where is the cheapest place to buy a car tyre in mahon

There are many car dealers in Maó. Most of them take cars in part exchange for new ones. I suggest you visit the locations with cars on show and look for something you like, and negotiate a price . I traded my Old Ford with the Toyota dealer.  I think most of the car hire companies sell off the 2 or three year old ex hires. You could also try them. Also you sometimes see ads in the Menorca  newspaper. Rgds
