Fitting Tubular Clincher Tyres
- Make sure that the rim is the right size, according to the tire label. Do not use rim tape. Do not use any tools.
- Complete deflation of the tyre is necessary before installation.
- Place the wheel on a firm surface (valve opening on top). Slide the tyre valve through valve hole in the rim. Starting from the valve, stretch the tyre evenly on both sides (fig. 1a) and lay half of the bottom rubber profile into the rim well (fig. 1b) step by step, all around (fig. 1c). If the tubular clincher tire is hard to put on towards the end (fig. 1d), do not use excessive force but start mounting again from the valve and stretch the tyre harder.
- Inflate the tyre slightly (fig. 2) to around 1 bar (15 p.s.i.)
- Lift the tyre from the rim well with fingers (fig. 3a) and fit the groove of the rubber bead profile into the rim lip (fig. 3b) all around one side of the rim.
- If you cannot lift the tyre, deflate it slightly.fig3.gif
- Push with thumbs on the other side of the rubber bead profile (fig. 4a) and fit the groove into the rim lip all around again (fig. 4b).
- Inflate the tyre to 5 bars (75 p.s.i.) [MTB to 2 bars (30 p.s.i.)] and check for fit on both sides of the rim. Refit if necessary (fig. 5).
- Inflate the tyre to the recommended pressure as indicated on the tyre label.
