The level ground will also be perfect as it’s going to prevent the car from rolling. Also, a straight road stretch is better than curved as the coming traffic can likely see you.

Step 2: Turn the Hazard Lights On and Put Parking Brake:

The hazard lights also called “Flashers” are going to help other vehicle drivers to see you. Also for avoiding any kind of accident, make sure that you are turning it on as soon as you can when you realize that there is a need for pulling over.

The only negative of using tire sealant is that it may damage the monitoring system of the tire. This can later make replacement tricky as it can cling to the wheel. 

  • Just pump the tire sealant in the tire through the stem opening.
  • The vehicle has to be supported through a jack all this while.
  • Now follow the packaging instructions that give information on the amount of sealant required for each tire.
  • Now check the tire pressure so that you are sure of the balance once the sealant is applied. In case the sealant gets a puddle at the bottom, there will be a probability of imbalance in case you move ahead on uneven terrain or at high speeds.

Key Note:

Keep in mind that making use of less sealant than the recommended amount will reduce the efficacy because the tire won’t have enough tire sealant that can stop the puncture.

Method 2: Plugging tire while on the wheel

This can be an alternative and a better option over sealants. Keep in mind that this will be a temporary fix. You can push a plug inside the tire. This will be a good method in case there isn’t any internal damage. 

If you find that there is some kind of internal damage, don’t even try this method.
