If the motorcycle tire was properly plugged with a tire plug and the glue is allowed to dry for at least 15 minutes then you can ride your motorcycle on the plugged tire until the tire wears out.
A properly plugged motorcycle tire should be just as safe and long lasting as a tire patch and the tire should be okay until the tire wears out.
Although with a motorcycle tire it's better to patch the tire instead of plugging it especially if you are unsure on how to plug the tire.
But if you can plug the motorcycle tire properly then the plug in the motorcycle tire should last the life of the tire.
Motorcycle Tires last between 1,800 miles to 3,800 miles.
The more you ride the motorcycle the more often the tires are gonna need replaced.
Motorcycle Tires need replaced sooner than vehicle tires as vehicle tires can last up to 30,000 to 50,000 miles but motorcycle tires last a lot less miles.
