I had my first flat tire today and found out they want $55 for the replacement sealant. Any problem with just using a fix-a-flat product from the auto parts store rather than the GM factory replacement part. Seems very high priced for a sticky rubber product.
One of the first Rules of Thumb I learned here is to not use the $500++++ much too complicated tire factory inflator thingy!!!! I have a couple of large cans of flat fixer and a Wal-Mart plug kit for extreme emergencies. But my cell phone and AAA membership and Corvette 800 number are always handy. In addition, having replaced my front tires just last week with Toyo T-1s, I now have 2 spare tires sitting around--eventhough my dealer was able to get the Toyo's in one day!! :thumb:
