Lawn and garden tire
The Hi-Run WD1280 is a new riding mower tire built for lawn and garden equipment. It carries a 4 ply rating and a weight capacity of 1,040 lb at a maximum pressure of 24 psi. The tire uses a rubber construction with a SU12 tread pattern and a tread depth of 7.6 in.
Thermals noise and power draw
As a passive rubber component the tire generates no operational noise and draws no electrical power. Heat buildup is limited to normal friction during use and stays within the design limits of the 4 ply structure. No active cooling or power management is required.
Build quality and connectors
The tire only product weighs 10 lb and measures 18.1 in outside diameter with a 9.50 in section width for an 8 in rim. It is DOT approved for NHS meaning not for highway service so it must stay off public roads. California Proposition 65 applies due to chemicals known to cause reproductive harm.

Questions about this item
How do I install the Hi-Run WD1280 tire on my riding mower and what step is often missed?
Mount the tire on an 8-inch rim, inflate to a maximum of 24 psi, and ensure the bead seats evenly; the step often missed is checking bead seating before full inflation.
What maintenance or replacement will the Hi-Run WD1280 tire need over time?
Inspect the 7.6 in tread depth regularly for wear and cracks; replace the tire once the tread wears down or if the rubber degrades beyond safe limits.
What is the first limit reached on the Hi-Run WD1280 tire during sustained heavy use?
The 1,040 lb weight capacity is the primary limit; exceeding it risks tire failure before the 24 psi pressure limit becomes a factor.
