18" below 1k pun ada... but not PS2 or CSC3 lor...
If not mistaken, they start from 650 or 700, reliable brands such as Falken, Silverstone, etc... at least they're not cap 'palang' or cap 'ayam'.
Some say they're noisy la, slippery la, I can't confirm for sure as I never tried them.
Tyres are expensive, so I don't think one person can give you a good comparison over multiple different brands... nobody changes tyres like changing underwear la bro!
By the way, it's the only contact between your car and the road... remember that especially if you plan to push the car hard... then decide which rubber you want to wrap your new set of 18" wheels with!!!
Good Luck!! Follow you instincts!!
