Hi F6, I do work for a client with one of the last D40's. He runs 285/65/18 with a 50mm lift, I think it has sagged a bit. He never has had rubbing but the car only is used around town and never offroad. The test would be full lock with everything flexed. I've not seen anyone with that tyre size here or on the UK site fitted to a D23. But you "may" be ok.
