Yup they look dodgy, my rears are worn too, but not down too the steel wires showing, last time I drove with a tire like that it blew on me, I have searched high and low and found that toyo proxy st's seem to be a good mid range tire....can't get re-moulds or second hand tires where I am cos the number of cars on the road with the tire size in question is limited....try http://www.tires-easy.com/ they do decent prices I think.
