Tire Chip & Chunk: Action

When a customer contacts a retailer concerning the chip and chunk phenomenon, dealers must: 

• Conduct a thorough evaluation of the tire condition and, where no detrimental damage has occurred, inform the customer that the chip and chunk condition does not affect the overall tire integrity or significantly affect performance
• Inform the customers of the conditions that generate chip and chunk phenomenon

Complaints associated with this phenomenon must initially include a thorough examination of the vehicles tires for the following: 

• Excessive chip and chunk (tread cuts or loss of tread block section, extending deep into the tread rubber beyond the tread wear indicators or in the shoulder area extending beyond the groove depth)
• Cuts and bulges especially within the sidewall
• Overall tire condition including tread depth.

Where the tires do not exhibit excessive chip and chunk, cuts, sidewall bulges and are in generally good condition the customer should be advised that the condition does not affect the overall tire integrity or significantly affect performance and as such are serviceable.
