Lug Nut size

PeoriaKen,
May I ask, what "Type" of wheels do you have? Are they steel with Stainless steel wheel liners or, are they "Aluminum"? If, they're Aluminum, it's possible that, (like ours) there is a stamped number on the lug nut caps, (that is if you have caps). On mine there is a "33" on them. That is, mine are 33 mm lug nuts. The same, or very, very close in American sockets is a 1 5/16". This is assuming that because you have 22.5" wheels, your lugs will be the same as ours. Just guessing here.

P.S. Use a tape measure and measure across the stud, from a flat surface on one side to the exact opposite on the other side of the lug nut and see what you get.

If you have the stainless steel wheel covers, there is a center piece that pops off. It is about 5-6" in diameter. Look for a pretty well concealed place to insert a flat blade screw driver and just pry them off.

Thanks Guys I will check when I get home tomorrow.

Workhorse W-22 chassis has Stainless Steel Wheel Liners

and the

Workhorse W-24 chassis has Polished Aluminum Wheels.

the wheel linerss you just pull two of the nut covers off and the liner should slip right off.

The Aluminum Wheels, if you don't have a socket big enough, you don't have a rachet big enough!! But the hub cover should turn off. Depends on how it is set up.

double post - sorry.
