Just checked mine, and they were a bit out.
Front Passenger: 32psi
Front Driver: 29psi
Rear Passenger: 30psi
Rear Driver: 29psi
Firstly, could this account for any drop in MPG? Can't see it myself, not enough to notice anyway..
Secondly, what is the recommended tyre pressure for the Meega? My tyres are only babies.. 185's.. I have set them all as 33psi for now, but could do with a recommendation..
:)
-
According to manual, should be 30psi front and back... unless under load - front 36, rear 42 - for all models except 3.0/3.2.

I run mine @ 31, just for the hell of it.

That always struck me as an odd statement... So "under load" I suddenly put another 6lb in the front and 12lb in the back? At what magic "load" should this happen? Surely I should gradually increase the pressure depending on the load, up to a maximum when "loaded". But I can't even start to calculate that without knowing the definition of "load"... :(

Same here, book says 30.5.
I put them at 31.
-
I personally run 35 in front and 32 in rear. This is a result of 1 yr of pressure fiddling...
-
my car came with no books, and also, i changed the wheels to elites on 235/45/17s, what should my tyre pressure be? they say on the actual tyre Max 51psi but obviously ya dont go anywhere near!

The 235s on prefacelift MV6 are stated at 32 all round, or 38F and 45R for load...

Same size wheels as mine I run them at 32 lbs psi all round
-
225/55/16 on mine and book at 30 all round
-
i think mine are at 35
i load it up with post bags every mornin anyway, dont know whether that has much of an effect!
-
running stock size 205/65 R 15 and running 32psi all round

"Under load" means carrying 3 or 4 passengers and luggage (according to handbook) or, more accurately, standard tyre pressures are for carrying up to 3 persons. Estate pressure are different again. :y

do you not get any uneven wear @ 35?

I'm actually getting the opposite of what you would expect - edges wearing...
-
I am 32psi all round, i check them each week, as i like to be safe on the winter roads
my ride quality is really smooth too
-
I do 32 all round with more in the back if I'm lugging heavy stuff from B&Q.
I also get the wear at the edge problem on the front - not sure its pressure related though.

Inside edge is common on Omega, and is a camber issue. Inside and outside edges I've not seen except on mine, but then the MK roundabouts won't help...
-
I've had the inside edge problem on both my cars. But I've also had the outside edges wear quicker than the centre as well on my 2.5 (on the front)
When you say camber issue, you mean its out of setting? Would a full 4 wheel allignment (I forget the exact term) sort this out?

A full geometry is what I would recommend.

+1 :y
amazing difference when I had mine done...complete with a free final check and adjust after 2000miles from initial settings.
Tony certainly knows his stuff :)

Possibly the sidewalls are weak and letting the crown of the tyre lift in the centre.
What tyres do you have and how old and how many miles?

Dunlop SP9000 235/45ZR17 all round. This wear pattern only on front. I suspect it may be related to working in MK - roundabout city... ...and I'm normally in a hurry ::)
-
I need to get my full geometry done. I think it is more my problem than the wishbones. But my shocks are bad, so need to do those first. Need to get the wishbones checked, because no point doing the tracking if those need to be replaced. So, I need to do the alignment, but it isn't going to happen soon. Meanwhile the steering is too light and it tramlines, consistent with too much camber, which it definitely has. >:(
Much better since MDTM tightened up the steering box tho'! :y

Someone mentioned estate pressures are different again, any guides for the 2.5 V6 Estate (CDX)
