Autogrip F107 270/40 R20 BMW 500 miles March 20, 2014
I had to have a tyre replaced due to a puncture and this was all the mobile fitter could get. Initially I thought it was fine then I went into a bend in the wet and the car slid sideways and I mounted a bank. I was not going too fast !
This tyre is lethal.
Wear I can't comment on as it lasted 2 weeks before I changed it.
Do yourself a favour and avoid this tyre and there should be a law against this rubbish being sold

Excellent tyre for the money especially in the wet, i'd say probably the best in the price range and better than a lot of premium tyres, highly recommended on my T5, i will be using again and again.
