Just thought I'd share pics of my van with 12" vs 15" wheels. For my 1990 Sambar, I found that to be rub free and and not stick out past the body a 15x5.5 +45 offset 4x100 pattern wheel was perfect. The wheel center bore required is 59.1mm*. I went with junkyard 2008 Mini Cooper Clubman 15" 6 spoke wheels. They were a great deal and I loved the way they looked. Only thing, the center bore of Mini's is actually smaller than Sambars, so I had to have the center bores machined out from Mini's 56.1 to the Sambars 59.1. My local machine shop did the work in a couple days and for a total of $178. So even with that, the wheels all setup were a steal. I do still need to cut a pieces of vinyl to cover the "mini" on the center caps... There are certainly other wheels out there OEM and aftermarket that will work without the need to machine anything (or use spacers). At least for my van that meant 15x5.5 +45 with a 59.1mm center bore. Tires: I went with Kumho Solus 155/60R15 as they weren't much taller and were the same width as the existing tires to up the odds of not rubbing. So far I like how the tires ride and grip and there is no rubbing from lock to lock. Anyways. I thought I'd share as it wasn't that long ago I was searching everywhere for this info.
