How to read the energy efficiency label for tires?
The energy efficiency label for tires contains six different levels, ranging from excellent to very poor, and it consists of two sections:
The left section is dedicated to energy efficiency-related information, such as the amount of fuel saved based on the rolling resistance rating of the specified tire. If the black arrow is pointing at “Excellent” (green category), it means that the tire is classified as one of the most fuel-efficient products in the market, while if the arrow is pointing at “Very poor” (red category), this means that the tire is classified as one of the least fuel-efficient products in the market
The right section is dedicated to safety-related information, mainly the wet grip rating of the specified tire, reflecting the tire’s resistance to slipping on wet surfaces. If the black arrow is pointing at “Excellent” (green category), it means that the tire is classified as one of the safest products in the market when driving on wet surfaces, while if the arrow is pointing at “Very poor” (red category), this means that the tire is classified as one of the most unsafe products when driving on wet surfaces..
What are the differences between the different Levels? How much fuel can be saved under each of these levels?
In terms of energy efficiency, the lower the tire’s resistance to on-road rolling, the better the level of energy efficiency. Hence, having better performance and less fuel consumption (around %1.5- 2.5 fuel savings)
In terms of safety, a higher wet grip rating reduces the distance needed to stop the vehicle when using brakes on wet surfaces. Hence, increasing the safety of the tire when driving under severe weather conditions.
Are there any other efforts made by the Kingdom to reduce the energy consumption in the transport sector?
There are several initiatives related to the transport sector, some of which have been implemented, and others are under development. The most important ones are the Fuel Economy Label for new light-duty vehicles, the Saudi Corporate Average Fuel Economy Standard for new imported light-duty vehicles, the ecosystem of reducing fuel consumption for on-road vehicles, and initiatives targeted at reducing fuel consumption in heavy-duty vehicles.
When do i need to buy new tires for my vehicle? how far or how long can a tire be used before wearing out?
There is no specific way to know when to change a tire, but it depends on several factors: tire design, individual driving habits, climate, and road conditions. One indicator to know when to change a tire is the visible signs on tire wear, also known as “wear bars”. Wear bars look like narrow, smooth rubber strips and are located transversally on the tire tread and will appear when the tire wears out and needs to be replaced. You must replace your tire if 3 or more wear bars appear. Other ways to knowing when to change a tire are visible wires, cords, or fabric showing through the wire tread, deep tread or side cracks or cuts enough for wires or fabric to show, tire cracks or bubbles, or any other non-repairable puncture or damage.
Does maintaining the proper tire pressure reduces fuel consumption? how?
Yes, it does. Maintaining the recommended tire pressure helps prevent tire bulging when in contact with the road, hence decreasing its rolling resistance, and reducing fuel consumption..
When did the implementation of the standard begin? When did the customs and market surveillance begin to ensure compliance with the standard?
The first phase of standard was implemented on the 1st of November 2015. It included imported and locally-manufactured tires.
The Standard does not prohibit selling a certain tire type, but it rather determines the level of energy efficiency required in vehicle tires. Racing tires are usually more efficient, but do not suit all types of vehicles.
Does Purchasing an energy effeicient tire affect vehicle’s speed?
There is no direct relationship between speed and tire type, but the tire’s energy efficiency is rather related to vehicle performance.
Is there a table that shows the tire type and size suitable to each vehicle’s specifications?
The tire size varies depending on the vehicle’s model, as each model requires a specific tire size that you can know by asking the authorized distributor or by referring to the manufacturer’s manual. The tire type varies depending on its use, as there are racing tires, off-road tires, snow tires, and so on.
Apart from saving fuel, what are other advantages of purchasing energy efficient tires?
Energy efficient tires boost up vehicle overall performance, hence reducing load on the engine, because energy efficient tires reduce rolling resistance..
What are other tire-related factors that reduce fuel consumption? Tire size and place of manufacture for example?
There are other factors which contribute greatly to reducing fuel consumption, preserving tire life, and maintaining public safety. Some of which are: maintaining proper tire pressure, balancing the tires regularly, and using tire sizes which are recommended by the vehicle manufacturer.
When purchasing a new vehicle, will it come with energy efficient tires?
Tires that comply with the Energy Efficiency Standard will be installed to light-duty vehicles starting November 2016, and to heavy-duty vehicles starting November 2017.
Are there figures and statistics on fuel consumption in the Kingdom’s transport sector?
According to 2020 data, the transport sector contributes to almost 20% of the Kingdom’s total energy consumption.
