In answer to the question about what tyres are being used. I have now had my 2014 Hybrid for just under a month. It’s great I am very please but have put on it Continental Conti Premium 2. As I have on previous 2 Jazz’s. they grip well in the wet and dry. I have had and tried in the past on the Jazz the Michelin, Dunlop, Maxxis and other I can’t recall, but alway go back. All the others have slipped or stepped out under pressure or load like in the wet or an mountains (Pyrenees, Alps and Carpathian). Just did a 2400 miles trip around France and Spain just after I got this Hybrid, didn't slip and have had over 115 (2 x GPS’s, car indicated different and higher). I say Continental. I tried other Continental models but the were no better than other makes, it has to be the conti premium 2.
