Why are tonga drivers seen to pour water over wooden wheels in summer?

The iron rims mounted on wooden wheel expand in summer due to heat.  There is a possibility that iron rim may expand to such an extent that they may slip from wooden wheel.  To prevent such a slippage, cold water is poured over the wheels which does not allow the rims to expand.
