Can you put a tube in a knifed car tire?

Answer 1

Of course you can. This is a sidewall slice I assume on a radial ply tire? Prep and repair the sidewall and apply a sidewall patch to the damaged area. Remove the air stem from the rim and use baby powder to coat the interior of the tire. This is important to keep the tube from being "pinched" during inflation. put baby powder all over the tube and install the tube. Inflate as to the recommended tire pressure listed on the tire, being careful to not pinch loose tube material in-between the bead of the tire and the rim. Be aware that the tire is damaged but usable and install on the rear and do not drive in such a manner as to over stress this tire and it will last until it is worn out. Side wall repairs are not recommended.

He is correct, but if we all avoided things that were not recommended, We would never leave our houses, and there are millions of things that could happen in your own house that are not recommended.

I gave an answer that has been done millions of times, sucessfully. He gave you the politically correct short answer.

That's the trouble with this country, too many of us are rolling over without "trying". The method I suggested will cost you a few bucks and some time. If you follow his advice and replace the tire, it is not recommended to run one new tire with three used tires, so you need to buy an entire new set of tires.
