So...ordered some Avon Trailrider tyres and Metzeler Tourance tyres (£10 cheaper) turns up...
Best bit was having to send them a photo...
Offered £5 for their error (£15 total) - accepted it due to MOT being close - but overall not that impressed as the Trailrider has a larger more supported thread block.
Shopped there quite a bit over the years...will use the likes of Bike Busters and Ghost bikes etc. in future - buyer beware.
