Rear Tire Pressure

[Vision]

My bike runs beautifully with City Grips and 20lb in the front and 30lb in the back. For some reason the front tire never loses pressure but the rear tire won't stay at 30lb for long. The tire isn't punctured. After a trip or two the bike's agility starts to drop a touch and I know the rear tire is probably down to 25lb. Does anyone else experience this?

Inflate it and spray with soapy water. Look for a leak at the rim or valve stem.
Air loss is not normal on any bike in normal riding. It should take many days or weeks for a tire to lose air.

As Stig said there shouldn't be a pressure drop. I have not added air to my agility rear since it was installed 11 months ago. The front has stayed at 18psi and the rear at 34.

These are recommended values for your scoot?

In the manual for the City model, it's
1.5 bar front (21-22psi), 2.0bar rear (29psi).
Both tires are 16".

For what it's worth, my manual specifies 17psi on the front and 28psi on the rear for a single rider and 18-20 on front with 34psi rear for double up. I needed better breaking traction so I kept the front lower even with double.
