Automotive maintenance: Understanding tire specifications and handling

Understanding tire markings and vehicle handling is essential for automotive safety and efficiency. Tire specifications follow an international standard, read from left to right, including width in millimeters, profile height, radial construction, rim diameter in inches, and load and speed indices.

For example, in a code like ‘205/55 R16 91V’, the number 91 indicates a maximum load capacity of 615 kg, while the letter V denotes a maximum speed of 240 km/h. It is critical that tire dimensions match the manufacturer's specifications to avoid safety risks.

When a vehicle pulls to one side on a straight road, it may indicate uneven tire pressure, misalignment, or issues with brakes and suspension. Differences in tire pressure can alter rolling resistance and cause steering deviations. Experts recommend checking tire pressure against the manufacturer's recommended values rather than the maximum pressure listed on the tire sidewall.
