I have a 2006 Boxster S with 18 in wheels. Currently, I am using stock Michelin Pilot Spost PS2's (235/40-18 on Front and 265/40-18 Rear) with Porsche 5mm spacers all around. I will probably need tires soon and saw several great reviews on the new Michelin Super Sport tires. Michelin only offers the Super Sport in 245/40-18 for the fronts. Will I have any trouble using 10mm wider tires on the front? Will there be any rubbing on tight turns? I don't want to spend all that money and have tire damage. Any thoughts?
