Finally measured the rear tyre tread on the Panda yesterday and they were 1.1mm, well apart from the inside edges which were slick
Couldn't find anything cheaper than £50 a corner on the Interweb Thingy so on the way back from Birmingham this afternoon called into Supertyres in Luton
Negotiated four Marshall 175-65 R14's for £40 each and lazer steering tracking for £20, total cost all in with valves, balancing, tracking and disposal ( a lot of companies add £10/£15 per tyre for disposal ) was £180
I'm lot happier with a good set of tyres now that winter is coming
