81-258 Metal Wheel or Double Wheel

A quick learner from CALIFORNIA says:
I have the same roller and it needs replacement. It supports a 60inch x 82inch single pane glass door on metal/aluminum tracks. I have 2 of these rollers at the corners of the bottom and two more at the top corners. I was interest in getting metal wheels or maybe a double wheel replacement to make it easier to open. Thoughts? Options? Otherwise I suppose I'd just buy 4 of these 81-258 because they are identical matchs.

Greetings. The roller assembly looks like Ador HiLite Series 1200, 81-258 with a 1-1/2" nylon wheel. We do carry it with a steel wheel - 81-258S, but we don't have it with as a tandem.
