Customer Service

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

We are happy to provide help and service to all who visit here. But before you send your question, we might be able to save you some time. Our site has loads of info that might answer your question immediately.
1. Searching for Center Caps? Part Numbers and shopping info can be found on the Center Caps page, under the Wheels menu.
2. Tire Weight? The specification charts on each tire’s product page shows tire weight.
3. Product availability questions? Please contact your favorite dealer.

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 tires and wheels are available at approved retail powersports dealers, with distribution handled by Parts Unlimited, the world’s largest distributor of powersports parts and accessories. Please contact your favorite powersports retailer or use the Dealer Locator tool here.

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.
