Find Punctures in Your Tires

Whether you cycle to work and want to keep your tires in tip-top condition or you want to check why the warning light keeps flashing up on your car's dash, a soap bar could be everything you need to find punctures in your tires. All you need to do is lather up a soap bar to create a bowl of soapy water, and dip the tire into the bowl. If there's a hole or leak, you should see bubbles start to form.

Of course, the soap won't fix the tire for you, but it's still a budget-friendly way to help you know for certain whether you do have a puncture or not.
