Hi ive got a 2003 st170 with 18" wheels fitted to it but ive got problems with the front wheels hitting the arch sometimes the suspension looks factory / standard so i dont think its lowerd whats the best size tire to use with 18" on a focus st170 ?

i may put a post on swapshop as id like a set of standard st170 wheels really the wheels are 18" BK333 Black they do look nice on the silver car but the catching is really annoying me so thought id put a post up and check the tire size out first

You need 215/35/18 tyres.

ahh that clears it up a bit i think there bigger will check the size thats on it later cheers

Delta-Force

Well the tires that are fitted are 225/40/zr18 so thats why there rubbing then . . another bill to my list then when ive sorted my engine prob out on my other thread thanks for the reply i will make note of the size cheers

All depends on the offset of the wheel as well. The FRS runs 225/40 18 tyres as standard.

Delta-Force

yeah thats woth looking into as well ,

il whip the wheel off asap and have a look what the offset is too they dont catch much just now and then but its annoying me when it does lol

thebigmacmoomin

Yeah it does but the Focus RS has bigger arches

well bit of an update the problem should be sorted tomorrow ive just bought a set of 17" wheels tsw freeze 205/40/17 so i can sell the 18" bk333 that are on it hopefully no more rubbing then im going to replace my plastic inner arches as mine are quite worn now after 18s being on it with 225/40/18 tyres i decided not to risk new smaller tyres on the 18's incase it still rubbed the 17's was at good money with 1000 mile old tyres and ive also got a pair of brand new toyo proxies in the garage to fit 17" for spares



so hopefully tomorrow no more rubbing
