What am i looking for with offset? I have the stock wheels now with new Continental DWS06 in 245/45/19.....got pretty bad curb rash on 3 of the wheels, had them balanced 3 times once road force.....still have a bad shimmy from the front end around 80. If i put the rears on the front it is much less so assuming its the rims. Anyhow looking for a new set of rims probably 19 x 8.5 but I dont understand the offset. What should I be looking for?
