Just thought the law might have changed or something. Mines a 2001.If it was a legal requirement to have one all cars would have been sold with them.
Only for MoT or if you use it. I used to find it odd that a spare tyre below minimum tread would cause an MoT fail though removing said spare prior to the MoT would allow a pass.I think the only "requirement" is that if you have a spare it must be legal.
