The limitation is probably to prevent damaging the rims.
The larger the tire, the greater the outward force on the rim, at the same pressure.

I was once running some 2" tires that advertised a 65psi max on the sidewall.
After breaking the second perfectly good Mavic rim, I realized that was simply too much for the rims, and settled on lower pressures.
