yeah i know that civics are 4x100 and figured that the 4h meant 4 hole and 5h meant 5 hole, also figured that the 6.5 and 7.0 are the width of the wheel, but did not think of the offset which is +40. So these sizes are standard ok sizes for a civic? offset is how flush or far out the wheel would sit? how would a +40 offset sit on a civic? a '91. thanks for your input.
