It looks like I was mistaken. Looking at the Toyota brochures with all options and checking part numbers, there are no wheels shared by the 2 platforms. My brother bought a '21 Camry last year with what I assumed were stock wheels, but the previous owner must have put Sienna wheels on it.
Ok, this all makes sense. I figured there had to be limited disclosure standards after not being able to find any good sources on this. I'm trying to stick to oem manufacturers for the quality assurance, but good to know aftermarket ratings may not be dependable. Thanks for the reply.
I'm new to the site and am hoping some of you good folks can help me understand what I need to consider when looking at wheel options for my vehicle. I've searched this forum and gathered that wheels are typically designed to have a load rating that meets or exceeds half the heavier axle weight...
