Help deciphering my wheel markings, they are different than what I'm familiar with.

J15 x 6JJ DOT TOPY 1619 87 S3.8 NISSAN

 

All I can tell is they're 6" wide and 15" diameter. I'm trying to figure out the offset and pcd so I can try and trade on my local 4x4 forum for some 31"s.

Is the S3.8 positive 3.8" offset? Seems like that could be correct for how far they sit in the wheel well.

Google how to measure wheel offset. It's pretty easy, just need a tape.

Yeah I know I can measure. But figured I try and see if anyone had any idea about the weird markings for these wheels. They're not like any I've seen before.
