Anyway, folks,
I went ahead replacing my Yokohama V552 with the Goodyear Assurance ComfortTred after much ding dong for almost 2 weeks. (205/55/R16).
The DOT is 1724. About 7 months old! So, a matured new tyre! Just the right time!
The workshop pumped 250kpa for all 4 tyres as the usual practice and OMG! Even at that high kpa. This new tyre really gives such a quiet roll, low vibration and super nice soft and gentle bumps over uneven surface and road bumps and over those metal bumps.
The Goodyear Assurance ComflrtTred is definitely way better than the V552 in all departments.
The V552 is super quiet but it wasn't that soft over bumps. At the 250kpa, the V552 would produce super super bumpy ride but not the Goodyear Assurance ComfortTred.
The differences are so much and so obvious.
I think I have made the right choice.
