Help me ID these wheels

My experience with a Duster was a LOOONG time ago, but....
I think you can probably get a 255x60 under one on those wheels
The sevens will tend to suck in the sidewall width more than an 8.5 would, I don't think 27" is too tall, and if those have 4.25 backspace, they'll tuck the tire in nice and close to the spring.
If they end up TOO close to the spring, spacers can solve that. If you do need spacers, get billet ones, not the cast aluminum garbage! I have used spacers to get the tire exactly where I want it on a 11 second car, and some billet spacers I made on my nine second car. Quality spacers don't bother me a bit, as long as quality long studs are being used too.
