Some customers may comment on a low tire pressure condition.
Diagnosis of the low tire pressure condition indicates an air leak through the cast aluminum wheel.
Porosity in the cast aluminum wheel may be the cause.
Important:
• | If the porosity leak is located in the bead area of the aluminum rim (where the tire meets the rim), the wheel should be replaced. |
• | If two or more leaks are located on one wheel, the wheel should be replaced. |
• | If the leak location is on the tire/rubber area, refer to Corporate Bulletin Number 04-03-10-001A or newer - Tire Puncture Repair Procedures for All Cars and Light Duty Trucks. |
• | If the leak is located on the aluminum wheel area, continue with the next step. |
Notice: Caution must be used when mounting the tire so as not to damage the sealer. Damaging the repair area may result in an air leak.
