I really need some advice on puncture sealer. Found several brands, but can't decide which is best for large tubbed tires. "Ride ON" brand will balance as well as protect against flats, but only coats the center of the tread. Another brand coats all of the tire's inside and protects against all flats including bead leaks, but does not balance. Mostly in the past I have used "Victor EZ Seal", but they seem to be out of business now. Some help here would be greatly appreciated.
