If I were to put on some 18 x 7.5 with a 48mm offset, will it look funny on the tC? Will the wheels be pushed in too far? Will I need wheels spacers? If so, what size? Thanx

 

here's a calculator. plug in the standard size then your new size. it will give you an idea of how it will look. (the standard is a 45 mm offset).

18x8.5 with a 48mm offset has been done before and it does not rub. Trust me, you will be fine. You have nothing to worry about. 17x7.5 will give you adequette clearence over suspension and calipers even if you're dropped.
