I have just replaced the steer tires with 12R22.5 XZ2

We have a flat on the right outside drive and want to replace all the drive and tag tires (it is time)

Currently they have 12R22.5 XZA on them.

I am being told that both these tires are discontinued and not available here in Canada.

What tire should I put on the drive and tag? I would like to keep them all the same brand if possible.

I can have the tire plugged today and drive it to a dealer in Calgary or Edmonton later this week.
