Toyota 86 Wheels, Rims max spacer width

When I've researched such notions in the past I constantly ran into just about every tire place and wheel seller making it clear that wheel spacers are not something they will recommend due to liability issues. As in anything that changes how a wheel bolts to an axle it's something a business insurance provider is a modification they'd prefer to not allow. That doesn't mean it's unsafe, just beyond what's safe from a liability perspective. Handling wise, a wider stance will definitely improve things... But collision wise, it add a small amount of weakness to the design.

And in all my years on PriusChat, I've not seen any discussion of this. Most people simply buy wider wheels to do what you're trying to do, but of course that can cause a big hit when it comes to gas mileage. But hopefully some others who know more than I will contribute to this discussion?

 

The 86 wheels are +48 7.5 width IIRC

I run OZ Ultraleggera 17x8 +48 w/ 25mm spacers on all 4 Corners to "Flush" my wheels, Hope that can shed some light.
