Tyres losing pressure

[whiffey]

Both my front tyres lose pressure. It's a Saxo VTS, low-profile Michelins, so not very noticeable. They are supposed to be 2.4 bar but after a week or so are often down to around 1.8 bar. I shall take it to a tyre place, but does anyone know the likely cause ? And why do they not go completely flat ? It seems worse in hot weather.

quite common on alloy wheels due to seals and dirt, could also be a slow puncture on both tyres. Get them checked out

My guess is that the alloy wheels are letting a small amount of air out, go to nearest tyre place explain and they will seal the alloy rim with a plastic type stuff, had to have mine done on a Frontera. pretty common with alloys.

it could also be that the valves need to be tightened up.

he Inner Rim of the wheel needs cleaning, Alloy wheel rims have this problem of loosing air.
