Get her some red Alloy Gators. They give a similar effect, but will stop her from kurbing the wheels, which you will both be thankful later when she inevitably scrapes them along the gutter.
They are sold at Malz in WA, I'm sure you've got similar stores in SA.
The alloy gator website shows how the kurb can't get to the wheel to damage it. And no disrespect intended. I still kerb mine on occasion. I will be investing in these once they are refurbed.

Thanks can go to Brenton (gmonkey) for showing me these things by the way!
