Winda WP15 165/45 R17 Ford Fiesta 5,000 miles May 8, 2017
Were the tyres on the second hand '03 fiesta that my partner bought. Can't compare traction of the car on these tyres compared to any other as I've never driven a fiesta before nor have I driven on Winda tyres before.

Had the car for two years and has been driven roughly 15k miles in that time. Tyre seem to have worn excessively in that time compared to other tyres on other cars.

Had a blowout on a hot day, tyre completely melted. Had to leave it at the side of the road as it was smouldering.

Would recommend spending the few extra Euro and getting a branded tyre.
