New CPC 5 german tyres fitted in car barely 2 months ago.
Recently had 30psi air filled in all tyres from a fixed pump tyre shop.
After 7 days went to get air filled from the same pump tyre shop and noticed:
Both Right side tyres were 29psi.
Both left side tyres were 27psi.
Car was driven minimally 4 days almost alternating days.
Is it normal to loose air like this on new tyres?
There seems to be no puncture. Could this be an issue with the nozzles? Tyres were bought from japan tyres blue area.
