Mud tire warranties compared
Highway tires advertise mileage warranties. Mud-terrains mostly don’t — and the reason why tells you something useful about what you’re buying.
What we found published
Across the tires we have documented, exactly one publishes a clear warranty term, and it is time-based rather than mileage-based.

“None found” means we could not locate a published term in the sources reviewed. Warranties may exist in dealer documentation we have not seen — check at point of sale.
A time-based term covers the failure mode that actually affects low-mileage trucks: rubber ageing out before the tread wears.
Why mileage warranties are rare here
A treadwear mileage warranty is a bet by the manufacturer about how the tire will be used. For a highway tire, usage is predictable enough to price that bet. For a mud-terrain, it isn’t — the same tire might spend its life on pavement or be chunked to pieces on rock in a single season.
So the absence of a mileage warranty is not necessarily a statement about quality. It is a statement about how unpredictable the use case is. It does mean tread life is a risk you carry rather than one the manufacturer shares.
Why a time-based warranty is worth more than it looks
Mud-terrains are disproportionately fitted to vehicles that cover low annual mileage — weekend rigs, work trucks used seasonally, project vehicles. On those, rubber often ages out before the tread wears out.
A six-year term from date of purchase covers exactly that failure mode, where a mileage warranty would be worthless. If your truck covers modest miles, read that as a genuine benefit rather than a weaker offer.
What a warranty rarely covers
Off-road damage is the standard exclusion, and it is the damage most likely to happen to these tires. Cuts, punctures, chunking, impact breaks and sidewall damage from rock are generally treated as road hazard rather than manufacturing defect, and road hazard is usually a separate product sold by the retailer.
If you genuinely wheel the vehicle, a retailer road hazard programme is more likely to pay out than any manufacturer warranty. Price that in at purchase rather than after the first cut.
What to ask before you buy
Ask for the warranty document rather than the marketing page — terms, exclusions and the claim process. Ask whether road hazard is included or sold separately, and what it costs. Ask what proof of rotation the manufacturer requires, because missed rotations are a common reason for denial on any tire.
And keep your receipts and rotation records. A time-based warranty is only as good as your ability to prove the purchase date.
