Attention! Due to the size of the tires, Packages might be SEPARATED in the courier facility and not be DELIVERED on the SAME DAY, even though we do ship them together. Tracking information can be checked by logging on to the courier website with the master tracking number you will receive via email. For example, you can receive 3 tires in one day and the 4th one the next day or the day after, or one tire in one day and the second one day after. We understand that this is a big inconvenience for our buyers, however, this is ABSOLUTELY out of our control.


Westlake GTX1


  • Fuel-efficient performance
  • Enhanced controllability
  • All weather traction
  • Upgraded load durability


The Westlake GTX1 is a highway terrain, all season tire made for commercial vehicles. This model is made to be mounted on trailer positions.

Excellent all season performance is promoted with this tread design and all season compound. This model promotes safe year-round traction. In this manner, the ribbed tread pattern closely follows the road surface in dry, wet, and winter conditions. On the other hand, the all season compound keeps the rubber flexible in summer and winter temperatures. At the same time, wide zigzag grooves prevent hydroplaning by dispersing water and slush from the footprint.

The ribbed tread design and the rubber compound keep consistent road contact, which upgrades controllability. This road contact enhances steering responsiveness and driving stability. In other words, it increases the steering response time and accuracy to the driver's commands, while the structure is secured against driving pressure. The outer shoulder ribs strongly grip the road surface, which boosts cornering and maneuvering. These elements guarantee the tire's safe performance on various highway surfaces.

The model offers a fuel-efficient drive. The fuel-saving compound and the optimal tread design upgrade traction, lowering the rolling resistance. The pressure that affects the tire regulates the vehicle's needed fuel intake levels. As a result, the tire decreases the vehicle's fuel consumption and CO2 emissions. This leads to a fuel-conscious and environmentally friendly driving experience.

The Westlake GTX1 boosts load and driving durability. The strengthened internal structure and durable rubber compound keep the ideal tire shape under load and driving pressure. As the tire does not deform under pressure, it is able to carry and withstand heavy loads. This upgrades the overall load capacity and handling power. As a result, it improves the heavy-duty performance and makes this model an excellent choice for commercial vehicles.

Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
