Pneumatic lugs, industrial pneumatics and solid resilient compounds — matched to surface, hours and maintenance discipline.
The options
| Option | Where it wins | Watch for |
|---|---|---|
| Pneumatic (aggressive lug) | Rough, soft and uneven ground; the RT40’s fitment | Pressure discipline; debris cuts |
| Pneumatic (industrial tread) | Mixed yard-to-dock duty on harder surfaces | Wear rates on abrasive concrete |
| Solid (smooth or patterned) | Debris-heavy yards and long indoor hours; no flats | Harsher ride; transmits impacts to the drivetrain off-road |
| Solid resilient (aperture) | Heavy counterbalance on mixed hard surfaces | Heat build-up at sustained high speed |
Selection logic
Surface decides the construction: the ground survey in the rough-terrain selection guide applies verbatim — soft and broken ground wants pneumatic lugs with 4WD; debris-hardened hardstand wants solids.
Hours decide the economics: compare on cost per hour from your own wear logs rather than per tire; solids cost more up front and often win the hour math on debris routes.
Discipline decides the life of pneumatics: a weekly pressure check is the whole maintenance program, and skipping it is how new pneumatics repeat the old failure clock. See the solid versus pneumatic guide for the full trade.
