Thanks all :-) will have a play with them and adjust the pressures bit by bit and see how it goes. If that dont work then its tuff sh1te and will have to put up with them for a while as they are only 6 months old.
They seemed to work well with the 17's to be honest and really rated them but on 16's im not too sure.
Kenny, i had the chance to get some Advan RC II lightweight racing wheels and swap for my 17's which were very heavy. I have used 15, 16 and 17" alloys now and have found in my opinion that the car seems to prefer 16". 172 does look 8) but would rather work better than look better if you know what i mean
