Looking for spare wheel

[colin cohen]

I have a full size spare for my Sport Q, but would like to have the
alternative of using the trunk on a road trip (such as to WG for the
Nationals) as this wheel is a massive 15 X 9.  I have searched the web to
see if there is anyone who sells those awful (but useful) mini spares, but
without success.  I know the overall diameter I am trying to attain, and the
wheel bolt pattern is the Urq 112*5...so if I could find a supplier I should
be able to engineer a fit?

Any ideas out there?
