How often should SUV tires be replaced?
2 Answers
SUV tires generally need to be replaced every 3 to 4 years or after driving 50,000 to 80,000 kilometers. Below are the criteria for determining when to replace car tires: Tire tread wear level: There are tread depth indicators in the tire grooves, approximately 1.6mm high. When the tread wears down to the level of these indicators, the tires should be replaced. Under normal usage, tires typically last about 50,000 to 80,000 kilometers. Once this mileage is reached, owners should have their tires inspected. Observe the aging of the tire surface: The aging of the tire surface is closely related to the duration of use and the operating environment. Harsh conditions or prolonged inactivity can accelerate tire aging, which manifests as extensive cracking on the tread and sidewalls. Once cracks appear, the tires should be replaced as soon as possible, even if they haven't reached their normal lifespan, as cracked tires significantly increase the risk of blowouts at high speeds. Damage to the tire sidewall or bulging: Under normal driving conditions, the sidewalls are rarely damaged. However, some drivers may scrape the sidewalls while parking or overcoming obstacles. If the sidewall is damaged, the tire cannot be repaired and must be replaced. Bulging indicates that the fabric or metal reinforcement layers in the sidewall have broken, posing an imminent risk of blowout, necessitating immediate replacement. Excessive tire repairs: Vehicles operating in poor conditions are more prone to punctures. It is not advisable to repair the same tire too many times. Generally, if a tire has been repaired more than three times, it is recommended to replace it, as excessive patches significantly increase the risk of failure during use.
When it comes to replacing SUV tires, you can't just rely on time alone. Having driven for over a decade, I believe a comprehensive approach is necessary. Tires themselves have wear indicators—those small raised blocks in the grooves. If they’re worn flat, it means the grip is compromised, and replacement is a must. Mileage also serves as a useful reference. For those who mostly drive on city roads, replacement is typically needed around 50,000 to 60,000 kilometers. But in my case, since I often drive on rural or muddy roads, the tires wear out severely before even hitting 40,000 kilometers. If you notice cracks or bulges on the sidewalls, immediate replacement is non-negotiable. Don’t overlook rubber aging either—even if you drive sparingly, tires older than five years should be checked for elasticity and hardness. During car washes, you can quickly check by inserting a coin into the tread grooves. If the national emblem is fully visible, it’s time to prepare for a tire change. Safety should always come first.
