235/55 R17's, much easier tire to find.

400 Treadwear, A Traction, A Temperature

They are. They're amazing for the money, they're considered "performance luxury all seasons", plus Toyo is a high quality brand.

My shop sells them if you want to order a set of tires, they'll ship them to you.

tire guys said if i get "55" instead of a "60" it will throw of my speedometer, is this true?

Potentially. I know the speedometer on the Phoenix shows 5MPH faster than actual (Ex. 50MPH is actually 45MPH) because I have 14in rims and not stock 15in the tires are respectively smaller than stock. Since smaller wheels spin at a higher RPM, if your speedometer isn't adjusted accordingly it will think you are going faster than you actually are.

And the opposite will happen if you go bigger than the stock size.

DERP, re-read the first post.

Yes, the smaller height and overall diameter will spin faster, throwing off the speedo.

There's no advantage to running a smaller diameter than stock, stick with the stock tire size.
