To be fair the Kumho KU37 is actually a decent tyre. After a bit of disbelief on my part but assurances that a lot of the guys on the M3Cutters forum rated them highly I threw a set of 4 on my A4 (thanks to a pothole incident ). Certainly a budget tyre that was a chunk less than the T1R's I had fitted before yet they have performed very well and even surprised me at just how grippy they were at Bedford for the odd dry laps and mostly monsoon ones.
