If I was going to get 17s with a 45 tire I was told by ALOT of people that the bigger wheel size could throw off my speedo by like 10mph. And also for next winter I plan to get a winter tire with a 15 rim (195/65R15) and i do not want the 17s or 15s to throw off the speedo (right now are the factory 16s)?????????
if you get a 17 inch wheels and put 225/45/17 rubber on them, it will NOT throw off your speedo. the overall diameter of the wheel/tire combo will be the same as stock. just a side note, i wouldnt take any advice from any of those people again.
this is my sig
Read the FAQ at the top of the Wheel and Tire Forum list of topics. It should answer all your questions on wheel/tire sizes.

What he said.
If you were running a smaller tire size like a 205/40R17, then yes. I know from personal experience. Also, running that small could also effect your gas mileage as well.
