Whilst putting new disks and pads on the front today i noticed the rear tyres need replacing very soon, But on the front they are 185 55 15 and on the rear they are 205 50 15, The fronts are like new, but would you put 205's back on or match the rears to the front with 185's
What would you suggest is the correct thing to do

Those sizes are correct for 15" wheels. Bigger at the back.
