How Rolling Resistance Coefficients Impact Tire

In order to choose the right industrial application tire, it is important to know about solid tires and their coefficients of rolling friction. Rolling resistance is a major factor that affects energy efficiency and vehicle performance especially in tough conditions. In this blog post we will discuss rolling friction and its causes as well as different types of solid tires with their respective values for coefficient of rolling friction.

What is Rolling Resistance?

Rolling resistance can be defined as energy lost by a tyre when it rolls over a surface. The main reason for this loss is deformation of the tire during contact with ground. It is an essential parameter because it affects fuel efficiency directly thus influencing operational costs. Low rolling resistance means less power needed to move the vehicle which translates into better mileage per gallon and reduced emissions.

Factors Affecting Rolling Resistance

There are many factors that affect rolling resistance in solid tyres including:

  1. Tire Composition: Materials used in making up the tyre such as rubber compounds or fillers greatly determine its ability to roll freely without much effort thereby affecting its co-efficient value for rolling on different surfaces.
  2. Tread Design: Pattern along with depth distribution across section area also known as tread design influences contact patch shape between road surface where wheel touches pavement leading to changes in deformability therefore influencing RRCs.
  3. Tire Pressure: Proper inflation should be observed since underinflated tires tend to have higher degrees of deformations hence increased values for coefficients due to this effect alone having more impact than any other factor mentioned above.
  4. Temperature: Operating temperatures affect elasticity modulus which subsequently alters dynamic characteristics like viscoelasticity thereby changing total energy loss through hysteresis mechanism responsible for RRCs at varying speeds but generally expected trend would be higher temperature resulting into larger resistance forces against motion produced by tyre rolling on any given ground.
  5. Surface Type: Different types of surfaces offer different levels of rolling resistance. For instance smooth surface will have lower coefficient than rough or uneven one since the former has less contact area between tire and pavement thus reducing energy dissipation during deformation process along its path length.

Effect on Energy Efficiency

Energy can be saved significantly by understanding and choosing tires having lower rolling resistance coefficients. This implies that for electric powered industrial trucks like forklifts, less frictional force on the ground will allow the battery to last longer between charges while in use. In internal combustion engine vehicles, it also cuts down fuel consumption lowering operation cost.

Case Study: Forklift Application

Suppose a warehouse has many electric forklifts which operate continuously throughout the day. The business can save about 66% of energy used in moving these machines by changing from normal solid tire (0.03 RRC) to airless radial tire (0.01 RRC). Therefore, this decrease is not only going to reduce power bills but also increase overall efficiency and productivity of operations within warehouses.

Future Trends and Innovations

Tire makers are still trying hard with different materials and patterns in order to achieve even less rolling resistance than before. Nanotechnology breakthroughs together with advances in material science may lead into creation of compounds that have similar strength as solids but with much lower RR properties. Furthermore, smart tires which monitor their own temperature and pressure could be integrated so that they always work under best conditions thereby reducing RR.


In industry applications where minimum energy consumption is desired, it’s important to choose appropriate solid tyres based on their rolling resistance coefficients. Businesses should know what affects rolling resistance and compare various types of tyres’ performance against each other so as to make informed decisions that positively impact on profitability we expect more efficient technologies will be invented as time goes by thus making industrial vehicles even more effective.

Therefore, when selecting any type of solid tire one must understand all aspects related to its coefficient of RR since they differ greatly among them whether standard or cushion or PU or AR ones because every kind offers specific advantages depending on operational requirements this means investing right kinds not only enhances efficiency but also contributes towards sustainability through cost effectiveness in operations.
