Why are TRD fake beadlock rims 7.5 wide?

So,

As the title says I was wondering if anyone know why the fake beadlock wheels were 7.5'' wide. Also correct me if I'm wrong but those wheels are made by BBS. Was that just what was available or did TRD do some testing and decided 7.5 was the magic number?

Thanks for your time. Cheers.

 

Because they weren't going to put giant tires on a factory truck.

 

Considering the max you would want for airing down would be 8”, and a narrower wheel does a better job at holding the bead than a wider one, 7.5” is an excellent size. Not sure what you are expecting.

 

Honestly I was hoping for something prolific. But I guess I will just keep looking for a used set of the same wheels you have. I just can't justify buying a new set of them.
