Today while checking cycle after yesterdays' ride, found what look like a pin in middle of rear tire. Sprayed with water , no leak. Through the object was not in the tire deep enough to cause leak. Pulled the object out which turn out to be a small wire less than the size of a pin and now it have a real slow leak. The tire have about 65 to 75% wear left. Would it be OK to put a sealant such as "Ride on or other in for repair????
