I’m desparate to get hold of some snow chains to put on the vans we are using to transport people to the AIC/Snowcraft courses, weekends 13-15 July and 27-29 July. The chains need to fit tyres that are radius 185/14. If you have chains we can borrow or know where I can hire them could you please let me know asap. (The Whakapapa skifield hire people will be asleep when we arrive).Thanks.
