Cannot find correct size tyres
Pardon my spelling I'm located in Australia so thats why there's a Y in tyres. Anyways I'm wanting to replace my tires as they are cheap and old and one isn't holding the right pressure for long. The placard on the door says I need 215/50r16 89v tires to suit the (original) rims it comes with. Currently the car has 225/50r16 96w tires fitted, which do rub the fenders a bit when I lock the wheel. I thought this was odd, until I looked for the correct tyres on the internet and could not find them anywhere. I'm thinking this might be the reason these wider tyres were fitted. Just curious if it would be fine to replace the tyres with the same size fitted or if I should look further into finding the perfect fit. For reference, the car is a 2001 Ford/Mercury Cougar. Thanks for any help, I'm new to this.
