Lawn & Garden Tire 480/400-8
The Hi-Run WD1086 is a lawn and garden tire built for utility equipment such as mowers and small trailers. Its 4-ply rubber construction supports a 670 lb weight capacity at the specified inflation pressure. The rib tread pattern delivers straight-line stability on grass and hard-packed surfaces.
Thermals Noise and Power Draw
As a passive rubber component the tire generates no operational noise and draws no electrical power during use. Heat buildup is limited to normal friction from rolling contact and remains within the design limits of the 4-ply casing. Proper inflation to 70 PSI maintains the intended load distribution and temperature profile.
Bundled Accessories and Software
The product is supplied as a single tire only with no wheel, valve hardware or mounting lubricant included. No software or digital tools accompany this item. Installation requires a compatible 8-inch rim and standard tyre-fitting equipment sourced separately.

Questions about this item
How do I seat the 480/400-8 tyre on the rim and inflate it to 70 PSI without the bead slipping?
Mount the tyre on a clean 8-inch rim, lubricate both beads, then inflate rapidly to 70 PSI so the ribs pop into the bead seats; check alignment before final torque.
When should I replace this 4-ply rib-pattern tyre instead of just adding air?
Replace it when tread depth reaches the wear bars, sidewalls show cracking, or the carcass cannot hold 70 PSI without bulging.
What fails first if I run the mower continuously at the 670 lb load rating?
The 4-ply carcass heat-build-up at 70 PSI will degrade the rubber compound before the rib tread wears through.
