I am currently using 2 fleva on my Subaru forester. I probably concur with the test. on marginally wet road (after rain) and taking a 70-80 degree turn at about 60km/h (it's a wide road).........car was understeer.....when I try to correct it by increasing steer, car start to fish tail.....as the tire lose grip.

on other occasion, when road is dry, taking a similar turn at about more or less the same speed, I do hear some screeching sound (not a long one , but an audible one).

not looking like I will buy another 2 piece to replace my 2 older tires.
