Purchased new inner tube for front wheel of Huffy Green Machine. Old tube measurement stated, 20x1.95-2.125. I took that measurement to bike shop. Was given a new tube with its box reading 20”x1.90”-2.125” I placed a squirt of air into the new tube to sit it in the rim. Put tube valve through wheel valve-hole. Began fitting tube around wheel, and under the tyre. It quickly became obvious the tube was too long. I took tube out and put about 10psi into it, thinking the tube with more air would squeeze onto the rim. Instead, it was clear that the tube was way too big for the wheel. See photo. Further, the tube looked like it was distorted (I tried to add more photos as seen in other posts, but I could only add one after resizing down to 40KB - APOLOGIES) I have read Q+As on here regarding the bulging issue – some answers saying it was a defect, while others saying it is normal.
So, 3 questions, please: A – Is the tube too big, or will it adjust once constricted by the tyre and wheel? B – Is that bulge normal? C - The tyre recommends 40psi, yet the tube is bulging at 10psi. Should I pump another 30psi into it when it is placed back on the wheel? Thank you.
