Hi just wondering what the correct pressure is for these tyres, they are bridgestone 205/40r/18 runflats, currently i run them at 34PSI but i'm not sure this is correct.
I rarely have more than two people in the car.
Thanks in advance for any help :)

Did you look on the driver's side door jamb? Mine says 38 psi cold. I have the 205'45'17 run flats. I'm running about 35psi as I believe the 38 psi is a maximum pressure.

Hi yeah its in bar though and i'm not sure if one there are different levels for the front as opossed to rears?

Front and rear pressures should be separated. The third is for the spare, which should be blank because you probably don't have a spare with run flats. Mine shows the same pressure for the front and rear.

I have a sticker inside my door and on the table for the 205/40 R18 82W it says:
For 2 people 2.8 Bar / 41PSI and for 4 people 3.0 Bar / 44PSI for both front and rear tires.
I have the 205/45 R17 84W and i put for all four 38PSI (2.6 Bar).

By the way, i put nitrogen in my tires, so the heat will be less and the pressure will be much more stable.
