I've seen several mentions about tires ~45mm, I'll add some of my own experiments:
I'm a fan of 2x AXS and I managed to bypass the limitations of the non-wide front derailleur (42c max) and install a Speedero 44 in the rear (45.5mm with 24 hook inn).
The Airwolf frame itself is indeed similar to Aspero in terms of tire clearance - I got acceptable gaps of 4mm in the chainstays.
As for the front AXS derailleur - I managed to get a +2mm tire clearance extension in the battery area (3.5mm in total) by making a spacer for the front derailleur mount, and derailleur frame remained within adjustment tolerances for the combination with non-wide Red + 43-30 rings.
