Can you provide a link to your test file, so others can test with it? Is your file possibly in CMYK color space?

Have you tried

convert FILE.ai -depth 8 FILE.tiff

or

convert FILE.ai FILE.tiff

or

convert FILE.ai -type PaletteMatte FILE.tiff

Note that a ".ai" file is actually a psotscript ".ps" file. As such it is a vector image that needs to be 'drawn' at a specific density.

Update.
We have tried al these methods:
-depth 8 (we want 8 bits)
-transparent #FFFFFFFFF ( because the imagemagick "thinks" that the file has white backgroung
-alpha on, off, set, transparent, shape...
-palleteMatte
-compress LZW
-colorspace
-type TRUECOLOR
-channel RGB
...etc...

What we are trying to achive , is to be able to use a AI file and have it exported, directly into a tiff file having it´s tgransparecy values.

We want to use imagemagic. to be able to make a batch system. and not have to go back into the adobe programs like photoshop etc...this batch is to convert hundred of ai files to tiff

The project is AI to tiff, we want to have a tiff file with LZW compress, 8 bits depth, RGB.

we have tried passing to png or psd and then png to tiff, directly ai to tiff ....and we don´t succes . the issue ve are getting is in the transparent or ALPHA is not working correctly.
We are getting a border in the alpha and in the compo program it shows up and is not working.
we need it be be like this:
