215/40/R17 to 215/45/17?

It actually became for accurate with the new size. Closer to gps speed. Especially on highway speeds its spot on.

Which size is that?

Anyone tried 235/40/17?

It's higher than 215/40/17 but lower than 215/45/17 which are reported here as non-rubbing.

The question is the width of 235?

I'm preparing my 2016 Cupra for a trackday car so I need to decide what tire size to get and I'm obviously trying to get more stability hence the 235 in my mind.

Any thoughts?
