Default Tire pressure 1psi loss/week normal?

I'm running 20" tires and I noticed a slow loss of pressure. I pump the front tires to 40psi and in a little more than a month, they will drop to 35. This has happened a coupe times already. Is this rate of psi loss normal?

Is this happening with one tire, or all the tires? If all the tires, what width rim and tire are you running? Could be you have a bad fitment.

20x8.5 and 20x10 20mm offset AVG wheels w/ 245/35/20 and 285/30/20 Sumitomo HTR Z III tires. Fitment should be spot on. This is happening to the two front tires. Setup is also fairly new (less than 6 months)

Either you have a hairline crack, bends in you front wheels or you have a bad bead seat on them. Being that you mentioned it only being less than 6 months I highly doubt your wheels a cracked unless you purposely look for potholes.

Default Loss of tire pressure

In my case, I had a similar problem with one tyre. It ended up being a faulty valve.

Maybe remount the two front tires and see if the problem goes away?
