I have 2001 STI Pro Drive bug eye with Bembro brakes It has 235/35/19 tyres and 19" wheels I'd like to go down a size and fit a bigger tyre I've been told 17" won't fit due to the upgraded brakes so I believe 18" is my only option. Can I go with 235/45/18 ?or is there a better alternative

I was gonna go 33 on front 32 rear

Cheers

I've got 235/35/19 tyres fitted to my 2002 STI What pressure should I be looking at for these ? If anyone can point me in the direction of a set of gold 17" id be very grateful
