The dimensions of the Minispare wheel are 
different from those of the road wheels. As 
a result, the vehicle handling characteristics 
change when driving with a Minispare wheel 
mounted.
The Minispare wheel should only be used 
temporarily, and should be replaced with a 
regular road wheel as quickly as possible.
