This post is to advise anyone with Freightliner Chassis that has Trlangle Slotted Aluminum Wheels to check their rear tire inboard valve stems. They may have come loose from the rubber stabilizer and make contact with outboard wheel. This will cause the valve stem extension to wear on wheel and tire deflation is likely.
If you’ve had this issue, please contact Freightliner to see if involved in recall. If you have issue and being told not involved, Please contact the NHTSA website and follow instructions to file a complaint!
