[ "Know about the rolling resistance of your car tyresCombined forces acting against the forward movement of a vehicle isknown as rolling resistance. The major part is played by the inertia, gravity,vehicle weight, friction between road and tyre surface as well as the air drag.When you drive a car or ride a bike, it is the rolling resistance that makesyou slow down or brings you to halt. The weight of the vehicle, gravity andinertia, the amount of friction between the tyres and the road surface, and airdrag all play a part.Rolling resistance is caused by tyre deformation and is linked with: The     forces acting on the tyre Loss     of energy due to heatThe energy dissipated as heatThe shape of the;Hankook Tyres London;changes when thetyre makes contact with the road. The tyre gets compressed. The tyre casing andthe rubber tube parts get heated up as a result of this compression. The treadon the exterior part of the tyre heats up when it makes contact with the road.As compared to smooth tyres, more rolling resistance is present in a tyrehaving knobbly tread. This is due to the fact that more rubber gets compressedand there is more heat.The tyre is similar to a rubber band or spring. As the tyres getcompressed, it stores some amount of energy. When the vehicle returns to thegarage, not much of this energy is left as this has been used in heating thetyre. Hysteresis is the energy loss as a result of heating. This indicates thata very less amount of energy would be left that is not enough to make thevehicle move faster.This heat is noticed if your tyre temperature can be felt when you drivefast. More heat is produced if the tyres of your car are not inflated hard.The rolling resistance force is not changed at high speeds. However,more power is used by the car driver to drive against this resistance as moreheat is produced at high speed.Forces on the tyres front part are greaterA huge amount of force is needed to get the tyre squeezed as the tyresfront portion makes contact with the road. Thus, a backward force is caused onthe wheel by this. A force pushes on the wheel in a forwarding direction whenthe tyre returns off the road. But, this force in forwarding direction is notthat great. This is due to the tyres internal friction.If a tyre could be designed in such a way that the internal friction isabsent in it and it doesnt heat up, the front force in the tyre making contactwith the ground would be the same as the back-section force. This wouldindicate the absence of rolling resistance in which it can be assumed that noenergy loss has taken place as a result of compression.Factors affecting rolling resistanceThe weight of the vehicle, tyre design, cornering, and surface of theroad and tyre pressure determines the Rolling resistance. Weight:;More     weight indicates gravitational downward force on the road. Rolling resistance elevates as more compression in the tyres occurs. Carrying more load increases the rolling resistance. Cornering;     The drivers slow down while taking corners as more downward force results     from cornering, which elevates the rolling resistance. Moreover, as the     rubber of the;Tyres London;gets twisted sideways while     cornering, the rolling resistance increases as more heat as well as     friction is produced. Road     terrain:;Less rolling resistance is offered by many terrains. Rough roads offer more rolling resistance. Soft dirt ground and grass are better Rolling resistance is increased on deformed surfaces. ; Design     of tyres; Less amount of rolling resistance is resulted from picking construction and materials that dont get heated up.     Manufacturing the tubes with special latex rubber is an effective way.     Racing tyres are pumped hard, narrow and smooth. For minimizing the heat loss resulted from deformation, the casing is designed. With fewer tyres being compressed, very little heat is produced. Hence, more energy is present for high speed. You can have several options to consider." ]
