The reason i said they're too narrow is becuase the tyres are stretched inwards, with the wheel rim extremely exposed and the tyre sidewall at a huge angle.
Tyres arent designed to operate in conditions like that, and will not be performing anywhere near their best, not to mention the rim and sidewall being extremely exposed to damage from the pristine roads in this country.
I asked about camber becuase one of the pics looked a bit odd, but i suspect its just the angle its taken at.
In my opinion, modifications should be done with function first and form second. Plenty of people run 18" wheels with tyres that fit correctly so its not impossible to achieve. Theres no point doing something to the car if the car then doesnt work properly afterwards. I could fit some 22" chromes and remove the springs to make it look "pure amazing" but if it then wont drive or i cant steer whats the point...
As geeman pointed out, they're still fitted with the tyres that they came with, so hes not made any active choice to fit those, which is fair enough.
Personally, i'd be looking to try and ditch some of the spacing on the rear, and run a 235 tyre on there, but having not seen the car i dont know how much clearance there is to do that.
