P-32 Wheel/ Rim

[max49]

I'd like to buy an extra wheel. Does anyone know what GM truck it came from? Auto parts stores and even some GM dealers get a dazed look in their eyes when you say u need something for a WH P-32 chassis.

The numbers you need should be stamped somewhere on the rims. It may take some cleaning to see them.

TIRES AND WHEELS

WHEELS
Workhorse chassis utilize different wheels depending on the GVWR.

The W Series 16,000 lb. and 18,000 lb. GVWR chassis have an 10 hole wheel with 5/8” wheel
studs, 27mm lug nut and requires 150 lb. ft. torque. These wheels have a 3750 lb capacity.

The P Series 12,300 lb. chassis have 8 hole wheels with 9/16" wheels studs, 1” lug nut and
require 140 lb. ft. torque. These wheels have a 2,440 lb. wheel capacity. The 14,800 lb., 15,000
lb., 16,500 lb., 17,000 lb., and 18,000 lb. chassis have 10 hole wheels with 5/8” studs, 1” lug
nut and requires 175 lb. ft. torque. Both front and rear wheels have a 10 hole bolt pattern for
proper tire rotation, although the front axle only utilizes 5 holes and the rear all 10 holes.
This is due to the differences in carrying capacity, single compared to dual wheels, and the rear
axle is the driving axle. Prior to the wide track suspension the wheels had a 2,760 lb. wheel
capacity. All wide track suspension, which begin in 2000 model year, and the 14,800 lb. chassis
starting on 1/21/02 have a 3,000 lb. capacity.

Workhorse has utilized three wheel suppliers Accuride, Maxion and Alcoa. Accuride provided
all 19.5” steel wheels until 1/21/02 and the 22.5” steel wheels until 2/18/02. After those dates
all chassis with 19.5” and 22.5” were standard with Maxion wheels. Alcoa manufactures all
aluminum wheels utilized on our chassis. The following chart provides part numbers for the
most current wheels utilized.

I get that dazed look when I ask for a simple oil change. It is real clear to me that in my area I need to own my repairs. Good thing I spent some of my youth at a Volkswagen repair shop and on a farm on the west slope of Colorado.

Do you have any RV BoneYards near you?

Otherwise, the DW lets me stop in at one of those surplus stores in the Elkhart area on our trips out east. We've found some great upgrades and have always found installers.

Do you have the 22.5 wheel or 19.5? I got a dazed look when you say P32 also!

[max49]

The P-32s been around since before the W series. I thought they all had 19.5 tires.

Max, There has never been a P32 or "P" series of any type delivered OE with 22.5 tires.

I did a little digging after I posted and that's what I could find also. I just had to ask to know, thank you both.

[max49]

Thanks giys. Does anyone know which model GM truck uses the same 19.5" wheel? That's usually the first thing the store asks.

Max, Go to a tire and wheel place. They will know what wheel you need. WCC bought the complete kick and caboodle from GM. The wheels used on P Series may not be the same that might be used on the 5500 or Kodiak trucks but those are gone as well. If you go to a truck tire store they will know what wheels you need. Bring the specs that I show in the table.

Thanks Driver,I'm getting 4 XDS2 tires mounted on the rear as we speak at Big O. I couldn't resist the price And even you said I might should have snow tires.
They told me I'd better off to get the rim at a trk tire place too.
