T-59 Tracks

Can anyone confirm what type of tracks the T-55 series used? Were they steel or rubber? I’ve got Hobby Craft’s Iraqi T-59 and am curious as to which way I should go on this. The few reference photos I’ve seen on the 'net aren’t very convincing, so I bring my dilemma to you.

I have seen a few in person (at Fort Knox) and they were all steel track. HTH

Thanks kaleu, that’s what I figured they would be knowing the Soviet tendency in that direction. Much appreciated!
