Maintenance
Air Pressure (Inflation Pressure)
STL recommends checking tyre pressure at least once every fortnight (a tyre that has not been used for at least 3 hours).
- Checking inflation pressure of the tyre after a long use is best avoided.
- Always use the pressure recommended by the tyre manufacturer.
- STL recommends use of dry air (clear of moisture, dust, etc.
- After checking the tyre pressures, do not forget the replace the valve cap, which in addition to protecting valve core against dust, also acts as a secondary air seal.
Causes
Mismatch or improper inflation pressure of the front and rear tyres can have an effect on the handling of a bicycle.
Troubleshooting
Check the pressure of the tyres with calibrated gauge and if any irregularity is observed in the inflation pressure, adjust the pressure to recommended pressure, given manufactures.
Correct Placement
- Tyre(s) of rib pattern are recommended to be mounted on the front tyre and tyre of lug pattern should be on rear wheel.
- Tyres having semi lug/semi rib may be used in front/rear wheel both.
Mounting
- The tyre and the wheel must be thoroughly inspected by the fitter during mounting(inside & outside).
- Specifications provided by tyre manufacturer must be complied with.
- The rim must be clean and in good conditions (free of rust and sharp edges).
- Tyre and the rim type match.
- The valve of tube should have dust cap to avoid any damage in usage.
- Better to have a suitable lubricant, lubricate all the bead seat area of the rim and also the bead of the tyre, on both sides.
- Fit the tyre as per the rolling direction, which is indicated by an arrow on its sidewall.
- Use suitable levers perform bead to rim mounting, and finishing at the location just ahead of the valve.
- Mounting of tyre, Inflate until the bead are well seated on the rim & inflate without the core. Continue inflation up till defined air pressure mentioned on tyre for a proper bead seating.
- Replace the valve core, if any leak observed in valve, inflate to the recommended pressure and screw the valve cap.
Notice
- For safety reasons, for usage of new tyre, we recommended to use a new inner tube.
- Rim band/Rim tape must be used to avoid spokes to damage inner tubes.
- Inflate the tube slightly during fitment of tyre on rim.
Do's
Use always lubricant vegetable, to lubricate bead.
Dont's
Do not mount tyre with lubricants which contain minimal/petroleum based products. Do not mount tyre manually with improper tools.
De-Mounting
- The tyre and the rim must be thoroughly inspected by the fitter (inside & outside).
- Specifications provided by tyre manufacturer must be complied with.
- The rim must be clean and in good conditions (free of rust/burs/sharp edges).
Do's
Maintain the fitment tools in good working condition & only use clean vegetable based lubricants.
Dont's
- Do not de-mount a tyre without application of lubricant on rim.
- Do not damage the bead by using poorly maintained tools & osther methods.
