Ok I need some help on this one, I have the adapter plate dish in but my wheel is rubbing big time on both sides, check out the pictures.

I finally got to actually putting these on the truck but Im kind of stuck, how do we air the rear tires up? the valve stem is so close to the hub that I can't get my pump fitting to go on it, is it only able to be aired up with the wheel off the truck? Also, do we use the stud with the square head again? I put the sqaure head stud back on and then mounted my wheel/tire on.

I have the aluminum Hutchinson wheel
It's best to flip them around and have dish out or air them up before installation if you want dish in. I'm pretty sure you'll have to flip the hubs if you run dish out so the rears are in line with the front unless you don't care about that. All of mine are dish out and while it may not look as nice on the rear that way, the valve stem is 100% accessible. As far as the front rubbing, I think it's either different lug studs that push the wheel a little further out or there's a spacer used, I didn't install mine, but perhaps @Godspeed131 can chime in, my truck was his truck and the tire installation is spot on with plenty of clearance on the front.

I’m not the most knowledgeable on the different wheels available and there are other people on this site that would put me to shame but I’m not sure what those wheel are, maybe buffalo wheels, but the wheels that you are using appear to have too much of a positive offset that wont work on the deuce as is and that’s why its rubbing. The ones I used are different, with a more negative offset and were another type of hutchinson. Ill post a pic of the wheels I used on @ToddJK ’s truck.

On the topic you asked about the valve stems and lug nuts, with the flipped hubs that brings the load on the bearings in alignment and that puts the face of the wheel with the valve stem out so airing up wont be a issue. the lug nuts how you have them will be ok, but it is a lot better to grab 24 of the same lug nuts that the front uses and that will replace the two piece bud lug nuts used on the back and will simplify everything.

I was going to write a new thread about this but I figure this would be a great place, I've been running the super singles on the M35a2 for a bit and here's the difference for me (Pros and cons)

Better cruise speed 55-58Mph at 2200-2300 Rpm, much safer than the 45-48Mph on a 70Mph freeway that I use to do

Slower acceleration big time, this is one of the things I miss the most about the smaller 9R20, after I turned the fuel up a little, the truck seemed very sporty and zippy while still staying around 900 Degrees on the EGT gauge, with the 395s, the truck is very slow on acceleration in comparison (Take note, what's zippy and fast to me is most likely slow to you, I daily a humvee)

Grip, the 395s are far better off the payment and in wet weather, I never had any issues with the NDTs on wet pavement because I'm cautious with them in wet weather, in the mud and off pavement, it's not even a comparison, the 395s are a lot better.

Climbing inclines, thankfully I'm in flat Louisiana, but I do go over the I-10 and 210 bridge which is a little bit of a steep incline, the NDTs goes over the bridge with no problem whatsoever and still maintain 45-48 while staying at 900 on the EGT gauge, I cruise with the super singles at 55-58 and it will drop down 45-48 while climbing, the EGTs will be around 1,100-1,200 at that speed. I typically don't like passing 1,000 on the EGT gauge that much.

Turn radius, this depends a lot on what wheels you're running, I'm running the MRAP wheels with the 10.9In backspacing and my right turn is cut short by a lot due to the tire rubbing the steering box, I have the waterloo power steering kit installed, unfortunately you'll get this with almost any power steering box that has to go outside the frame. This can simply be avoided by going with a wheel with a better offset, but your tire will stick out the fender a little, and of course these bigger tires will put more stress on your wheel bearings, transmission, steering, and suspension components etc.

I get about 2MPG more on the 395s in the city, highway is the same but with both of the tires I only cruise at 2200 RPMs mostly

Braking, the brakes are not as bad as I thought they'll be with the 395s but its obviously a lot better with the NDTs, the one thing I did notice is if you have to hard brake, the NDTs will slide in a weird a way, whereas the 395s wouldn't, they'll just stop straight, while the NDTs kind of get this pull to one side slide.

Carrying weight, I really can't speak that much on this since the weight I carry is usually around 2,000-3,000Ibs which is not even noticeable while driving the m35, I would say this, the smaller tires does give you a lower height which makes loading and unloading easier.

Emergency, this is one of those things I'm just throwing out, if you get a blowout while being 100 miles from home, you're basically screwed with the 395s unless you carry a spare in the bed. Also, you'll be on one hell of a ride if you blow one of those steer tires.

Ride Quality, the 395s are a lot smoother and quiet, I notice with the NDTs any crack in the road or pothole would try to jerk the steering wheel a bit, while the 395s just run over them small cracks and potholes like nothing. I will add that the smaller tires are easy to get balanced in comparison to the 395s, surprisingly the previous owner had the wheel and tire balanced where truck would shake at any speed, with the 395s I do get a little bit of shake at 50-58 sometimes but the antifreeze in the tire trick does pretty good.

In my personal opinion, I'm kind of mixed on what tire I prefer, I feel like the truck was a lot more fun to drive around with the small NDTs because of the acceleration and the right turn radius, also having a spare that I can easily pick up and change was nice too. I would also say I feel like I wasn't stressing the steering, multifuel, and spicer out that much with them. The 395s feels like it's just too much for the multifuel. Now the grip, cruise speed, and ride quality are almost unbeatable with the 395s. I would say this though, if I had a better overdrive transmission that let me do 55-60 Mph at 2,000-2,200 RPMs, I would most likely look for a better tire and wheel that's similar to the 9R20 in size or go with the 11R20s

I ran a tandem axle 5th wheel dolly with duals on stock 5-ton wheels to pull a big water tanker (5K gal) with my M54A1. Plenty of space between the tires, and everything else.

I've seen 12.00's on a M35 with duals on stock wheels, hauling water, of all things. Didn't seem to have any rubbing problems, but where it ever went was around the dirt roads at a dump. Not much 50 MPH action there...
