245/40/18 on a Convertible

No issues at all. I'm on standard s line ronal wheels and there the tyres that were on them when I bought them. I have barums on the front and pirelli s on the rear.
What do you want photos off? I'll get some later when I'm with the car. I have a side shot of it.
 
Looks ideal.

I wanted to make sure there were no rubbing issues and being wider it gives a bit more sidewall and comfort.

Looks really nice.
 
Nope no rubbing at all. I've had 4 adults in the car as well with no rubbing issues either, clear the arches fine !

Couple of arch pics


excuse the dirty wheels!
