My tire is very good and was cut with a knife can the inner tube be used to save tire?

Unfortunately, if your tire has been cut with a knife, it is not advisable to use the inner tube to save the tire. The structural integrity of the tire has been compromised, and the inner tube alone will not be able to provide sufficient support and safety. Continuing to use a damaged tire can be dangerous and may lead to further damage or even accidents.

To ensure your safety and the proper performance of your vehicle, it is recommended that you replace the damaged tire as soon as possible. Do not attempt to use the inner tube alone as a temporary solution, as this may cause additional problems and put you at risk.

When replacing your tire, be sure to have it inspected and installed by a qualified professional. They can assess the extent of the damage and make sure that the new tire is properly mounted and inflated to the correct pressure. This will help ensure a safe and smooth ride for you and your passengers.
