TRD wheels, center cap size

Voxx says "Compatible with OEM Cap Part Number: PT280-34200-02"

So those aren't the OP's wheels if the OEM caps don't fit.

 

Well that's unfortunate if so. After extensive image searching, the only other wheels that come close to OPs were in a TacomaWorld thread from years back. In a FactoryStyleWheels thread someone had ebay knockoffs that were claiming to be FSW wheels. Which they were not. Yes, a copy of a copy.

As I said before, Voxx are the only wheels that have that weird concentric circle around the lugs. AGP, FSW(no longer in production I believe), the AlphaOnes you linked, and even other current ebay knockoffs all have the correct smooth profile from spoke to hub center.

 

I've been scouring the internet to see if I can ID them and I'm stumped. I got into those tacomaworld posts too.

@Toyoter i might recommend hunting around on eBay and see if you can find some caps with measurements listed.

 

Posts 24 and 25 are a 17x8 wheel. That's my best guess. Could contact them for measurements on the caps.
