Can anybody please tell me the correct wheel stud size on a late model FL2?

I have recently realised that the socket on the extending wheel brace I've been carrying around for the past 3 years doesn't actually fit the wheel stud.

I've looked on here and on the internet which suggests it's 22mm. The local car accesory shop says it's more likely to be 21mm but unfortunately I didn't have the car with me to try. driving on the right side

A 21 mm socket fits my wheel nuts. Its a 2008 HSE. Don't know if they changed size with the later models.

Thanks Rasmus  driving on the right side

21 mm on a 3/4" drive to make life easier!

That looks like serious kit for serious journeys when you don't expect roadside assistance to turn up anytime soon

21mm socket now in the boot and hope I never have to use it. driving on the right side
