6.7.2 Tyre Types

There are three different types of tyres or inner tubes, and specific points must be observed for the replacement of each
type. The individual types of tyres can be easily distinguished:
• Pneumatic tyres have black valve caps.
• Puncture-protected tyres have red valve caps.
• Puncture-proof tyres have no valves.
There are five chapters about tyre repair and wheel replacement:
• Replacing Drive Wheel (5–Screw Installation)
• 6.7.5 Replacing Drive Wheel (1-Bolt Installation), page 24
• 6.7.6 Replacing Castor Wheel on Double-Sided Fork, page 26
• Replacing Castor Wheels on Single-Sided Fork
• 6.7.7 Replacing Tyres, page 28 deals with tube repair and replacing solid tyres.
Not all chapters are necessarily contained in this manual.
Specific tightening torques for wheels and rim halves are listed in 6.7.3 Specific Tightening Torques, page 22.
