Had 4 Goodyear EfficientGrip Performance tyres fitted to my LCR on Thurs.
The 'Performance' moniker denotes a new version for 2013, which is officially A-rated for wet grip, B for fuel efficiency and 69dB.
When handling the tyres during fitting, compared to my old Falkens, the Goodyears felt much lighter, which is good for unsprung weight.
First impressions: the side-walls feel nice 'n' solid, no sense of 'squirm', dry turn-in grip is very impressive, feel very consistent through fast/flowing corners and stability during heavy/late braking is particularly good
And while driving on local A-/B-roads, V-Power consumption has improved by approx 4mpg
Smug, moi?
