I managed nearly 30 k on my NG Aero Turbo4. GY F1...
Then last March I installed 18” Carves with good year 4 seasons, with 2 F1s close to the limit being taken off my 19”Turbines so that a pair could be repainted. Then we had lockdown... car done less than 2000 miles since....19” wheels still stuck in mum’s garage...
Slightly softer ride, wince less when parking along a kerb, no significant handling penalty
