How do you fix a puncture on a car?
Herein, how much does it cost to fix a puncture?
If you catch a puncture early, the repair should cost between $15 and $30. Run-flat tires generally call for complete replacement. Tire plug kits are relatively inexpensive if you know how to do the fix yourself. You can find them priced from $10 to $20.
In this regard, is plugging a TYRE legal?
A tyre that's been repaired should last until the tread has worn down to near the 1.6mm legal minimum and the tyre is replaced. Some unscrupulous tyre retailers might even fix a puncture by fitting an inner tube, which is totally against any guidelines.”
While it may be safe to drive with a slow puncture it is always recommended that you get the tyre repaired or replaced as soon as possible. The loss of pressure will be small at first, but continual tyre wear will eventually lead to a larger leak, more than enough to affect your car's handling and safety.
