Thanks all for your participation in this life matter discussion. Hahaha.

I forgot to mention, tires replaced since 2016.

Ya lo. According to the indicator still Ok. But if according to the year? Should change?

Agree, if got budget better replace (if) haha.

Updated info: I replaced on mid of 2017. As your view, how long should a Tyre last (good to use) before replacement?
** I shall specific that I'm an Outstation and highway driver 😂
Aiya, forgot already.let me check check ya. Should be mid of 2016.

Another consideration is the tires condition. According to the replacement date, tires were 2yr+8months old since on the road. Still, although still hasn't reached the indicator mark, but tread seems faded? Some rubber on surface was peeled off 😅
