Yes they are +30. Test fitted and measured at the shop. Keep in mind that each wheel design may vary how far out they go. So a 30+ for one wheel design may not fit exactly like another with the same offset and width.Are these really +30 offset? IF so that would move the outer edge of the wheel 3.15" out away from the hug, plus another 0.5" for the wider wheel.
It doesn't look like those are 3.5"+ farther out. They look more like -30 offset, but I could be wrong....?
