Overview: The Hankook e3 Max TL21 is a commercial-grade, highway terrain, all-season tire crafted for use on trailer axles only. It is not suitable for light trucks due to its specialized construction, which is optimized for trailer applications. The tire offers excellent performance in various weather conditions while supporting the heavy loads typical of commercial trailers.
All-Weather Traction: With a ribbed tread pattern and durable all-season compound, the e3 Max TL21 provides consistent traction in dry, wet, and even winter conditions. Its flexibility is maintained in colder temperatures, and the optimized siping pattern enhances grip. The tires circumferential grooves help to disperse water and slush, reducing the risk of hydroplaning and improving safety in challenging weather.
Fuel Efficiency and Tread Life: The symmetric tread design evenly distributes pressure, reducing rolling resistance and the energy required to maintain motion. This leads to lower fuel consumption and decreased CO2 emissions, contributing to a more environmentally friendly and fuel-efficient performance. The combination of reduced rolling resistance and a durable compound also slows tread wear, providing longer-lasting tread life and ensuring even wear patterns throughout the tires' lifespan.

R22 Applications:
R22 (Chlorodifluoromethane) has been one of the most widely used refrigerants in heating and cooling systems for several decades. Although its usage has been restricted under the Montreal Protocol due to its environmental impact, R22 is still used in several industrial applications in countries where it is yet to be phased out. Here are the primary uses of R22:
Air Conditioning Systems: Traditionally used in residential, commercial, and industrial air conditioning units, R22 provides effective cooling. However, in developed countries, it has been phased out for environmental reasons.
Propellant: Used as a propellant in various aerosol applications and a versatile intermediate in organofluorine chemistry.
Industrial Applications: R22 is employed in industrial refrigeration systems for cooling large-scale processes and materials, though alternative refrigerants are now preferred.
Environmental Note: Due to its relatively high GWP and ODP, R22 has been phased out in developed nations since 2020, with a complete phase-out planned in developing nations by 2030. Alternatives like R410A and R134A are now widely recommended for new installations.
