USER INFORMATION

TYRE STORAGE:

Tyres should be stored in a cool, dry and dark place away from direct sunlight (Suggested storage temperature: 25°C ± 5°C). Avoid storing tyres in an area which is wet, oily or greasy.

RIMS:

Recommended width of the wheel as specified to be used for optimum performance. However, from the original specified rim width ± 0.5’’ can also be used. ETRTO/JATMA standards can be referred for the correct rim width.

TYRE MOUNTING AND REMOVAL:

Mounting/demounting should be done by trained personnel using a suitable mounting machine. Prior to fitment, inspect the rim and tyres for any external damage. Tyres have to be mounted according to the direction of rotation specified on the sidewall. The rim seating area and tyre beads should be lubricated. Recommended tyre pressure to be followed. Check for the proper seating of the beads and tyre centring with reference to RCR (Rim Centre Ring) after inflation. Balancing of the tyres must be done.

LEFT & RIGHT:

Directional pattern tyres must be used on the correct side. Left or Right and Outer side marking on the sidewall must be followed for best performance.

HAND-CUT TREAD PATTERN:

Groove width between the pattern blocks can be widened if required. However, hand cutting the buttons could alter the performance. Hence a careful decision is to be made based on the terrain conditions.
