73' B3 340 Duster pro touring build

For some reason, tire selection in the 27"-29" range is very limited. I agree, you might as well fill up the space you have.
wouldn't you know it I found what I thought would be the perfect tire, but when I went wheel looking for a 17"x12" nobody make that size except ZO6 corvette wheels (not a deep dish wheel). If anybody knows of one this size please let me know I looked at billet specialties, centerline, weld ,ect.....anyway heres the specs on the M & H Racemaster
