We want to change our stock 16" wheels ('04 PT LE) to 15" wheels, and go with tires that have a "medium size" whitewall (around 1/2"-3/4"). I'm not having any luck finding tires with the regular whitewall that will fit. We don't want the big whites, just the medium-sized as stated above. The Michelin Symmetry is about the only tire I've seen, but it only comes in 205/70-15, and may through the speedo off. Can I change the speedo gear? Any other tire choices out there? Thanks.
