# Analysis of Source Content The product information contains a discrepancy: the main description states “up to 23″” whilst the features mention “up to 24″”. The specifications list “13” to 23″” for rim diameter. I’ll use the specification value (23″) as the authoritative source. The source contains a full specifications section and a contents section with actual data, which I must preserve at the end. # Product Description The Draper Expert TC100 is a semi-automatic tyre changer designed for removing and replacing tyres on wheels up to 23″, making it ideal for workshops, garages and mobile tyre fitting services. This professional-grade machine combines a fully motorised turntable with pneumatically operated clamping jaws and a powerful pneumatic bead breaker to handle conventional tyres efficiently. The self-centring four-jaw chuck is controlled by two clamping cylinders, ensuring wheel rims are correctly positioned and secured during operation. The mounting head features plastic protectors specifically designed to treat alloy rims gently, whilst the bead breaker incorporates a large anti-skid rubber pad that preserves both tyres and rims during the changing process. Practical design features enhance usability in compact workshop environments. The mounting arm swings to the side, allowing the machine to be installed directly against a wall where space is limited. Operating from a standard 13amp 3-pin plug, the TC100 requires a pneumatic supply of 90-115psi (6-8BAR) to power its clamping and bead breaking functions. The machine is supplied complete with essential accessories including a tyre lever, filter regulator lubricator, alloy rim protectors, head tongue protectors, and an inflation gun with air hose.
