Customer Service

NOTE: This contact form is for general customer service questions and information requests only.

WARRANTY REQUESTS MUST be made using the specific “Warranty Request” forms – for Tires or Wheels – accessible under the CONTACT drop-down menu. Any Warranty Requests or inquiries left using this Customer Service form are not guaranteed a quick response.

STI does not sell tires and wheels directly to consumers. All questions about pricing and availability should be directed to your retailer. STI Tire & Wheel products are available exclusively at approved retail powersports dealers through MTA Distributing (U.S.), and Motovan (Canada). Please contact your favorite powersports retailer and ask about STI Tire & Wheel products. 

For general customer service questions or information use the form below to contact us. Responses will be sent during STI office hours Monday through Friday 9 am to 5 pm PST.
