I've seen those leather covering kits for steering wheels..looks like a pain
to install, though it IS nice not to have to hang onto the thin plastic rim
of a steering wheel for as many hours as we sit behind them in our vans.
  What I have done in the past for other vehicles with plastic steering
wheels is to use handlebar wrap from a bike shop/catalog.  Works really well
and it's pretty easy to do and get a pro looking job that feels great on
your hands..
  Look around and you can find just about every type (color, texture,
material) of wrap from real gen-u-whine leather to gel-filled (for you Tiico
owners) vibration absorbing whoop de do stuff.  Cheap, easy to clean or
replace and feels good in the fing-ies..Especially with winter coming on..
