Thanks for the reply. I am with you on the offset calculation. It's my annotation that was probably confusing. The wheel comes in a +25 and I would add a 10mm (maybe 15mm) spacer to bring it to +15 (+10 if I go 15mm).

What would have to change to make the 285 turn in and not wander? Some increased caster and toe out in the front seem like the theoretical answer. Is that what you are thinking here? I would be open to any option that didn't leave me replacing a tire that has 8/32 on the outer edge and 0/32 on the inner. In other words a bit of inner wear would be acceptable in my book.

Note: I am stuck on 285 due to the Michelin sizes. The next option down is the 265/35. Would that be better or would it create an imbalance in the car's handling; primarily thinking about understeer.
