Why tire maintenance is important

Tire Pressure Changes with Temperature
For every 10°C rise or drop in temperature, tire pressure increases or decreases by 0.07–0.14 kg/cm². Therefore, pressure must always be measured when the tires are cold. After measuring, be sure to replace the valve cap securely.

Before driving on the highway, always verify correct pressure. As a general rule, tire pressure should be increased by 10% for highway driving, as this reduces heat generated by rolling resistance and improves safety margins.

Uneven tire pressure between tires can cause irregular tread wear, affect vehicle handling, and significantly increase the risk of accidents.

Remove Debris from Tread Grooves
Over time, small stones, gravel, and other debris can become lodged in the tread grooves. If not removed, these can cause a rough ride and seriously damage the tire. On the highway, trapped debris is a particular hazard that can lead to a blowout. Check your tires regularly for foreign objects and clean them out promptly to keep the tires in good condition.

Monitor Tread Wear Indicators
New and worn tires differ greatly in traction and grip. Worn tires have much less grip and are prone to skidding. Replace tires according to their wear level. How do you know when to replace them?
Every main circumferential groove has a tread wear indicator—a small rubber bar with a trapezoidal cross‑section. When the tread wears down to the level of these indicators, the tire must be replaced. For wet‑weather driving, to prevent hydroplaning, tread depth should remain above 3 mm.

Rotate Tires Regularly
If you notice pulling to one side, a heavy steering feel, or uneven wear on one side of a tire, these are signs that a wheel alignment is needed. Because front tires wear faster than rear tires due to steering, regular tire rotation helps even out wear and extends tire life. For front‑wheel‑drive vehicles, industry experts recommend rotating tires every 8,000 km.

Repair Punctures Promptly
If you find a nail or other sharp object embedded in a tire, even if it hasn’t lost air, switch to the spare tire as soon as possible. A small puncture, left unattended, can eventually lead to a serious failure. Frequently inspect the entire tire surface for nails, screws, glass shards, stones, or other impacts—any of these hidden threats can cause a slow leak or sudden blowout.

Summary
Tire maintenance is important, but it doesn’t have to be complicated. Give your tires the attention they need, and they will perform reliably for you.
