Using the pump, inflate the tire to the pressure recommended on the sidewall.
As you put air into the new tube, be sure the tire is filling consistently. Any uneven inflation that you notice, such as a bubble or highly inflated portion of the tire while another part remains flat, tells you that your tube is pinched or twisted inside the tire and needs to be reset. Correct this by letting the air out of the tube and repeating Step Two, which allows you to look for the spot that is pinched or twisted. Many times you can fix this without removing the tire completely again. Replace the tire as you did in Step 7 and try inflating the tire again.
