Help! calling Silvercross Pioneer / wayfarer owners!

[Seasidedolly]

I may be being completely thick but how do I remove the back wheels from the Pioneer?!
It just arrived today and I'm trying to get it back in the box after having a little play, but need to remove the rear wheels else it's too wide to fit. I can see the front wheels have red release buttons but can't work out for the life of me how to get the rear ones off!

Thanks :)

I'm not 100% because my pioneer is packed away until baby arrives in April but I think you need to use a screwdriver or something that shape to push a button in and then wheel slides off.

Oh really? :s I thought the back wheels just popped off like the front ones! Lucky we've got a bigger car on the way!! Thank you for your help
