Took the opportunity to replace the wheels/RF tyres with a set of used 19" wheels with non RFT bought recently, re-initialised the Flat Tyre Monitor and all is fine. Should have done it long time ago, the ride/handling is much much better, no more bouncing around. Even with 19" instead of 18" wheels/tyres, and cos you can still feel the poor quality of our roads but it is never harsh and much more comfortable.
Inspected the tyres and found a couple of small nails on one tyre, not sure if they are the reason of the puncture warning, again, tyre pressure seems OK.
