Hey mindful you did good,,, do you still have the tack that was in your tire? If you don't find one similar pick a spot on your tire the back one this time slowly press the tack into the tire all the way,,,, pull it out let all the air leak out,,, now take the wheel off the bike and then take the inner tube out add air to the tube so as to find the leak now go through the procedure of patching the tube ,,, that exercise will teach you a lot ,,,,,, good luck
