Seems quite low Del, I generally run 38/39 front and 40/41 rear.

I'll give your suggestion a whirl though

I was told by BMW to run between 38-40 at the rear and 36-38 at the front.

I know they're different side wall heights Ian, but the M3 runs 33psi front 35 rear, which works ok

Sorry Del, I thought you were referring to your 335i not the M3.

I was with the 34 -37 psi post Ian

The M3 is 33 -35 psi.

Ahh, so 335i was 34/37.
M3 is 33/35.

The M3 pressures make sense, but the 335i's seem low, hey ho!

I know nothing about the price of fish

Me neither Mate, out of interest, why do you say they sound low? considering the sizes were almost the same, except wall height.

The wall height is the difference Del, you have more give in the wall on the M3 than the 335i (Non run flat!)

What tyres are on the M3, OEM's?

Yes- well OEM spec, I bought new Conti's with the wheels.

Just realised, there is a 13mm difference in wall height

That's quite a cushion over the rubber bands on the 335i/d 19" variants.
