Tire clearance issues with wider rear tire

I have recently increased the rear tire width to 150 and noticed that it now rubs the driveshaft side when riding 2 up. Is there a way to align the rear wheel / axle to increase this clearance slightly? Thinking maybe removing a shim in the driveshaft or similar? Some older bikes used to have an axle adjustment... Thanks.

not sure it's doable? There's a spacer between the diff and wheel that determines the correct distance between the two, If you alter that distance to off set the wheel it'll cause handling problems I'd have thought.
