LMTV Tires + Flipping Hubs in My Deuce - Is it needed?

[missionhomeloans]

Hi All -

First time deuce owner here. Currently have stock tires on there with duals in the rear. I purchased some LMTV tires to put on there and have the adapters from Western Canadian Rockwell to make them work.

My question is - I know you typically need to flip the rear hubs for spacing, but am curious if that applies still when going from dual tires to singles?

Sorry if this is a silly question. First timer here. I've done some searches but haven't really seen an answer that's applicable to the LMTV tires on the deuce.

I don't believe LMTV rims will work, even with adapters.

MRAP rims with adapters work, and need the hubs flipped for best results and cosmetics.

Got a link to your adapters? And a pic of your wheels?

Here's a link to the adapters https://westerncanadianrockwell.ca/...8S8TF7u3zlZwvDHJDG_aem_rLtFQpcQoJzHx0z7xBaqHA

Pic of the wheel attached. Western canadian said that these adapters were made specifically for this wheel.

I was unaware those adapters existed. That makes my MRAP comment irrelevant.

And with the differences in offset, I don't know if flipping the hubs is needed.

I'll watch this thread and learn right along with you.

Welcome to the hobby by the way.

Flipped hubs look better, and all the lugs are facing out. I know, it's my 5-ton, same deal tho.

What do you plan on doing with the truck? It's always been my understanding that singled-out rear wheels should have the hubs flipped otherwise heavy enough loads (of which I'm not sure how heavy) in the back of the truck will accelerate wheel bearing wear.

To be fair to the 5-tons, it's also my understanding that the 5-ton axle design is beefy enough that singles can be run on the rear axles regardless of the hubs being flipped. I like the look of 5-tons with singled-out rear wheels without the hubs being flipped.

My A3 came from the factory with the rear hubs flipped because they all came with super singles. Were it an A2 and I wanted to single it out, I'd flip the hubs for the mechanical wear concerns, even though I'd baby my truck

I have a M52 that I have already converted to singles and am currently in the middle of converting a M51. The singles won't mount without flipping the hubs. The tires would rub the springs. I don't think there is any concern of accelerated bearing wear. It doesn't change the tire mounting location but an inch or so in relation to the wheel bearings. You will need new studs for the rears as you will have to remove them and turn them around for the conversion. I bought 20 extra LH & RH lug nuts like the fronts so the would all match but I guess you could just run the barrel nuts.

Never mind my other post I missed the "deuce" part when I first read it. I never singled the 2.5 ton only 5 tons

....... I don't know if flipping the hubs is needed.

It is...... Otherwise there wouldn't be enough room (btw hub flange and drum) for the six nuts & studs holding the adapter in place.

This is a M51 but it will be very similar

Pics are a bit big. This is a M51 5 ton but it will be very similar. A single tire is a wider rim and where the lug nuts go is flatter and usually in line with the edge of the tire so the backspacing is different from the back of the face with the lug nuts to the back of the tire. Dual rims have a different offset one is mounted one way and the other is flipped around so the flanges touch when they are on the vehicle. The wheel hub has the same bolt circle as the axle on both sides one side to the brake drum one side to the axle. It needs to be flipped around to move the mounting flange outboard to be able to accommodate the wider single wheels. Plus it gives you a chance to check the wheel bearings and brakes while it is all apart.

Here is one flipped

The MTV wheels that I have for the 5 ton are made to be mounted studs out as singles. I don't know if the LMTV wheels are the same or not. The mounting holes for the lug nuts are only beveled on one side the inside is square edged. Being a lug centering wheel they need the tapers to center the studs up in the holes and in turn center the wheels.

I don't mean to hijack the thread and it is 5 ton stuff but I am literally in the middle of replacing torque arm bushings and putting singles on this truck. I am tired of the old NDT tires and locking ring rims. I have the wheels and tires waiting on me to get around to them and when the bushings gave out last fall the rear rear tried to leave. We ran a M35A2 for a while before these trucks but the lack of power steering and the odd 6 lug wheel made it less desirable. We often overloaded it as well so we switched to the 5 tons.

Exactly what I've seen over the years. The deuce was never meant to be a real heavy hauler. Within the design specs, it was a great tactical vehicle. Simple & robust , good off-road. It was fielded simultaneously with the M-39 (G744) series 5-tons to handle the big jobs, with a lot of commonality in design.

Luckily, the original studs will work OK if not too battered by removal. If OK, pound 'em back in the other way. The web on the LMTV 10X20 wheel is the same thickness as the 10-bolt Budd.
