I'm quite fond of all but one aspect of the ES100s... Non-destructive belt separation that causes a high pitched whine at about 9,000 miles. They lose a lot of longitudinal grip and some turn-in grip with wear, but that's to be expected.
I'm going to give the Parada Spec II's a shot this time around, hoping that the more solid inner tread design will exhibit less shearing force on the belts. Treadwear is marginally higher per Yokohama as compared to the ES100. However, I'll expect more noise overall with the semi-solid inner tread pattern.
The T1-S's I've driven on are notably "squishy" on turn-in, and that's not something I usually notice. Please note: I've not done many miles in T1-S equipped Miatas - mostly other (heavier) cars.
