i used the tirefit while driving my crossfire home for the first time. the hole was relatively large so the sealant leaked out and would not seal the puncture. i was able to get a roadside assistance co. to come out and plug the tire. chrysler roadside assistance will only tow you to the closest dealership - they won't repair a tire. not very helpful when you're 600 miles from home.

my recommendation to anyone driving a crossfire is to buy a vulcanized rubber tire plug kit (costs $5-10 at any automotive store) and keep it in your car along with needlenose pliers (to remove nails, etc.) then use the compressor to fully inflate the tire. the little compressor works quite well.

the tirefit system may successfully plug a small hole, but it can also affect your tire valve and pressure sensor. a couple weeks after using the tirefit i conducted an experiment and let air out of the repaired tire. the low pressure indicator came on. i inflated the tire back to its normal pressure and it went off. good i thought - the sealant had no negative effects. but then half a year later the low pressure indicator comes on and stays on. the valve had eventually become clogged from the sealant. i couldn't add air to the tire or take it out and couldn't even get a reading on the tire pressure. fortunately, it is under warranty and was fixed by a dealership.

using tire plugs and the compressor eliminates any need to use the sealant.
