Yes. Stock 19" sizes are 245/35 and 265/35. Narrower fit (recommended for winter) would be 235/35 and 255/35. More aggressive fitment would be 255/35 and 275/35.
Sounds like you'd benefit from a bit of time reading around the forums. That's how many of us gained CRAZY amounts of knowledge about our cars.
Oh yeah, I'd suggest staying away from the cheap stuff you find on ebay!!! We're talking about your $80k+ car!!!
