Depends what you consider stretch is.
There's people on here who think a 235/40 on a 9.5J wheel is 'Mad stretch yo' which in reality, is barely noticable.
But if you put a 195 on a 9.5J, Then that's where you're running stupid stretch, which the scene kids love. Which indeed boarders the line of Illegal, tyre will pop off, damage, @*!#/dangerous on track.
You've chosen show/scene wheels. These aren't for track in those sizes, unless you get arch extensions. As you're going to have to run stretch for them to work on track without rubbing.
I've got a 275 on an 11J wheel. And I rubbed, I had to raise the rear a little to stop that.
As I said, these aren't track wheels, these will fit, but to make them work on track, they're going to look crap as you will either need to -Run a high ride height to avoid rubbing, - Go silly stretch to have it low and no rubbing, - or spastic camber.
