i have some raze r74's and the size is 17x7 - 205/40R17. my friend has a 06 tiburon and he wanted to get them from me. and the wheel size for the tibby is 17x7 215/45-17. i dont really understand all of these numbers so would someone help me out? i was told putting on wheels with a different measurment thing will kinda mess it up? like driving at high speeds your steering wheeel shakes and stuff.

help please. =]
