This would appear to be true, however I believe a year ago they only gave four stars to the XR the same for the regular marathon. Though I could be mistaken.

Still, giving four stars out of five to a tyre that punctures every few hundred km, and falls to bits is a bit misleading in my opinion. I would have used the marathon plus, or continentals if they had been more honest with their rating system, or pointed out that the tyres were worse than their old 308's (which they do recommend only for city use).
