I believe these are the DR-5 model, identical to the current DR-33 wheels here. 4 bolts for sure, I think it's 4x100.
I put brand new rubbers on these for a half-summer of driving (maybe 1000km if that) -- 205-45-ZR17 Kumho Ecsta Supra's. Cost nearly $700 at MyTires.
Each wheel needs a touch up; there's minor curb rash or scuff marks on each, but nothing unrepairable.
Pick-up only in Calgary; $350obo. If I can find close-up pics I can email them to any serious inquirers.
