Castor issues

Hi guys, Currently have a D2 on a 4" Lift with 3° Adrenaline 4x4 castor correction radius arms, however I've recently fitted some 285/75/16 Toyo MT tyres and now seem to be rubbing on the rock slider on the O/S/F !
N/S/F has plenty of clearance and doesn't scrub atall ! Wondering if anyone can shed any light on a possible cause or what / where to check to see if anything is bent ! Also recently fitted an Adjustable Panhard rod hoping this would help the issue, unfortunately it didn't !
Thanks

Have you got the correct length adjustable length panhard rod ?
If not, the axle will be pulled to one side.
There are 2 production rods with quite a significant difference in length between them.
When the rod length was changed the axle mounting position was changed to suit.
Is your adjustable rod suitable to replace both production rods or just one ?
PS With a 4 inch lift your axle will be pulled to the right if you're RHD - which would move the tyre outwards more & probably reduce clearance with the rock slider on the right side.
I've got 235 /85 x 16s and the clearances aren't large. 285/75s are another inch larger in diameter, reducing clearance by another 1/2 inch and your wheel offsets look huge too, also not helping theeffect on lock.
Did you change the wheels at the same time as the tyres ?
Have both changes made an OK, but possibility offset axle much worse
