Tyres for Ace Award

jillybetts

We had a blow out on our caravan on the M6 this Tuesday. We were very grateful for the recovery crew that came out as we were just on some roadworks. 

However, we have put the caravan back on storage and in our wisdom left the tyre in the front box! We need to find out what tyres are needed on the Ace Award Nightstar 2003, so I can organise for a mobile tyre company to come out. (As we want both tyres
replacing so they are the same). 

Could anyone help me finding out what tyres I need 

e.g. the numbers on the side - 175/40/r17 etc.
