OEM wheels are JWL 690kg. It will be right on the wheel so you can take it off and look for the info.

It's important to note that most OEM wheels for cars sold in multiple markets will also have TUV (Germany) certification. TUV standards are the highest in the world, higher than JWL (Japan) & SAE (USA). TUV wheels are heavy! For this reason an OEM 690KG rated wheel will often be capable of handling much higher load than 690kg. Aftermarket wheels not sold in Germany will not have the TUV rating so they're built much lighter.

This can be a complex subject so we wrote an article to help make sense of it: http://949racing.com/how-strong-is-your-wheel.aspx
