My Ti wheel bolts are anodised. I was told that this keeps them from galling. I have taken them on and off 5 or 6 times and each time torqued them to 85lb ft., they show no galling and look pretty much new. A tiny bit of color change on the engaged threads and the cone(to be expected for any material, steel included). Ferrari uses titanium for wheel bolts on quite a few of their models. I have not heard of any problems. Porsche still uses aluminum wheel nuts on some of their cars.
