i took mine out and replaced it with a first aid kit, warning triangle, jumper leads, fire extingusher etc etc etc all the goodies
i find it quite funny now though that i will have all of this but wont be able to get home with a flat i might find some time this weekend to shoe horn all of it in with the spare included.
somethign worth noting is that the spare holds your boot floor up, withough it it all caves in when you put a back of heavy stuff in it. like a punch bag,
