so far so good no low hum, very smooth, quiet and no vibes to 130kph. Very good road absorption, handling not quite as crisp but cornering very salf-assured. No ware stats yet. Price excellent.
Noticeable great grip on the road I replace 2001 Turanza EL40s with these new G019s. I am most concerned about road noise, and while they do seem quiet and extremely smooth, there does seem to be a pervasive low frequency hum. This could be my overlistening; it could simply be the wind. I notice an exceptional grip on the road; I can sense their racing pedigree. Today, on having to stop suddenly, they did a much quicker job than my aged Turanzas (whose treads were still adequate). The Potenzas corner very well. I am just concerned about the noise, but we will see.
