I found all around 2.5 bar perfect and the most comfortable ride, however, the tyre pressure monitor doesn’t seem terribly accurate. I find it over states the position. Oddly over the past few weeks the pressures are reported to have gone up and stayed up.

Checked the pressures again as delivered from new last week. They were all 3.1bar!!
Have to admit Darlington Drive MG not the best. So obviously didnt check tyres during PDC.

Lowered to 2.6 at moment and see if any better later when I go out.
If still a rumble, hopefully get the Bridgestones swapped for Cross Climates with a part exchange deal.

We have an S5 and an HS PHEV. The TPMS doesn't seem that accurate on either - I put the tyres up on both cars to 37psi today, as per the manual, and the difference in ride was very noticeable and not in a good way.
