water to cool overheated tires. Tires can overheat during prolonged or high-speed driving in summer, leading to increased pressure. In such cases, stop to let the tires cool down. Never release air to reduce pressure or splash water to cool them, as this can cause abnormal aging of the tire rubber. Main functions of tires: Support the entire weight of the vehicle, bear the car's load, and transmit forces and moments in other directions. They transfer traction and braking torque, ensuring good adhesion between the wheels and the road to enhance the vehicle's power, braking, and off-road performance. Together with the car's suspension, they cushion impacts during driving and dampen resulting vibrations.
That tire code 225/60R18 was confusing when I first changed tires, but after researching I understood: 225 represents the tire width of 225mm - the wider the tire, the more stable and grippy it feels; 60 is the aspect ratio percentage, meaning the tire's sidewall height is 60% of its width - higher numbers mean thicker tires with better cushioning and comfort; R stands for Radial construction where internal cords are arranged radially, now the standard; 18 is the rim diameter in inches. This size commonly appears on SUVs or sporty cars - I've tried them and the handling feels great, but be careful to choose the correct size otherwise the odometer reading will be inaccurate affecting safety - recommend getting professional shop inspection for proper fitment. The aspect ratio significantly impacts driving experience - I once chose tires with lower ratio and felt much more bumpiness over speed bumps, even had to adjust the suspension.
