check with your friends,
possibly they could have a 175/65 r14 or maybe 185/60 or 185/55...
the 185 denotes width in mm, the 65/55/50 denotes the height of the sidewall in percentage of the width.
it could be that ure tyre is too tall and therefore rubs against the inside of the fender. see wat tires your friends have and then take appropriate action.
also, immaculate condition dosent mean that its suspension has never touched the road... if you know what i mean, it depends on your suspension and the height of your car.
