Most 4S shops do not repair tires. Here are the tire repair methods: 1. Cold and hot patching: The cold patching method uses cold patching film and glue to cover the holes on the original airtight layer. Since it is repaired directly without heating, it is called cold patching. The hot patching method also uses the above tools, but ensures the correct bonding of the adhesive under heating conditions. However, high temperatures may have some unnecessary effects on the tire rubber. 2. External patching strips for repair: This method can only repair small nail holes and is very convenient, but the service life is not long, and it will heat up and soften to prevent gas inside the tire from leaking through the nail holes. 3. Tire repair machine for repair: This is generally a tire repair and inflation all-in-one machine, which can avoid tire replacement, but it is generally only suitable for small nail holes.

I've been driving for over ten years and often go to 4S shops for and repairs. Regarding tire repairs, most 4S shops provide this service, but it depends on the extent of the tire damage. For small punctures like nails or tiny holes, they can fix them using professional methods such as hot patching or mushroom plug repairs, which are quick and reliable, taking about half an hour. However, if the damage is on the sidewall or too large, it can't be repaired, and for safety reasons, you’ll need to replace the tire. I remember once when my tire was cut by a metal shard—I took it to the 4S shop, got it repaired, and they also performed a dynamic balance test, making my drive much more secure. The downside is that it might be a bit more expensive than outside shops, so I recommend calling ahead or driving over directly. Since tire issues affect handling and fuel efficiency, it’s best not to delay repairs.

From experience, 4S shops can usually repair tires and handle small punctures without issues. They use professional methods for quick fixes to ensure no air leakage. If the damage is small and on the tire crown, it can be repaired; sidewall damage requires replacement. Check your tire condition and address serious problems immediately.

Safety comes first. If there's an issue with my tires, I head straight to the 4S store or a specialized repair shop. They can patch tires but rigorously inspect the damage. For example, sidewall cracks require replacement, otherwise it's dangerous at high speeds. After patching, they test the balance to ensure smooth driving. Don't skimp or handle it carelessly to save money.
