just changed all for from yoko fleva v701 at 30% thread remaining. Didn't intend to go for this model at first rather looking at P1 or P7 but both of those models don't come in 215/50/17 size. So i guessed Powergy would still be ok and the promo price kinda sealed the deal.

To my surprise it turned up the noise several notches up during during my recent 500km up north. especially on the concrete paved stretch on PLUS highway. and the steering felt unusually light during slow speed a bit unstable at high speed

Found that the pressure in front passenger side was wrong. at 285 kpa, was way too high so i reduced it to normal level but it didn't change the behavior that much. still very much rumbling from the back. even my wife noticed that it is noisier than normal, which is saying a lot

Why Pirelli u ask? well, the shop near my house had a big Pirelli signboard and they do good alignment. so i gave it a go

Is it possible to get a refund and change to other model? else i'll be stuck with the noise for a couple of years until it wears a way
