Using Work Equip 1 wheels as an example. When they machine the mounting flange, they do it two different ways which they refer to as "O" and "A" disk. The "A" has a 10 mm thicker flange area, which gives more caliper clearance but the thicker flange require a longer stud.Alvin wrote:I'm confused. I thought longer studs were required on wheels with low offset or wider than stock width.
What does the metal insert have to do with it?
I thick there are more offsets available than there are casting, so some have a thicker flange.
My 15x7 +12 Retro 4 have a very thick flange (lots of caliper clearance), but require longer studs.
They offer +18 and +12 wheels 15x7 wheels.....the +18 wheels may just have a 6mm thinner flange on the same casting.
My wheels have a metal insert for the lug nuts to seat against. They have a "shank" portion that help hold it in place that goes almost completely through the flange. They may have different inserts for different offsets or they might machine the flange after the inserts are installed.
My inserts would be machined if It took more than 3 mm off the flange.
