Warranty Information and Warranty Claims Procedure



Warranty: CST warrants to the original retail purchaser (“Purchaser”) of every new CST brand bicycle tire, including but not limited to the CST website, and used exclusively in North America (“Tire”) that the Tire will be free from defect in material and workmanship for up to one year from date of purchase or until there is no serviceable original tread depth (as determined at the reasonable discretion of CST) remaining on the Tire (“Limited Warranty”).

Remedy: CST will replace the defective Tire with a comparable new CST brand tire. Any applicable taxes are not covered by the Limited Warranty.

Tire Exclusions: The Limited Warranty does not apply to damage or defect relating to: (1) road hazards (such as cuts, snags, punctures, or bruises), impact breaks, tire plugs and/or repair, vandalism, accidents, or abusive or unusual operating conditions, fire and/or chemical corrosion; (2) improper operation or maintenance such as, but not limited to, under or over-inflation, load, speed and inflation practices resulting in excessive operational conditions; (3) improper sizing, wheel alignment, Tire mounting or rim fit; or (4) bicycle mechanical problems (such as faulty, worn, or malfunctioning brakes). CST does not condone the use of liquid sealant with any CST tires. Use of liquid sealants with any CST tire will void warranty.

Tube Exclusion: All CST bicycle inner tubes are inspected and tested after production to be free and clear of any manufacturing defect. Due to the high frequency of user error during the tube mounting process, all CST bicycle inner tubes are not warrantable.

Warranty Disclaimer: Except as stated above and unless otherwise provided by law, there is no warranty of merchantability or of fitness for a particular purpose or any other warranty, express or implied.

Limitation of Remedy: Replacement of the Tire is the sole and exclusive remedy in the event of breach of any warranty or of any agreement relating to the tire.

Limitation of Liability: In no event shall CST be liable for any incidental, indirect, special or consequential damages or liabilities (including but not limited to incidental or consequential damages for loss of time, inconvenience, loss of use of bicycle, or any other consequential or incidental loss) in connection with the purchase, use, or operation of the tire, whether due to a breach of warranty, breach of contract, or otherwise.


Limited warranty only applies to original retail Purchaser. To begin the warranty claims procedure, Purchaser must complete the CST Bicycle Warranty Claim Form located at CSTtires.com.

Once the CST Bicycle Warranty Claim Form has been submitted, CST Warranty Claim Center will confirm receipt of the claim, and begin evaluation of the CST Bicycle Warranty Claim Form. During the evaluation period, do not dispose of the potentially defective tire. CST Warranty Claim Center may require a physical inspection and/or additional photos/information before making a final claim decision. Once the warranty claim has been fully evaluated, CST Warranty Claim Center will notify Purchaser of final claim outcome.

If Purchaser’s warranty claim is accepted, CST will ship replacement tire(s) to Purchaser freight prepaid by CST. If an exact replacement is not available, CST will coordinate with Purchaser to find comparable replacement tire(s). However, if warranty claim is not accepted, tire(s) sent to CST Warranty Claim Center for inspection will be returned upon request freight prepaid by Purchaser. If CST does not receive a request for return or prepaid freight within 30 days of claim decision, CST will dispose of the tire(s).

If you are a dealer and you choose to submit your customer’s warranty through the distributor where you purchased said product, please follow that distributor’s warranty claim procedure. If the distributor provides said service, they are doing so voluntarily and you are subject to any and all of the individual distributor’s warranty program rules and regulations.

If you are a dealer or distributor and a customer returns a tire to you for possible warranty and you warrant said tire, you do so willingly as a service to your customer. If you would like to submit a warranty claim to CST for your customer’s tire, please contact CST Warranty Claim Center at 866-509-7067.
