Questions about factory wheels

Why do factory wheels use a positive offset while most aftermarket wheels use a negative or 0 offset?
On a related note, why are factory wheels not nearly as appealing as aftermarket when aftermarket usually isn't any more expensive? Take for example to 2016 TRD Sport wheels. They are nice and clearly some thought went into the design, but they aren't nearly as nice as the simple Level 8 Mk6's that so many people on here run.
I'd love to hear your thoughts.

 

The factory wheels use a positive offset to keep the wheel under the truck they are designed for. Aftermarket use negative as they are not designed specifically for the Tacoma and push the tires outside of the body.

I consider my factory wheels to be pretty sharp looking:





Note that OEM parts and aftermarket parts are not built to the same standard. Aftermarket parts are always far cheaper. Most aftermarket wheels are built to lower quality standards in China to be competitive with lower prices in the aftermarket space. The average aftermarket buyer is usually interested in looks, short term gain, and getting it cheaper. OEM is about exceptional quality and long term durability. The OEM is going to be concerned with building a light weight wheel to help meet govt mandated fuel economy regulations while maintaining maximum strength and durability through superior design and alloying, while also making a product that can still look like new 10 years later. Aftermarket cares about none of that.

 

Those wheels do look great. I disagree on some points though. For instance, there are some high end after market wheels that improve the performance of a vehicle. Light weight alloys or bead locked, for example.

 

Those are sweet I like my OEM as well

 

Those match your truck really well.

 

Thanks I just prefer to keep OEM

 

I love the TRD Rims. Was looking at a set. Found one on FB for $900. Was thinking about it.

 

I will disagree with most of your post. If you go with modifications you have the choice of using parts that are far superior than what the manufacturer provides. The manufacturer has to provide a product at a competitive price point. If you choose quality aftermarket parts they can be far superior than factory.
