Understanding the Anatomy of a Rim and Tire

A rim, commonly known as a wheel, is the metal structure that supports the tire and connects it to the axle. It plays a vital role in transferring weight and ensuring proper tire rotation. Tires are the rubber components that provide traction, cushion the ride, and protect the rim from damage. A leak can occur either at the rim itself or at the bead, the area where the tire and rim meet.

Identifying the Source of the Leak

Before diving into repairs, it’s essential to identify the source of the leak. Check the tire for any obvious punctures or tears. If no visible damage is present, you can use a simple test to pinpoint the location of the leak. Fill a spray bottle with soapy water and spray it around the bead and the rim’s surface. If you see bubbles forming, you have found the leak.
