whats up fellas i have an 01' a4 1.8tq, i just ran by an awesome deal on 19" tsw's and i realized the width are a problem not in the front which are a 8.5" width but the rear is 9.5" inches wide, ive been trying to do alot of research and come to the realization that i will have to be using 225 or at most a 235 width of a tire which isnt the problem, the real problem is fitting the rim!!! if i cant use them ill sell them and probably make money but theyre SOOOOO nice and would look great on my car, anyways trying to do research on what means what as far as "offset" and "et" if theyre the same or different thats how far my knowledge goes sorry real newb here.....anyways they are a 20 offset and hopefully thats a good thing? any help would be great guys and thanks in advance..
