What are the three-guarantee regulations for 4S car tires?

[VonBrooke]

4S car tire three-guarantee refers to warranty, replacement, and refund, with the following regulations: 1. After purchasing tires: If quality issues are found before actual use, new tires can be exchanged. For appearance quality issues, both parties can negotiate a solution. 2. During use: If quality issues are found, the compensation standard is calculated based on the wear depth of the tread pattern. The specific regulations are as follows: (1) If the remaining tread depth is more than 70%: Free replacement of new tires. (2) If the remaining tread depth is 60%-69%: Replace new tires at 30% of the factory price. (3) If the remaining tread depth is 50%-59%: Replace new tires at 40% of the factory price. (4) If the remaining tread depth is 40%-49%: Replace new tires at 50% of the factory price. (5) If the remaining tread depth is 30%-39%: Replace new tires at 75% of the factory price.

Last time I changed tires, I specifically researched this. The tire warranty at 4S shops is different from regular auto repair shops. First, the 'repair' coverage refers to issues like tire bulging or abnormal wear—the 4S will inspect and fix it for free. The 'replacement' is the most practical benefit—if the tire cracks or deforms before reaching 5,000 km, they have to give you a new one. 'Refunds' are rare unless you find sand holes or sidewall deformation while the tire hairs are still intact right after picking up the car. The key is to check the warranty card's duration—standard tires usually cover two years or 50,000 km, whichever comes first. Keep the receipt safe; my neighbor once lost proof and couldn’t claim rights. Actually, many 4S shops offer free tire pressure monitoring services as a hidden perk.

Buddy, I often drive on highways and have encountered tire issues several times. The 4S shop's tire warranty generally has three layers of protection: free replacement for bulging or cracking due to quality issues; reinstallation if damage is caused by improper installation; and returns within seven days if you find the wrong model or size discrepancies. Pay special attention to the warranty duration—original tires from brands like Hankook or Bridgestone usually come with a two-year warranty, while Michelin's premium series can extend up to three years. It's advisable to have technicians check the tire wear during each maintenance service and document it, making it easier to provide evidence if issues arise. Also, avoid getting tires patched outside the 4S shop, as it may void the warranty.

Based on my experience, the core of 4S tire warranty boils down to three points: free replacement for non-human damage within one year, free repair for quality issues within two years, and free return for size errors within one month. The key is to keep the work order properly, as some shops may prorate replacement costs based on mileage—this must be clarified upfront. Nowadays, most brands have clear claims standards for tread cracks, such as only accepting cases exceeding 3mm. A special reminder: always inspect your tires promptly after driving in the rain, and small stones stuck in tire grooves are considered normal wear.

A couple of days ago, I went to the 4S store to dispute a bulge in my car's left front tire. The claims specialist explained the rules in detail: First, the warranty covers tread separation and steel belt breakage; replacement is for manufacturing defects like inner liner detachment; refunds are only for unused tires within 30 days. They measured my tire tread depth with a vernier caliper on the spot and calculated the compensation amount based on a 10% monthly depreciation rate. A reminder to everyone: always check the tire production date code when picking up your car—a four-digit DOT code older than two years is considered a stock tire. Also, keeping photos of the rims during the claim process is crucial, as the 4S store uses them to determine if the damage was caused by external force.

Both of our family cars had their tires replaced at 4S shops. Here’s a summary of the practical three-guarantee policy: The repair guarantee covers slow air leaks or minor deformations; the replacement guarantee handles bulging issues within three months, but costs are deducted based on mileage; the refund guarantee is mostly effective only at the time of delivery. It’s advisable to focus on the claim conditions—for example, Dunlop requires a tread depth of at least 1.6mm to process a claim. Last time, a friend’s tire sidewall cracked, and the 4S shop refused compensation citing curb impact, but providing surveillance footage could have helped appeal the decision. It’s recommended to take photos of your tires quarterly for records and avoid hard braking within the first 500 kilometers after tire replacement.
