Well I bought this car to save $! So I'll prolly just stick to 15 or go 16s. If I was big ballin I'd get 17s for sure, however I'm not :\

 

It's not fundamentally caused by the size, but rather the situation of the wide & low-profile sizes (17, 18, 19) are typically available in high$$ performance$$$$ tire types. The inexpensive "standard touring 4-season" tires are usually not made available in /45 or /40 series tires or lower.
