245/45/17 vs 255/40/17

Strut clearance becomes a concern with factory struts. I have no idea what Toni is running.

Many people run 255/45's on stock suspension and wheels. My sig pic is one example.

That tire size seems to be hard to find in a max performance tire. A few regular street tires and all seasons but the pickings are slim.

This tire has a relative soft sidewall and decent traction.
