Improperly Cured Tire Tread May Detach from Tire

Tread detachment can cause a loss of vehicle handling and control, increasing the risk of a crash.


NHTSA Campaign Number: 24T004

Manufacturer Rocky Mountain ATV/MC, Inc.

Components TIRES

Potential Number of Units Affected 900



Rocky Mountain ATV/MC, Inc. (RMATV) is recalling certain Tusk 2Track Adventure rear motorcycle tires, size 150/70B-18. The tread layer was improperly cured, which can result in sections of tread detaching from the tire.



The remedy is under development. Owner notification letters are expected to be mailed May 15, 2024. Owners may contact RMATV customer service at 1-801-465-3140.



Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.


Chronology :

On April 3, 2024 RMATV was notified by its supplier that certain tires sold to RMATV may have deviated from design specifications in a manner that could pose a risk of tire chunking. The supplier advised that while quality control testing of the production lot sold to RMATV had detected no manufacturing flaw, similar testing of a later lot identified a potential deviation in the vulcanizing process.

RMATV immediately stopped selling the identified model and initiated an investigation in coordination with its supplier to determine the cause and potential consequences of this reported issue.

RMATV has now determined that a potential safety risk due to insufficient curing time cannot be ruled out and decided to conduct a recall.

RMATV is aware of no reports of crashes, property damage, fatalities, or injury related to this defect.
