Hello,

On my D3 4.2 tdi Quattro sport, I 255 40 19styres, dunlops all round.

The tyre pressures on the petrol flap advise me 44 front and 38 on the back, am happy with 37 to 38 all round ( I have the sport model, so it's a harsh ride on bumps in town, but brill on motorways), but not sure why I need 44, is it to do with weight of engine?

Not sure if this relevant, but I mainly use the automatic suspension settings, and now and then will revert to the using the tilt? setting over very bad roads around town.

What do you use or recommend?

Most of my drive is on the motorway so no extra weight.

Thanks
