This is completely 'suck it and see'. Depends on tyre - car - driving style - your personal preferences ref comfort etc etc

Just use the pressures on the label that BMW put on the B pillar. :)

Agreed. And the more I get into this it's also about achieving the right balance Front to Rear.

But early days for me in the NRFT pressure debate (which I think has the potential to rival the Manual vs DCT argument in terms of having no single acceptable answer).

Then BMW, Bridgestone, Goodyear-Dunlop, Michelin and Pirelli must be wrong, too. :)

If you say so, I'm still working on the theory that you don't have a clue about anything and you just get some sort of sexual thrill from being annoying :roll:

I wouldn't run the pressures that are recommended for run flat tyres. Use them as a guide then lower them until the car feels good to you.

The most important factor is how the car feels and the traction. Don't get to hung up on the numbers.

It is a lot, definitely feels better for it imho though :driving:

I forgot to ask, Rob. Do you still have RFTs on one axle and non-RFTs on the other?
