TYRE SAFETY

GETTING THE RIGHT TYRE

Proper selection of tyres for the vehicle is very important to ensure optimum and safe operation. Some of the critical factors to be considered for correct tyre selection are:

  1. Vehicle type & use (passenger or goods)
  2. Load carried and type of load (Load Index/PR)
  3. Speed and sustained operations (Speed Symbol)
  4. Type /Rim combination (Tyre Size and Rim Profile)
  5. Operating conditions (Type of Roads/Terrain)
  6. Tyre pattern design requirements based on the application

TYRE MOUNTING AND DISMOUNTING

MOUNTING

  • Ensure that the rim is correct for the tyre size to be fitted.
  • Clean the wheel thoroughly to remove all contamination.
  • Ensure that the wheel is not cracked, deformed, damaged or bent.
  • Lubricate the tyre beads with an approved tyre lubricant.
  • With the tyre on the rim, start the inflation, making sure that tyre beads are seated correctly on the rim seat.
  • For safety reasons always use a new tube when fitting new tube type tyres.
  • Tubeless tyres must be fitted on air tight rims.

DISMOUNTING

  • Before starting to remove, ensure that the tyre is completely deflated.
  • Ensure that there is no danger of the tyre bursting due to damage, exposed plies, etc.

TYRE SAFETY WARNING

  • Tyre mounting / demounting and changing can be dangerous and should be done by trained personnel using proper tools and procedures.
  • Never mount or use damaged tyres/ rims.
  • Explosion of tyre rim assembly can occur due to improper mounting, mis-application, improper inflation or overloading leading, to serious injuries or death.
  • Never use inflammable substance in a tyre.
  • Never use a tyre worn beyond the TWI.
  • Observe posted speed limits Avoid fast starts, stops and turns.
  • Avoid potholes and objects on the road. Do not run over curbs and hit the tyre against side railings, dividers and curbs. Do not spin the wheels.
  • It is dangerous to neglect tyre damage. Do not overload tyres.

LOAD SPEED INDEX

LOAD SPEED INDEX.png


LOAD INDEX

A numerical code or numerical number associated with the maximum load a tyre can carry at the speed indicated by its speed symbol under the specified service conditions.

SPEED SYMBOL

Speed symbol is an alphabet that indicates the maximum speed at which a tyre can carry a load corresponding to its load index.

TYRE VISUAL INSPECTION

Pneumatic tyres having the following conditions are considered unsafe for use:

  • Tyre body fabric/belts/plies exposed by wear, by injury, road hazards, damage, abrasions or scoring, etc.
  • Tyres having incipient failures by local deformation, bulging, swelling etc.
  • Pneumatic tyre which has been patched or repaired improperly or use of gaiter other than proper repair and vulcanization.
  • Tyre worn beyond tread wear indicator, having signs of severe, uneven, mis-alignment, patchy wear.
  • Broken cord or flat due to puncture, damage in bead area, damaged inner liner of tubeless tyre.
