Trailer Tire for Highway Towing

The Trailer Master ST PRO is a highway terrain all season tire built for special trailer service. It carries a load index of 111/106 and load range E with a 10 ply rating. The speed rating N allows operation up to 87 mph on highways.

Sustained Load Behaviour

The reinforced radial structure maintains the optimal tire shape under continuous heavy pressure. This design upgrades overall load capacity and driving durability during extended hauls. The strengthened internal construction also helps prevent trailer swaying when the tire is fully loaded over long distances.

Questions about this item

How much heat does the 205/75R15 tire build up when towing at highway speeds all day?

The N speed rating allows sustained operation up to 87 mph, and the reinforced radial structure maintains shape under load to limit heat buildup during long hauls.

Does the 15-inch rim size match my existing trailer wheels, or do I need new rims?

The tire fits a 15-inch rim; the listing states the rim is not included, so your current wheels must be 15 inches in diameter and compatible with the 205 mm section width.

Will the Load Range E 10-ply rating work alongside my older Load Range D tires on the same axle?

Mixing Load Range E (10-ply) with lower-rated tires on the same axle is not recommended because the 111/106 load index and stiffer sidewall change load sharing and handling balance.
