I'm using the NMRA gauge and the slot I cut into it that matches all of my wheels sets and it measures 26.5mm. That actural gauge slots are 29mm. I measured everything around the gauge and nothing measures 37mm. The inside track width is only 32mm.

I made a huge mistake by trusting memory. I looked up my notes.
The average I use is 27mm NOT 37mm
Sorry about that. I'll correct my posts.

No biggie. Figured it was a typo. Didn't know how to post it without sounding like a mean grumpy old man.
Whats with the metric dimensions? O scale rail width is 5 feet (not 4’ 8.5”). Thats for both two and three rail except for P48. 1/48 is 1.25” (1 scale foot = .250”). Rather than measure at the tip of the flange, measure where the flange meets the tire. Again works for both 2 and 3 rail.
Menards and now RMT (same trucks, don’t let anyone tell you otherwise) come with wheels way under gauge. I fixed mine like MikeCT does except my bolt has a hole in it so it doesn’t flatten the point.

Easier for pretty much everything. My vernier caliper is metric as well. There are online conversion apps all over the net as well.
Also, some of those pullers will break off the edges of cast metal wheels so spares are necessary.

As do mine but 27 mm equals 1.06299”. Not even close to the correct gauge.

From your photo you are measuring between the outside of the flanges. I measure from the inside. Try that and see what you get.
