You can get one on ebay, cheapest is 15"

Ebay is good. You can use a size smaller diameter for a spacesaver compared to your road wheels, and a lot thinner, as it can only be used to get you home or to the garage and do not exceed 50MPH. (I would go slower )

Make sure you get a 2 ton capacity jack, as ecosport is quite heavy. A big scissor jack or a hydraulic type will reach.

Also get a long telescopic wrench for the nuts. The one I got from Ford was rubbish, so I got the telescopic one from Halfords (under a tenner).

Hi thank you for the information. I have a 2 ton trolley jack, but bit to clumsy in the boot. Have to look for a scissor jack, is that what you have? Is the nuts 19mm? what wrench did you get, 18mm 0r 19mm the nuts, not sure to be honest. I had a Ford c-max before this eco, think they was 19mm. Presume all the eco's be same size nuts. I feel sure they look like a 19mm. I know what you mean about the tyre wrench, the Ford one's are small. I had one with c max, I got a piece of hollow steel bar to sleeve over it, for longer handle.
Will have a look on ebay for a 15inch space saver. I have a 16 inch space saver for my c max, it a 5 stud wheel, so be no good, as the eco is 4 stud. Thanks.

19mm on my 2016. Assume all years are the same, but you will have to check.

Do you have a socket set? thats an easy way to test that 19mm socket head works.

My telescopic wrench from Halfords can change socket heads. Came with 17mm and 19mm socket heads.
