Either the tyre place this morning misread my 60psi, and reduced it too low, or I have 4 tyres/alloys with a serious problem.
I've now topped them up to 37/40. I will keep an eye on them over the weekend.
Sound like you previously used a dodgy pressure gauge.
You've taken around 30psi out to find you are 30psi down on what you should be.
I doubt they all suddenly lost pressure if they held it before.
