Widest wheels / Arch work.

[Poko]

Hi all,
I am looking to fit to my car (Pre FL cupra) wider tires.

the size i am interested in is 255X35X18 , fitted over 18X8.5 ET ~45

I know that in the GTi this is possible but marginal , but i have no clue about the Leon.

does anyone know if that will fit (at around 2 degrees camber) ?

as a second option , if i can't make that fit i will consider some arch work or a wide arch body kit (not too aggressive). does anyone know any (experience) ? i have seen the JE wide arch kit but that doesn't fit cupra.

thanks in advance.

I know that the wheels will fit, as I have 8.5 x 18 ET45 for summer use. The tyres are 225/40 R18.

255/35 R18 will have about the same rolling diameter, but may have issues with the arches & will be a firmer ride (less sidewall).

That will seriously affect performance unless you're putting down 300+ power.... is it for looks only?

Only affects performance & economy very slightly.
Hardly noticable.

what, using 255 tyres? I havent tried it personally but I'd be surprised if you couldn't feel the difference even from same size 18" 225 tyres... its 3cm difference!!!

With 255 wide tyres you will!!
I'm using 225 wide tyres, though.

i will be putting down 450+ hp , so no problem with performance , i need the extra traction.

also will be running high camber, so on a straight line it will not be "wider" than 225's.

as for shoulder height , it is around the same as 225/40 - 90mm in 225's compared to 89.25 in 255's.
