Hi I've just treated my 1990 325 Cabriolet to a new set of tyres. Followed Zone recommendation a had Uniroyal Rainsport 3, 205 55 R15 V fitted all round. The pressures quoted on the door post decal are 2.4 bar front and 2.6 bar rear. Has anyone deviated from these pressures? Not for me to question BMW but these figures seem a tad high. Has tyre technology moved on from 1990 meaning pressures could be changed? I'd be interested in your views. Thanks in advance.

I used to run mine too low (32f 34r) as I was using 320i pressures when I first got my 325i. Putting the recommended pressure (34f 37r) really improved the ride and handling of the car.

Factory, as per door panel sticker, is fine for me on 205/55/15s all round.
