We are talking about a belt drive, right!!? As long as you make the tires the same diameter first, then you can do it first. But if you just set them the same PSI, you are just wasting time. Those tires are never the same. Even if you get them from the same lot. If you adjust your tensioners and rods the way the manual tells you, you can adjust the tracking using the tires, without a gauge or tape.
It's never failed me and can be done in a matter of minutes.
