I just started using these, was rm170 for 215/55/R17. But now only 1k km, so not much complain, noise comparable to worn out Goodyear Efficient Grip.. Grip on dry/wet so far ok, but braking distance somehow feels higher..

Also not sure if my car issue, but sometimes at high speed it has a tendency to sway left/right abit, but nothing serious la, still can manage..
I suspect sidewall is not strong, so hence the swaying and increased braking distance.
