18.5" wheels

[Gothydude]

Hi , Ive bought some rather nice BIG wheels asured they will fit and indeed did come off of an E30. I would like to know what tyre size would be best to fit them. They are 18.5" !! My motors a 18i touring

To keep the rolling diameter the same, you need 205/35R18. I've never heard of 18.5's though, and finding any tyre in that size is going to be tough.

Why would you want your car to look like a pushbike anyway?

Thats huge dude. Your wheels I mean...


And yeah, keep the profile as low as you can go.

Are you sure they are 18.5? Very odd number to have, not seen any before.

Lol my bad guys there stamped on the back 7Jx17" ...I measured them wrongly accross the wheels oops, any idea what would still be the best size for them ?

205/45/17 or 205/50/17

225s are too wide without arch work and/or stiff suspension

I used 215/40/17 as I found the 45 profile caused rubbing on my drop

I use 215/40 17 tyres and its all gooood on a 60mm drop

I got 205/45/17 on my cab, lowered about 40mm and it seems alright apart from the extreme tyre wear and flames when I drive it... No, its ok to be honest.
