def task_func(hex_str, salt_size):
    """
    Converts a hex string to bytes, salts it with a random value of specified size, and computes its SHA256 hash.
    The function generates a random salt of the specified size, appends it to the byte representation of the hex string,
    and then computes the SHA256 hash of the salted data. The salt and hash are returned as a tuple.

    Parameters:
        hex_str (str): The hex string to be hashed.
        salt_size (int): The size of the salt in bytes to generate.

    Returns:
        tuple: A tuple containing the base64-encoded salt and the SHA256 hash.

    Requirements:
    - base64
    - binascii
    - os
    - hashlib

    Examples:
    >>> result = task_func("F3BE8080", 16)
    >>> isinstance(result, tuple) and len(result) == 2
    True
    >>> isinstance(result[0], str) and isinstance(result[1], str)
    True

Converts a hex string to bytes, salts it with a random value of specified size, and computes its SHA256 hash. The function generates a random salt of the specified size, appends it to the byte representation of the hex string, and then computes the SHA256 hash of the salted data. The salt and hash are returned as a tuple.
The function should output with:
    tuple: A tuple containing the base64-encoded salt and the SHA256 hash.
You should write self-contained code starting with:
