I'm trying to buy aftermarket wheels in what is apparently an off size that might not even exist but I'm trying to avoid wheel spacers to get tires to fit can you help? I'm looking for 17X10 but I need at least a -.44 offset I think.

 

Why is it you think you need a -44 offset for the tires to fit? Negative offset pushes them further out and will reduce your chances of fittin bigger sizes
