You're looking at somewhere north of 4K USD for a set of PSE 17's polished, including the tires. If you want to run 335's the Michelin Pilots are a good choice, but there are others. Do some shopping. I bought my PSE's in 2004 and paid 2400 USD. The difference in width between 315's and 335's is 20mm. Go to Tire Rack and check individual manufacturers specs to get actual widths, i.e., tire patch. When you order the PSE's just tell them they are for a SPF and they will send the correct width and back spacing. Additionally, SPF now offers 17" wheels direct from the factory as an option. I've seen a set and they look terrific and I think you'll find they are less expensive than the PSE's because you can order them as an upgrade.
I'm running 275/40/17 in front and 315/35/17 in the rear.
