Review on 🚲 Sunlite Street Fit 360 Tube, 27x1-1/4, Schrader Valve, 32mm by Tim Springer

Two tubes burst on inflation around the valve. I installed them first with some air in the chamber, put the tube and tire on the rim and pumped and deflated the tubes several times before inflating them to normal pressure. The inner tubes burst before the normal tire pressure is reached. This is the first time my tubes have burst on initial inflation. I've been doing this for many years. The tubes I received were wrapped in cellophane labeled Sunlite. They didn't come in the box as advertised on Revain. The label says Made in China. After those two tubes failed, I went to a local bike shop and bought two boxed Sunlite tubes that were made in Taiwan. A tube I used from LBS is fine and fits my bike. The Revain Sunlite lamps were ordered three months ago and are therefore out of warranty. I keep the tubes handy so the apartment isn't such a big deal, they don't necessarily need to be used right away.
