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 🤪 I just want to ride safely.

Nah shouldn't lose air over a couple days as everyone else has said.

Fill a spray bottle with soapy water and spray around the valve stem and bead (where the tyre meets the rim) look for bubbles.

Or check it then don't check for a week and check again and see if it's a bigger lose.

You will feel low pressure tyres when riding especially in corners.

All good advice. I’ll check for air leaks while I wait for my proper gauge. To be honest my bike has felt fine handling wise. No problems with taking twisty roads at speed. I’m hoping I just have faulty gauges.
