Mastertrack UN-203


  • All weather traction
  • Enhanced controllability
  • Towing durability


The Mastertrack UN-203 is a highway terrain, all season tire manufactured for special trailers. This model is not meant to be used on light truck vehicles, it is for trailer use only.

The all weather traction is thanks to the special tread design and the tire compound. They work together to ensure excellent dry, wet and winter weather road gripping ability. While trailer tires do not need as good of a traction as the towing vehicle's tires do, this tire still provide great driving safety in all weather conditions. The compound maintains its flexibility, while the tread design firmly grips the road surface all year round. The wide circumferential grooves prevent hydroplaning by eliminating water and slush from below the tire's footprint and promote a safer drive.

The model is easily controlled by the towing vehicle. The tread design's ribbed pattern increases the road grip and with it the tire's controllability. The ribbed design boosts the steering responsiveness and the driving stability. It stabilizes and secures the tire's structure against the driving pressure affecting it during the drive. It also improves the response time and accuracy to the towing vehicle's instructions. The better controllability ensures better responsiveness to the towing vehicle and makes the drive safer.

The UN-203 guarantees excellent safety. The model's internal radial construction improves its durability. It prevents deformation under the driving pressure affecting the tire, and it guarantees a safer driving experience. The maintained optimal shape ensures a secure drive and prevents the tire from being damaged by the driving pressure affecting it.

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.
