Trailer Tire for Highway Towing

The Trailer Master ST PRO+ is a highway terrain, all season tire built specifically for trailer use. It carries a load index of 129/125 and a load range G with a 14 ply rating for heavy loads. The speed rating M allows operation up to 81 mph. This tire must not be mounted on light trucks.

All Season Traction and Stability

The ribbed tread design and all season compound deliver grip in wet, dry and winter conditions. Wide circumferential grooves channel water and slush away to reduce hydroplaning risk. The reinforced internal structure maintains the ideal tire shape under load and driving pressure for consistent controllability.

Longer Tread Life Design

The optimised tread pattern and durable compound work together to slow treadwear and extend usable life. Tread depth measures 10/32 inches when new. The rim is not included; product images showing a wheel are for display only.

Questions about this item

How do I install the 235/80R16 tire on a 16 inch rim, and what step do people get wrong?

Mount the tire on the 16 inch rim with the correct load range G orientation, then inflate to the pressure moulded on the sidewall; the step often missed is verifying both beads seat evenly before final inflation.

What maintenance or replacement will the 10/32 tread depth tire need later?

Inspect tread depth regularly; replace when wear reaches 2/32, and rotate periodically to even out wear across the 14 ply construction.

What limit shows up first on the ST PRO+ under sustained highway use at 81 mph?

The M speed rating of 81 mph is the first limit; sustained speeds above that can overheat the all steel casing despite the reinforced structure.
