While the Aluminum Liger Trailer Wheel # LH39FR does not carry a maximum pressure rating the included valve stem is rated for 110psi. You will need to ensure that this is not lower than the maximum pressure rating for the tire you intend to use.

I confirmed with my technical contact at Grand Design that this is permissible and that other owners have done the same.
