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.

That is not normal at all. You should get them checked out.

Yeah what he said. Your bike tires should hold pressure over a season. I have to add air to my motorcycle tires maybe twice a year.

That being said, I wouldn't count on the gauge on a shitty compressor to be accurate. Get yourself an accurate tire pressure gauge and check it over a couple days without riding it in between to make sure it's really losing pressure sitting still. If it is, fill it up and take it back to the dealership and tell them to fuckin' fix it! And don't let them 'fix' it by putting slimy sealant in your tires. That shit is a mess to clean up when you do a tire change, and it's just a band aid. You want to know if they sold you a bike with defective rims or tires, basically.
