how silly question I am asking, I overlooked the R17 at the back
I think tyre shops will give advise to you also that 205/40 is kinda dangerous to use here because too thin. But what you can do it get adjustable suspensions and get yourself 205/45 or 215/45
If I not mistaken, 205/40 is kinda rare. So far I only tried Hankook Ventus V12 205/40 but too low, so changed to 205/45
rm 300 per piece for 40 series not much choice for good branded tyres like falken,toyo,yoko,bridgestone,michelin n etc... branded tyres will cost about 380-700 for 40series 17"/18"
you can only get cheaper brands like maxxis, accela, nankang,sime.. hankook im not sure can get or not...
