Tour buses go through the Zion tunnel every day. However, I've been through the tunnel on my Harley and I found that I wouldn't want to take my rig into the park. I'd park it somewhere outside the park, unhitch, and take the truck in. The roads can be tight and crowded with tourists. Zion isn't really big-rig friendly.
Get yourself a Motor Carrier's Atlas at any truckstop and use it see if your route is OK for the truckers.
What I would do if you are going west into the Zion tunnel is you and your wife slide over close close to the drivers door and lean to the left until you get all the tough. Remember lean to the left.
