I never read anything good about PS31. Better try that new D06 or Toyo TR1, or even the Prime 3 than PS31.
Prime 3 is actually not true replacement of V12E2. That's just what marketing people want customers to believe. Prime 3 is still a touring tire category,  not UHP like V12E2, even though it might be pretty decent.
That's a pity. This means no real proven UHP below rm180 for 15'. Options now only TR1, V701, RE003, F1D5, PS3, and the new RE004.

Hi, I am using the Dunlop D05 Tyre 195/50/15 manufactured in 44th week 2019 year, for around 2 years with 25,000km. So far, the handling and cornering still good to be control. The noise level still can be acceptable, also depends on the road condition. It may I have shared some pictures which the Tyre seems hardened if no mistaken. Should I replace them immediately or can be wait? The "Sun & Rain indicator" still can be seen clearly, and the thread depth considered ok. Usually, I parked at open air residence roadside, therefore the rubber seems aging faster, because I drive around 15km - 20km per day.

If do so, I will consider changing Dunlop D06 Tyre as I am satisfied with its predecessor D05 wet & handling performance, especially cornering. The price I survey in Melaka costs around RM185 - RM205 per pc, including balancing, alignment and rubber valves.
