My brand new bike is losing 2-5psi per day in the tires. Is this normal or should I be concerned? (lemmy.ca)

I’ve been monitoring it for a few days. I carry a small portable air compressor and the digital gauge on it consistently shows the pressure being around 2-5 psi lower.

It seems the front tire loses air slightly faster than the rear but I can’t confirm that yet.

It seems I have to top up both tires before every ride now. I do around 80-150km per ride and measure inside a my garage before riding.

Should I be concerned? Is this normal? What has been your experience? Put my mind at ease one way or another πŸ€ͺ I just want to ride safely.

~~Just test without opening the valve either by pinching the tire with your hand or by putting your weight on it to see the deformation. Do this after topping up to get a baseline and once you think you lost pressure.~~

~~If it actually loses pressure you can find out where exactly the problem is, by taking the tire out, filling up your sink, pressurizing the tire (not as much as normally, as it is not confined), holding it under water and looking for bubbles.~~

Or use a tiny bit of soapy water instead of the entire sink. Also helps degreasing before applying glue and s patch to the leak.

Edit:lol thought this was about bike, but now see the motorcycle sub. Still with that big of a tire soapy water might be even more handy πŸ˜ƒ

I didn't catch this was about a motorcycle until their comment either!
