TYRE CARE TIPS
Tyre inflation tips
Proper Tyre Matching improves the overall performance of tyre & vehicle:
Ensure all tyres fitted on a vehicle are of the same size
Match correct rim for tyre
Fit same construction tyres in one vehicle. Avoid mixing of Radial & Bias.
Avoid mixing of patterns on the same axle
Preferably, fit same manufacturer tyres
Avoid mixing of different wear tyres on same axle
Do not mix uneven tyres with new one
Check the exterior of the tyre for any damage / air pressure / abnormal wear.
Remove stones or nails which are entrapped in the tread of the tyre.
If any abnormal / uneven wear found, consult with tyre specialist or vehicle mechanic.
If the damages exposing the ply cord and/or steel belt are visible, consult with a tyre specialist or see a tyre repairing centre.
If pressure check indicates tyre has lost the pressure, look for the signs of penetration, valve leakage or wheel/rim damage & consult the tyre
Wheel Alignment consists of adjusting the angles of the wheels so that they are perpendicular to the ground and parallel to each other. The purpose of these adjustments is maximum tyre life and a vehicle that tracks straight and true when driving along a straight and level road.
Increased tyre life
Less wear & tear of suspension joints
Excellent steering control & driving comfort.
No “side dragging” or pulling
Spot braking without drag
Increased fuel efficiency
Wheel balancing allows the tyres and wheels to spin without causing any vibrations. This is accomplished by checking for any heavy spots on the wheel-tyre combination and compensating for it by placing a measured lead weight on the opposite site of the wheel from where the heavy spot is.
Vibration in the steering wheel at certain highway speeds
Vibration in the seat or floorboard at certain highway speeds
Scalloped or cupped wear pattern on the tyres
Demounting means removal of the old tyres from the rims and mounting means putting the tyre on the rim for the vehicle.
Apply the tyre and tube lubricant – tyre, tube & flap should be lubricated with powder without leaving lump inside the tyre.
Fit the tube & flap inside the tyre and inflate 2 to 5 psi & set the tube & flap properly.
Fix the tyre to rim properly & adjust the valve core in the rim slot properly, uniformly.
Fit the rim flange & lock ring & insure proper fitment with help of rim centring line on the tyre.
Inflate the tyre to the recommended pressure & deflate. Again re-inflate the tyre to the recommended pressure.
Fit the prepared tyre to the wheel hub.
Fixing the wheel nuts to the wheel bolts should be in criss-cross method
Follow the reverse process of mounting to demount the tyre from rim.
Proper load distribution ensures the right traction & prevent the driving wheel to slip, resulting in proper & even tyre tread wear.
