Energy Savers are good, but have hard sidewalls, so the ride isn't brilliant, particularly if the Jazz is on 16-inch wheels, and they become noisy at low ambient temperatures. If you want tyres that are good in the summer and can also cope with winter snow and ice, I recommend Goodyear Vector 4 Seasons. Another reader has had excellent experience of these on a Jazz with wear rate the same as summer tyres. Primacy HP have now been replaced by Primacy 3.
