TR4: It is a common valve size that is usually used for light and medium duty vehicles such as domestic vehicles, small trucks and motorcycles.
TR6: Valves are usually used in some light commercial vehicles and tractors.
TR13: is a small valve size usually used in equipment such as wheelbarrows, small tractors and lawn mowers.
TR15: A larger valve size, usually used for some construction vehicles and tractor tires.
TR218A: Valve size usually used for agricultural vehicles and some large tractors.
VS-20: is a flange valve size usually used in premium cars and high performance vehicles to improve aerodynamics.
HP2: is a high-pressure valve specification for special applications that require high pressure air, such as trucks, buses and large commercial vehicles.
V3.20.6: This is a flanged valve tip specification that is commonly used in some high-end and luxury vehicles to improve appearance and aerodynamics.
These are some common valve sizes and different types of vehicles and tires may require different valve sizes. When purchasing a valve or replacing a tire, it is best to consult your vehicle’s manual or a professional technician to ensure that the correct valve specification is selected.
TR43 is one of the international specifications for tire valves, which was developed by the European Tyre and Rim Technical Organisation (ETRTO), an organization specializing in technical standards related to tires, rims, and valves, founded in 1963 and headquartered in Belgium.
The specifications developed by ETRTO are mainly applied to tires and rims as well as their related components, including tire valves. TR43 is the technical standard for tire valves developed by ETRTO, which is used to define the size, shape, material and performance requirements of tire valves.
The ETRTO standards development process usually includes the following steps:
Committee Establishment: ETRTO establishes a corresponding committee or working group, composed of industry experts, to develop relevant standards.
Draft formulation: The committee drafts the relevant standard based on the results of discussion and research.
Public Consultation: After the draft is completed, ETRTO publishes it publicly to solicit comments and suggestions from the industry and relevant stakeholders.
Review and Revision: ETRTO reviews and revises the draft based on the feedback received to ensure the accuracy and applicability of the standard.
Voting: After several rounds of review and modification, the final draft standard will be submitted to ETRTO members for voting.
Publication and Implementation: If the draft standard is adopted with the support of enough members, ETRTO will officially publish the standard and promote its adoption and implementation by member countries.
International specifications for tire valves, such as TR43, are developed by ETRTO to ensure consistency and interchangeability of tire valves and promote safety and performance of tires and rims.
The main international standards for tire valves include the following two:
ISO 7638-1: This standard specifies dimensional and performance requirements for pneumatic connectors, including valve nipples and connectors, for use on commercial vehicles and trailers. It covers a range of commercial vehicles such as trucks and trailers. The standard ensures the interchangeability of pneumatic connectors and the reliability of the connection to ensure proper pneumatic operation in commercial vehicles.
ISO 10473: This standard specifies requirements for the interchangeability of tire valves and air pressure sensors for cars and light commercial vehicles. Part ISO 10473-1 covers general performance requirements, while part ISO 10473-2 covers air pressure sensors with tire pressure monitoring systems (TPMS).
The key to distinguishing between the two standards is the scope of application and the type of vehicle. ISO 7638-1 applies to pneumatic connectors for commercial vehicles and trailers, mainly large commercial vehicles such as trucks and trailers. ISO 10473, on the other hand, applies to cars and light commercial vehicles, and is aimed at smaller vehicles such as sedans and minivans.
For consumers, it is important to pay attention to the type of vehicle and its use when purchasing vehicle valves, and choose the valve specification that matches their vehicle. Generally speaking, vehicle manufacturers will select the appropriate valve tips according to the requirements specified in the standards. If it is necessary to replace the valve tips or carry out repairs, it is recommended to consult a professional automotive service technician or purchase the appropriate original parts to ensure compliance with the standard requirements and to ensure the safety and performance of the vehicle.
There are some differences between bicycle tire valves and automobile tire valves in terms of design and use, mainly in the following areas:
Size and type: Bicycle tire valves are usually shorter and thinner, and generally come in two types: regular models use blue or black generic valves, while high-pressure road bikes (road bikes) usually use thinner Presta valves. Car tire valves, on the other hand, are longer and are usually generic car valves.
Pressure Requirements: Bicycle tire pressures are relatively low, typically between 30-100 psi (pounds-force/square inch), while automotive tire pressures are usually above 30-40 psi.
Applicable Vehicles: Bicycle tire valves are suitable for small vehicles such as bicycles and motorcycles, while automotive tire valves are suitable for large vehicles such as cars and trucks.
Tools: Presta valves usually require a special spool tool to inflate, while regular valves can be inflated with a regular air cylinder. Car tire valves, on the other hand, usually do not require the use of additional tools.
TPMS Function: Some modern cars are equipped with Tire Pressure Monitoring Systems (TPMS), which require a valve with a sensor to monitor tire pressure. However, bicycles are generally not equipped with such systems.
Despite these differences between bicycle and automobile tire valves, they both serve the same basic function of allowing air to enter the tire and adjusting the tire pressure to ensure optimal performance and stability while the vehicle is on the road.
