Trailer King RST ST 225/75R15 117/112M E (10 Ply) tire

Trailer Tire for Highway Use

The Trailer King RST is a highway terrain, all-season tire built for special trailer service. Its ribbed tread design and rubber compound improve steering response and towing stability on dry, wet and winter roads. Optimised grooves clear water and slush from the footprint to resist hydroplaning. This model is not intended for light-truck fitment.

Thermals, Noise and Power Draw

The silica-reinforced compound and strengthened internal structure maintain consistent rolling resistance across temperature ranges. An 8/32 tread depth and wear-resistant compound promote even wear, reducing vibration and road noise during normal highway cruising. The 10-ply load-range-E construction supports a 117/112 load index at speeds up to 81 mph without excessive heat buildup.

Sustained Load Behaviour

Under continuous loaded operation the reinforced carcass resists deformation, preserving the contact patch for stable handling. The optimised tread pattern distributes stress evenly to prevent irregular wear formations over long distances. All-season compound flexibility retains traction through seasonal temperature swings while the 28.3-inch overall diameter maintains consistent revolutions per mile on 15-inch rims.
