Trailer ST PRO 215/75R14

The Trailer Master ST PRO is a highway terrain all season tire built for trailer axles. It carries a 215/75R14 size with a 108/103 load index and speed rating L for up to 75 mph use. The eight ply load range D construction suits single and dual fitments on utility and travel trailers. Rim is not included with the tire purchase.

Reinforced radial structure under load

A strengthened internal structure maintains the optimal tire shape under sustained pressure during heavy duty towing. This preserves load capacity and driving durability over long hauls while helping to prevent trailer sway. The ribbed tread design keeps steady surface contact for consistent steering response and stability mile after mile.

Upgrades from lower ply trailer tires

Replaces lighter load range tires when the trailer carries heavier cargo or travels at highway speeds for extended periods. The jump is worth it when the current tires show sidewall flex or reduced stability under maximum rated loads. Not for light truck fitment or applications needing run flat capability.

Questions about this item

How does the tire handle heat buildup during long highway hauls with the 8-ply Load Range D construction?

The reinforced radial structure maintains optimal shape under pressure, upgrading load capacity and driving durability while helping to avoid trailer swaying during extended use.

What wheel diameter must I already have to mount this 215/75R14 tire?

This tire fits a 14-inch rim; the product includes the tire only, so you must supply a compatible 14-inch wheel.

Will the 9/32-inch tread depth match the wear rate of older trailer tires I keep on the other axle?

The new tire starts at 9/32-inch tread depth; mixing it with significantly worn tires on the same axle can cause uneven loading and handling differences.
