When you noticed your car’s tyre is punctured:
1. Pull Over at A Safe Location Do not abruptly stop on the road. Pull over to the roadside or somewhere empty and away from the traffic. Caution: Don’t change your flat tyre on the highway! Get help from roadside assistance provided by the highway company.
2. Turn on your hazard lights.
3. Leave your gear at Park (P). Pull your handbrake.
4. Grab the jack, tools and spare tyre from your boot.
5. If you have more than one tyre that is punctured, your only option is to tow it to the nearest workshop.
*It is highly recommended that you check your owner’s manual to ensure a safe process of changing your flat tyre.
**Not all spare tyres operate the same way. Some newer car models come with a space saver wheels.
Steps to change your flat tyre:
1. Loosen the lug nuts slightly Loosen the lug nuts using the lug wrench in an anti-clockwise direction.
TIP: If the nuts are too tight, use your foot/ your body weight to push the wrench. Do not remove the lug nuts completely at this time.
2. Place the jack under your car Check your owner’s manual for the recommended spot to place the jack to safely lift your car and avoid damages. 
3. Raise your car Caution: Never put any part of your body underneath the car during/ after jacking up your car to prevent injuries. 
4. Unscrew the lug nuts and remove the flat tyre You can now unscrew the lug nuts completely. Make sure you place them somewhere safe so that you don’t lose them. Remove the flat tyre by pulling it towards you and set it on its side.
5. Put on the spare tyre Put on the spare tyre and the lug nuts. With your hand, tighten the lug nuts clockwise as tightly as possible and then tighten with the wrench to secure the spare tyre.
6. Lower your car Bring your car to the ground and remove the jack. Use the wrench to tighten the lug nuts as much as possible.
7. Keep all your tools and the flat tyre. Drive to the nearest tyre shop. You should get the flat tyre fixed as soon as you can because the spare is just for temporary use only.
Make sure to always check your spare tyre. You don’t want your spare tyre to be deflated when you need it most. Be safe on the road!
