Ed209, Silverstar and Icon are 16 x 7 with 5.25 BS the way Jeep measures them.
It is possible Jeep's way of measuring BS might be a little different than how other wheel brands measure, which might mean Jeep's 5.25" BS measurement is same as the 5.125" BS you measured.
i.e. - it's possible that a 5.25" BS Jeep wheel is same as a 5.125" BS aftermarket wheel if two slightly different methods of measuring are used.
In any case, the Jeep official BS for Icon and Silverstar is 5.25" BS as Jeep wheels are measured.
