Pneumatic (air-filled) Jogger Tyres

Basics
A complete wheel consists of 3 main parts.
Rim - this is the main centre part of the wheel. May be made from metal or plastic. The tyre fits onto the rim.
Tyre - the rubber outer has a tread pattern. This part is what touches the ground. The tube sits inside the tyre.
Tube - holds the air and sits inside the tyre. The tube has a nozzle which protrudes through the rim so you can fill tube with air.

Think of the rim as the centre of the wheel, the tyre is the outer most piece and the tube goes inside the tyre and against the rim.

Dust Cap - is the small black plastic screw cap on the nozzle and is ONLY a dust cap. It does not affect performance or loss of air from tube.

Tubes are the only part that holds the air.

Reasons you may have a flat

• Thorn, Bindi, Nail or just something sharp no matter how small
• Over inflation of the tube
• Pram being idle, unused or stored for a long period of time
• Loose nozzle

Reasons you may continue to get flats after changing the tube

• Residue from sharp item is still embedded on the inside of the tyre
• Over inflation of the new tube
• Thorn, Bindi, Nail or something sharp
• Loose nozzle
• Tube incorrectly fitted
• Pinching or catching tube when fitting into tyre and onto rim

Patching a tube
Patching has been proven not to work on pram tubes

What tools you should have available

• Small bicycle tyre lever
• Air pump with gauge
• Valve Key

 How to help avoid flats

• Keep the tubes filled with the correct pressure of air as stated in your user manual
• Be aware that the smallest of grass or weed thorns are capable of puncturing a tube
• Do not over inflate
• Do not leave pram exposed to direct sunlight while it is in the car
