What does it say on your filler cap? The tyre pressures are on there.
For my PD140 its 32/29.

Nope they stay the same. I have 18s on mine and keep to the same tyre pressures.

Look at a psi list at a garage or motor factors if your unsure.I reckon should be about same or only a couple of psi more.Halfrauds may have the info.

35psi all round would eventually wear the middles out same as 30psi all round will eventually wear out the edges of the fronts a bit but near enough ok for the rears.Best off sticking to the correct spec: which is 29psi rear and 32psi front with normal load,unless you drive all over with 4 passengers and/or a large load in the boot. Give or take the odd psi. NEVER EXCEED 32 or 33 psi EVER or buy new tyres sooner.

but with a different size tyre in my case being larger wouldnt the new tyre need more psi to fill as the older was smaller or am i just being thick?
Air pressure remains the same, whatever tyre size goes on.
Ok I'll drop them to that but iv just top them up after bein on hol to 35psi and they feel loadz better
A larger tyre size only means you need to put more in to fill it = volume. psi remains the same.
Only more air needed.
