I think that would depend on what type of tires the vehicle has. The best thing would be to ask a tire shop.
For long wheelbase high top 1800 (2003) the recommended pressure is 65 p.s.i.
pressures
its printed on inside of your drivers door,,,,
read the tire pressure max on the tire that is what the tire manufacture recommends you to run if they recommend you to run 35 i would run 32 in the rear
35 front and back.
32psi front tyres 34psi rear tyres
I only know the correct tyre pressure for a Citroen Picasso , not a Citreon Picasso - sorry
2.4 Bar/ 34 PSI back/front
0n a 2004 tyer pressures are 65lbs all round. on inside of drivers door.
Front 2.0 bar Rear 2.2 bar Note: this is for a loaded car
Tyre pressures for a Citroen C3 standard tyres Front 30 PSI (2 bar) Rear 33 PSI (2.2 Bar)
Look at the tyre itself and there you find the tyre pressure e.g 35 psi. I inflated mine and the sensor when off.
