How long should a road tyre be able to maintain a pressure of around 100psi, and what factors are likely to reduce this time?
My tyre pressures are consistently dropping to around 60psi after about a week (three commutes, total ~50 miles), which makes the bike feel sluggish and less responsive.
I've only recently got a road bike, but I've always had mountain bikes - they've always held around 30 psi for weeks and weeks with no problems. I'm wondering if it's the higher pressure that's causing my tyres to need inflating more frequently, or something else?
This answer to another question, and some other answers I've seen suggest that you should check your tyre pressure every day, but is this to be cautious or are you likely to actually have to inflate your tyres every day?
