Dan,

When you say "plug", you mean you had a rubber plug put in the tire? I assume you don't mean you used the sealant. The plug in my tire is holding up fine. I've had numerous tires plugged while on the rim and not one has ever failed.

saldous,

The owner's manual doesn't clarify any of this. It does recommend having the tire inspected by someone authorized to sell/repair that tire. It doen't even suggest that further repair is necessary - just that it should be inspected. It also doesn't specify anything about replacing the tire or that the sealant causes damage. The references to sealants that cause tire damage are typically discussing the pressurized aerosol cans that are sold in automotive stores. They are somewhat different than the sealant bottle included with the Crossfire which isn't under high pressure. Some tire sealants even advertise that they are inert and can't damage the tire. I guess my argument is that if someone is temporarily stranded by a flat tire, and if the vehicle manufacturer-equipped sealant system will destroy the tire, the vehicle manufacturer would be obligated to mention this. In my case I was stranded late at night on an interstate, fortunately at a rest area. I learned that Chrysler roadside assistance doesn't provide any repairs (only towing to the nearest dealership). Since I was 600 miles from home that wasn't really a desirable choice. That's when I decided to use the sealant.
