Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering tires on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This Preliminary Information communication provides information to the technician about vehicles with tire sidewall irregularities. This is a visual condition that will not affect durability, reliability or performance of the tires. Dealer should communicate to the customer that slight sidewall indentations are a common characteristic of radial tire construction.
