The bottom of one tire is bulged out more so than the others.The suspension may feel softer than usual.As you’d expect, a flat tyre is the most common symptom of a tyre leak.If the valve stem is leaking, a new one is installed. The technician will remove the tyre from the rim, grind the surface clean, then liberally apply tyre sealant on the rim before reinstalling the tyre. If the leak is from the bead area, it’s likely due to corrosion.

If there’s a puncture through the tyre and its lining, the tyre needs to be removed from the rim and properly fixed. If your tyre keeps losing air or going flat, you’ll need a tyre repair.Ī tyre repair restores the tyre’s integrity to hold air. It could be a nail that punctures through the tread, cracking in the sidewall, the tyre valve stem doesn’t seal, or corrosion on the tyre bead. If any of these parts are compromised, your tyre can go flat. The tyre bead is thick and stiff, sealing your tyres onto your wheels. The tyre valve stem allows compressed air to enter, the seals to prevent it from escaping. The inner liner is like the tyre tube on your bicycle, keeping pressurised air on the inside. Your tyres are made up of several layers including a durable outer tread layer and an inner liner.
