[osbourne one-nil]

I'm returning my leased XC60 in the next few weeks and have read the terms and conditions about tyres - the ones on mine have a min of 3mm tread across the rear (which is pretty good as they've done nearly 65000 miles) and a min of 5mm across the front. Last time it was in for a service the dealer commented on uneven tyre wear, but I can't see evidence of this. Does anyone know how fussy lease companies are on tyres? Will "legal" do? I'd obviously prefer not to have to fork out several hundred pounds on replacing them.

They're Nokian Weatherproof btw - I can't think that that would cause an issue would it? I think their ratings for economy and noise at least match those of the Pirellis it came with.
