Can I have an opinion on what I should inflate my tyres to as I'm unsure.

size is 235/35r19y

was thinking 32psi?

[51M0N]

Sorry wrong section. on my phone 

[TheBoy]

235/45/17 is stated as 32 psi (for non loaded, non high speed), so wonder if your lower profile should be a bit harder  :-/

[cem_devecioglu]

depends on your daily commute roads.. if they are ok you can use 32 psi.. otherwise I wouldnt go down below 35 with those tires without risking them..

[51M0N]

Normally to and from work. just me in the car 40mph or so

34 perhaps?

My Old Beemer had staggered Alloys 235-35-19 on the front that was 38 PSI and the rears were 265-30-19 they were 45 PSI.

So I'd say around 38.

I have more or less this set up on my Mig Estate ('cept 275/30 /19 on rear)

- you need 'em that hard when cold?
What room for expansion when everything gets hotter?

Agreed with DELBOY, i had 38psi when i had a set of 19s on mine!

my tyre size is the same all round. so 38psi all round on a 235/3519 then folks?

imo ,  really it depends on the road quality and your driving style.. however when the weather becomes hot you need to drop a bit..

[51M0N]

roads are terrible, potholes speedbumps etc

[feeutfo]

So are we purely pumping up tyres to protect wheel rims from buckling on poor roads?

Because ideally an increase in load would be the only reason I'd increase psi. Otherwise the ride must be painful at 38psi surely....?

[feeutfo]

Grip must suffer as well I would have thought...?

[51M0N]

no grip at all in the wet. just kicks out, all tyres are currently on 36psi

They're the pressures BMW recommend, so I'll agree with BMW
