Yes, exactly - both the main gear and the nose gear have blocky tires.
EDIT
I’ve been busy with various things and didn’t notice that there was an update on February 12. I don’t see anything in the changelog about improvements to the tire geometry. I have updated the 738 to the latest version 4.00.022 and MSFS 2024 SU5 beta is just launching now. I’ll get back to you after checking the tire geometry again.
EDIT2
After the update, the main gear tire geometry hasn’t been fixed.
The nose gear tire geometry hasn’t been fixed either.
The wheel rims aren’t perfect either.
It might not have been a big deal back in MSFS 2020, but with MSFS 2024 and the preflight walkaround feature, it’s a real issue.
