ATV tyre for all-season off-road use
The Carlisle Knobby is built for ATVs and UTVs that tackle mixed terrain year-round. Its bias-ply construction holds shape under load, while the solid knobby tread bites into soft, loose and uneven ground. The tyre carries a 51 load index and F speed rating for speeds up to 50 mph.
Bias-ply stability and self-cleaning tread
The reinforced internal structure resists deformation, keeping the contact patch steady on rough trails. Knobs spaced around the full circumference eject mud, snow and rocks to maintain grip. A 19/32 tread depth provides material to withstand abrasion without adding rotating mass.
Upgrade from worn or less aggressive tyres
Riders replacing bald street-oriented tyres gain predictable traction on dirt, mud and snow. The jump is worth it when the machine regularly leaves hard pack for unpredictable surfaces. Buyers who need highway-only mileage or a quieter ride on pavement should look elsewhere.

Questions about this item
How do I mount this 25X12.00-9 tire on a 9-inch rim and what step is often missed?
Mount the tire on a 9-inch rim using proper lubrication and seating tools; the step often missed is fully seating both beads before inflating to the maximum pressure marked on the sidewall.
What maintenance or replacement will this bias-ply ATV tire need later?
Inspect tread depth regularly; replace when knobs wear down from the original 19/32 depth or if cuts, punctures, or sidewall cracks appear from off-road use.
What limit appears first during sustained high-speed runs on this 51F-rated tire?
The F speed rating caps sustained use at 50 mph; exceeding this generates excess heat in the bias-ply carcass and risks premature failure.
