The wheels I'm guessing are after markets. Do you have hub centric rings? Usually after markets have a different bore size and require rings to fit snugly on the hub
the camry , ive had 19x8.5 et38 others have had 19x8 et40 to et 45 but for 19inch the common width is 8 to 9 inches wide edit : recommended tyre specs are 245 - 35 - 19
I have also read from somewhere (which I shall try and find) that an aftermarket sunroof weakens the structure unless it was factory made. To think about it why didn't you put the extra money in the first place?
