After tube installation only add about 8-10 PSI to cause the tube to start forming to the inside of the tire. INSPECT the tire beading to the rim to ensure the tire is hooking completely and evenly all around the rim and on both sides. NEXT, inflate tire to approximately 25 PSI and repeat the inspection of the tire beading to the rim EVENLY all the way around and on both sides. IF it looks evenly beaded then add another 20 PSI and check again. If okay then you can go ahead and inflate the recommended pressure as indicated on the side of your TIRE. 2 Tubes New In Box 700x20-25 (27x1) ISO 622 48mm Schrader Valve Be sure the tire bead is seated evenly all around the rim by first adding a little air to the tire, checking the bead on both sides and if beaded properly continue filling air to the correct pressure as stated on the tire.
