Switching Duals for Super Singles on M809

[Firetrucks Only]

I am changing out our stock tires to Super Singles (Michelin X 395/85 R20 XZL+) on our 1972 M809.
My question is do we need to change the lugs on the rear to fit the new super single rims? I know we need the correct lug nuts for super singles.

Nope. Existing wheel studs are fine.

My m818 has the 16.00's mounted on hemtt rims. The original studs work just fine. I'm using the shoulder lug nuts with part number M-3208 and M-3209. They are for both left and right hand threads. These work great for the hemtt rims, but I'm not sure if they work well with combat rims.

Not needed on 939 combat rims just use same nuts as front wheels.
