The easiest way to help ensure top mileage and performance from tyres is to give them a simple but frequent inspection for proper inflatsion, treadwear and the presence of any damage
tyre Inflation Pressure
tyres support the overall weight of the vehicle and are the only automobile parts that directly contact the road.
However, it can be said that it is not the tyre, but the air inside which practically supports the load. The inflation pressure determines the tire’s ability to withstand load, and affects a vehicle’s driving performance, handling and passenger comfort etc. The tyre delivers its optimum performance when the inflation pressure is maintained at the level specified in the vehicle owner’s manual. All recommended tyre inflation pressures are specified for cold tyres.
Most importantly, the inflation pressure must be measured by a accurate air pressure gauge.
Vehicle owner’s manuals may specify that for continuous high speed driving, tyres should be inflated to a pressure of 20-30 kPa higher than for normal service conditions in order to increase their rigidity. This will reduce tyre deflection and minimize heat generation which could cause damage (to be discussed in a later chapter).
Mounting and Demounting tyres
The Mounting and demounting a tyre from its rim can be dangerous and should be done by trained personnel using proper tools and procedures.
Mounting a passenger or light truck tyre onto a rim – These are guidelines only and reference should be made to instructions for the specific mounting machine being used
Ensure that the tyre is of a suitable design to fit the rim.
Ensure that the rim is clean and in good condition. Inspect the valve and, if damaged or deteriorated, replace with one of an appropriate type.
Place the wheel on the tyre fitting machine, with the narrow bead ledge uppermost. The wheel should be centered and securely fastened on the tyre fitting machine.
Always use a recommended bead lubricant on both bead seats in order to avoid bead fitting damage.
Fit the bottom bead over the flange first followed by the top bead.
Install the valve core and release the fitting machine clamps.
Place the tyre wheel assembly in a safety cage and inflate the tyre to seat the beads. Do not exceed the maximum inflation pressure specified by the tyre manufacturer for that particular tyre.
Make sure both beads are properly seated by checking the rim line in the bead area of the tyre. If not, completely deflate the assembly, relubricate, reposition the tyre on rim and repeat step (7).
Adjust the inflation pressure and make sure that there is no air leakage.
Install the valve cap.
Demounting a tyre from a rim – These are guidelines only and reference should be made to instructions for the specific mounting machine being used
Always remove the valve core to ensure complete deflation before demounting from rim.
Use the fitting machine to break the tyre beads free from the rim flanges.
Place the tyre/wheel assembly on the tyre fitting machine and be sure that the narrow ledge of the wheel is uppermost.
The wheel should be securely fastened on the tyre fitting machine.
Removing the tyre beads from the rim flanges should be done carefully. If the beads do not readily separate from the rim flanges, lubricate well with bead lubricant.
After the beads are free from the rim flanges, the tyre should be lubricated again. This makes it easier to remove the tyre from the wheel without damage.
