First, a question...are you running the Kenda Spyder tire or an automotive replacement?
Kenda motorcycle-rated tire:
These tires have a thinner tread, which may not hold a repair well. On a conventional motorcycle tire, it is not recommended to run a plug more than 50 miles or so...just long enough to get to a shop with a replacement tire. The thin treads will not hold the repair for very long...the plug will work itself loose. The Spyder tire has a flat tread, is thicker, and is more like a car tire. It will hold a repair better, depending on the location. Some owners have run them until the tires wore out. A cut, instead of a round puncture, will not hold as well. I'd monitor the tire pressure closely for a while. If it holds air, fine...if not, replace the tire.
Automotive tire:
An automotive tire should hold a repair well, in the tread area. There is more meat and belt to hold the plug...and less movement. Still, a cut is harder to seal. Monitor the pressure, and run it if it doesn't leak.
Slime:
Slime will definitely corrode either alloy or steel rims. Ride-On, on the other hand, is formulated to inhibit corrosion. It is definitely a better product...especially for aluminum rim use. BTW, Spyder rims are powder coated, so corrosion is probably less of an issue. I still would never use Slime, except maybe in a tractor tire. The tire changer will cuss you out if he has to change a Slimed tire. I would not hesitate to use Ride-On, however.
