What is Tyre Rolling Resistance? How LRR Tyres reduces the Fuel consumption?

Tyre Rolling Resistance

One of the major aims for a chauffeur is to save petroleum of automobile. However, due to the resistance of tyre up to 60% of the fuel is wasted.

If you are concerned about fuel consumption or planning to buy a new car tyre then you must read this article.

What is Tyre rolling resistance (TRR)?

Tyre rolling resistance is the energy that is spent by your car to conserve speed and steadiness on the surface of the road. When you accelerate the automotive, you are literally transferring power to the engine that is present in the vehicle.

Only if this occurs, your car starts to move. Hysteresis is one such factor that is triggered here. This is a noteworthy reason why your diesel is wasted.

There are other factors like aerodynamic drag and road friction that contributes to tyre rolling. But the percentage of impact these triggers would be less compared to Hysteresis.

Moreover, a driver cannot have complete control over those hence a strategy to lower Hysteresis should be adopted.

What affects tyre rolling resistance?

Though there are so many things that affect tyre rolling friction we have picked the most important ones here.

  • The resistance of Aerodynamics – This is nothing but the air in the atmosphere. When there is higher aerodynamics the tyre resistance increases too. It would be hiked to 15%.
  • Weight – Weight has a great impact for sure. If the tyre is less in pounds then there will be less force created. It is vice versa for heavyweight tyres.
  • Speed – Maintaining a speed anywhere between 10 and 55 mph can help to get minor resistance. In this rate, the resistance goes up to 1 lb only. However, when driving in exceeding speeds it contributes to elevated resistance. So, we recommend you to sustain lower speeds to curtail tyre rolling drag and to save fuel.
  • Improper maintenance – Yes! You read it right. When the automobile is not handled properly it would cause a tear in the product. Due to damage caused by the item, it increases the loss of Hysteresis.
  • The inappropriate pressure in tyres – Fill your tyres with proper air pressure at any cost. Do not use it in flat tyres. When the pressure is very low it increases rolling resistance up to 35%.
  • Skid angle – While a car takes a turn, brakes or quickly changes the direction of motion it increases the rolling resistance. These things cannot be inhibited while driving a vehicle by anyone. It is just that a way out should be made in order to keep the wheels in apt angle.

It is a known fact that these issues are minute and in fact not found when the car or any motor vehicle is fitted with Low rolling resistance tyres.

Is it true that declining rolling resistance has an impact on tyre grip?

There is a myth that when the tyre rolling resistance is pruned it would have a major strike on hold on the surface. But this is not true thanks to modern technology.

Not only the grip is well maintained but also the durability of the wheel is increased.

How to avoid Tyre rolling resistance?

It is not possible for you to completely prevent tyre rolling resistance incident however with engineering techniques it can be minimized.

When you drive your vehicle it is going to have proximity to road thus causing resistance. So the tyres need to be re-designed to meet the need of people.

Tyres can be incorporated with tread compounds that are created specifically to have resistance against heat. So, loss of energy becomes low and it reflects on fuel economy. This type of tyre is termed as low rolling resistance tyres.

How much fuel can be saved with the help of Low rolling resistance tyres (LRR)?

When you use conventional ones, around 25% of the gas is wasted. The resistance of tyre contributes about 80% of energy on tyres.

In case of excessive pressure or temperature, your engine eats up more power to travel to the same distance. These scenarios can be eliminated just by infusing LRR model.

The practice of these provides a reduction in gasoline consumption up to 0.50 litres for a hundred kilometres. We know that this sum does not impress you.

So, we would calculate it for the lifetime of the tyre for you to get a bigger picture. You would be saving around $600 at your expense in the lifespan of the product. The efficiency of fuel would be increased from 1 to 5 mpg.

What are the advantages of using LRR tyres?

Till now, we let you know that using LRR instead of conventional tyres help you to save oil. However, there are few other benefits of using LRR.

  • Saving operational fluids – There are many types of liquid in your conveyance like power steering fluid, oil, washer fluid and brake fluids. The new technology wheels can also aid in diminishing the absorption of these operational fluids.
  • Fewer emission of CO2 – Discharge of carbon dioxide from automobiles is a serious concern in the modern world. Just by replacing your truck or car with LRR tyres you can be in command of these emissions to a greater extent. You can go green to protect the environment.

What are the disadvantages of using LLR tyre?

It might not be considered as a disadvantage but a compromise that individuals had to do.

  • Reducing tread depth – The tread depth is shrunk in order to boost the rolling friction. This is where the drawback occurs. This cutback would also drop off the tyre wear off time. Here, the tyre has to be repaired or replaced.
  • No solution to tyre wear issue – Till date, there is no proper resolution for this issue. Fortunately, researches are conducted in order to find a path to increase wear performance in LLR tyres.

Is LRR expensive compared to conventional tyres?

The amount that you invest to get the former one might be huge compared to the latter. But, the benefits that you yield would be more and it is worth spending on.

The next generation tyres are LRR so it is better you opt one too. Moreover, there is a remarkable rise in fuel price too hence this is the right time for you to choose a method to save it.
