You can get a free app called Tyresafe, it tells you what the psi should be for your cars' tyres.

If you don’t know the correct pressure for your car’s tyres then look no further than the TyreSafe app. Simply enter your vehicle’s registration details and the app will confirm the vehicle type, tyre size and manufacturer’s recommended pressure settings in both psi and bar.

Dont have iphone but im ridiculous at looking after my car. I never check tyre pressure & at least 3 times a year end up in kwik fit thinking iv a puncture when the airs just a bit low

As for water & oil, my mechanic who's a family friend tops that up for me once a year in Jan at the service. Id have no clue how to do it myself. OH clueless too as he cant drive.

I could have done with this one the other day. Mine should be 31 (or 2.2) and they were only 16!! Eeeek!

No wonder I was wasting so much petrol!
