Hi, I have a used BMW 5 series which has Bridgestone Potenza 225/50R17 tyres (run flats) all round. Can someone tell me the correct tyre pressures in PSI for front and rear tyres…Thank You.
3 answers and 3 different answers. Come on guys give me an answer that’s consistant….
Following the recommendations posted in the driver’s door pillar is the right procedure. But the low tire pressure in front is disconcerting to some drivers.
If you can stand a tiny little bit of roughness in riding comfort, then you can increase the front tire pressures to 36 or 38 psi. You would hardly notice the roughness but could possibly gain a little more mileage due to less rolling friction.
If you are a stickler for rules then just stay with manufacturer’s recommendations.

Normal: 33psi front / 41psi rear
