245 / 40 / 18 tyres ok or will they rub

[M/bikertom]

As title, I have a set of 18" RS6 alloys from my Audi A6 that'like fit my new caddy though as most people seem to be using 225 / 40 / 18's.

Has anyone had problems with this size tyre on either front rear or both as they are fairly new tyres.

Thanks in advance

It all depends on offset, 245 is a bit wide, 235 is as big as I would go on 18's

I fitted A4 wheels to my caddy with 245/40/18 tyres and an et 47.
Standard suspension and no weight in and had no rubbing.
Rears were really close to inner arch at rear edges but will definitely rub if lowering.
I changed them straight away as the main problem was they over geared the van too much plus I was lowering van.
