Review on SUNLITE Black Thorn Resistant Tube with Schrader Valve by Jeffery Pricinoc

I have a 2020 Trek Verve 1 with 700x45c tires. It corresponds to a 700c beach cruiser tire (laughs), is wide and has plenty of air. Maximum tire pressure is 60-80psi. I usually pump up to 65. I have an stock rear tube and had to replace the front tube with a flat spiked one. I used about 4 tubes in a month and they all looked like a typical 700c tube. They don't fit, they can't even handle up to 40psi due to the large space in the 45c tire, the tube can physically expand too much and always fail. These Sunlite cameras are different. When you take them out of the box you will immediately see the difference. These are thick, heavy-duty tubes that are darn close to the thickness of my tire's sidewalls. Very heavy, not at all like a typical 35c pipe. I installed it and pumped it up to 65psi with no problems, rode it for 2 hours on our rough roads where I live without a single problem.
