I have a Citroen C2 can anyone tell me what the tyre pressures should be for Michelin's 175/65 R14

The best advice is phone one of the Citreon branches, you can get the number of the internet. If you dont have access to phone then l will try and find out for you.

between 30 and 32 psi l work in a quick lube

l believe its 50 psi max pressure

it should be on the inside of drivers door or ur owners manual. but 35 as been the normal pressure for most tires for 25 yrs the max tire pressure is on the tires side wall so where between that & 30 what is recommended by auto marker is just that recommmened it is up to driver to watch for tire wear & adjust to keep tires from wearing it depends on the roads u drive & out many people ride in car as well 35 pounds should be fine..tire service guy 35 yrs but this web site u can up it up it says 30 but its still up to driver to adjust for wear

2.2bar (32psi) all round. Guaranteed. Not a guess & not a figure off the top of my head. It is from Dunlop is website.
It should be on a label on the front door pillar & also in the handbook.
