I personally run 35 in front and 32 in rear.  This is a result of 1 yr of pressure fiddling...

do you not get any uneven wear @ 35?
I'm actually getting the opposite of what you would expect - edges wearing...

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
