This is from their site.

Ride-On is not designed to protect the outside 1" to 1.5" of a tire's tread closest to the shoulder areas.
The effectiveness in sealing punctures in the crown of the tire is an estimated 85 to 95 percent in tubeless tires. Effectiveness in
puncture sealing drops to about 55 to 65 percent in tubed tires, since there are two membranes involved and since tubes have a
tendency to tear or rupture when punctured.

If it doesn't protect the outside of the tire, 1 to 1.5 inches it is almost worthless. This is almost the entire tire considering you are talking about 2 to 3 inches of the entire tire. Then if the nail hits the center of the tire you have a 55 to 65% chance it works. It "does" give minimal protection. (I stand corrected!) Don't want to stir anything up. I guess it is better to have a chance than none!
