I used a black Wheelskins cover on my MGB but I couldn't find a size that really fit it right (maybe it's just me, I don't know). The wheel originally had one of those thick, cheap vinyl covers with the cooling holes in it - the kind you find at the autoparts stores and gas stations /ubbthreads/images/graemlins/rolleyes.gif Anyhow, I left that cover on and put leather over top of it, the result is a thicker wheel with some cushion to it (but not much). I didn't think I'd like it but it really worked out well, fortunately.
