so every week or so I have to fill all my tires with air. I read that tires lose pressure over time, like around 1 psi a month. I fill it up to about 40-45 psi and a week later it goes down to 25-30 psi when I'm back filling it up.
only thing I can come up with is they need to be resealed... if they do, where can I get this done? I was thinking Fountain Tire... I'm in Edmonton at the moment.
