So since the Potenzas suck i want better tires. I may be able to trade my tires to my boy who is gettin rid of his car. Ill get his tires for free. Only thing is theyre 215/40 17 tC i believe is 215/45. So will it work or will my speedometer be out of whack or something.

It will fit fine. The /40 means aspect ratio of the sidewall or percentage of the tread width the tire height is. In other words with a 215/45 your sidewall is 96.75mm or 3.8"and with a 215/40 your sidewall will be 86mm or 3.4".
Should not have a dramatic effect on your speedo if any at all. Not all tire manufacturers measure the same anyways so its not always exact.

I went to one of those online tire calculators and it said there would be a 3.4 percent change in diameter. it also said that staying safe means staying within 3 percent and that goin anymore percent can cause brake failure. Is it really that serious or should I do it. Remeber there is no goin back cause once we trade, his car with my tires is gone.
