I needed your opinions on a little issue I ran into. I want to put 225/45 size tires on my stock TL-S rims. From what I was told, if I put that size (225/45) it can actually cause the speedometer to read incorrectly. What they mean by that is the speedometer will be off by 1 - 2 mph. Another issue is that I can not have my tires be wider than my rim. It may effect my handling and cornering. Are these true? Your opinions are greatly appreciated! Thanks

 

If I were you, I would run 235-45-17. Its close to stock tires in diameter. Stock is 25.6,235-45-17 is 25.4 and 225-45-17 is 24.9. It will definitely throw you speedometer off by few miles. Original speedometer is alreay off you 2 miles.
