I looked at using recentered military wheels. Only the 24 bolt Humvee wheels come close to the weight carrying capacity - and those are the hardest to come by. I know several people who have tried recentered Humvee or Hemtt wheels and were unhappy with them (and are now using something else). They look cool but ride like crap.
there are some. for a while im sure the factory upgrade wheels on the Iveco Daily was a 16.5 inch and speed was electronically limited as a result. im pretty sure there was only one or two different tyre options in that size available and they were twice the price of a 17inch
They're 16s, Michelin XZLs. You're right tho, only 16s in that size/weight are 255/100 and 11.00, both by Michelin and both exorbitantly expensive..
I don't know of any 16.5s here though.
