Sounds obvious but as I know nothing I just wanted to make sure............. We have an S-max which does not have a spare, only one of those ridiculous inflation kits. About to go off skiing and dont want to risk it so was thinking about just taking a spare along with me in the boot. We have 18" wheels on it so I take it I will just need another 18" wheel (do you need specific ones for specific cars? - thinking about weight), Have read some people using different sized ones (and adjusting the type profile) but cant imagine that's a great idea, a jack - Draper 39055 4-Tonne Hydraulic Bottle Jack: Amazon.co.uk: Car & Motorbike Looks small but will strong enough - do I need to find one that matches specific model jack points (reminds me, will have to find out where they are) And a nut wrench - I take it you will just be able to attach the locking nut adapters to these for those ones. Anything else??? Have never changed a tyre in my life - any stupid things I need to remember? any recomendations on getting a spare wheel? Oh and sorry - was meant to be in the motoring section.
