Help!!!

I am currently in Spain with my 1998 Fourtrak and have had a blow out. Ok no problem just change the spare and get another tyre.

WRONG!!

The large tyre dealer I went to says that the tyre is UK they do not have the same sizes.

Can anyone tell me what tyre size I should be looking for in Spain?

The Fourtrak, known as the Rocky over here, should have the same tyre surly??

Please help!!

Thanks
