Re: OK are you ready for this one
I'm sure all the Crossfires came with the kit.
Older years have tire sealant with expiration dates that have been passed now.
I don't recommend the sealant anyway as it ultimately ruins the tire.
I suggest you do as many others here have.
Buy a good tire plug kit and a good pair of needle nose pliers.
If the situation occurs you can remove the object from the tire and install the plug.
Then use your tire inflater to fill the tire back up with air.
This can usually be a permanent fix in most cases.
