Modern tire size to replace 900x16

[rickf]

Are you actually running the 315's on your truck? If so any possibility of getting a pic or two?

 

[rickf]

So true. I'm researching this same topic which is how I came up with the 315. I also found another tire but you loose even more OD (~2"):
255/85R16 @ 33.1" (6.5" min rim recommended)
vs
315/75R16 @ 34.6" (7.5" min rim recommended)

I think the stock tires are in the 33-34" range. My other 37 is half buried in the weeds so I can't get an accurate measurement.

No, not yet. I still have plenty more to do before that. I have seen those size tires on an M37 and that's what I have as a 'must do'.

No, it's more like 36".

 

[Rdinatal]

No, it's more like 36".

By the specs 35.2" (+-)

Only thing my feeble brain could not wrap around was the hmmwv rim half studs and nuts are not beveled seats so if that is now the point of attachment on the new adapter plate how are they "true and centered"

Many ways to accomplish that.....

Correct option would be a plate with a step machined to it on its backside, fitting snuggly into the opening of the now modified outer half (cut & turned on the lathe).

Easiest (& cheapest) way: a few weld spots on the wheel inside, after confirming that everything is bolted together and running true.

Stock 9.00-16 NDT tires are just a shade over 35" diameter.

STA Superlug 9.00-16 tires have a more modern tread design than the original NDT tires. These are Bias ply tires. They are sold by Vintage Power Wagon and by Coker Tire (and probably some other sources as well). They are 36.3" diameter. I've seen them on an M37, and they look good. Much better in wet or snow than the NDT tires.

I also like the Michelin XZL 9.00R16 tires. These are radials. Outside diameter is also 36.3" diameter. If you want something in close to the original stock size, I think these look great on the truck and have better traction than the NDTs. Unfortunately these seem to be just about impossible to find in the US these days. In Europe, you will sometimes see these referred to as Michelin XZL 255/100R16.

If you don't mind going to a larger size tires, I have Michelin XZL 11.00R16 tires on my M37. Diameter is 38.7" They fit the stock rims and there is no rubbing with the stock suspension with the wheels fully turned. Those are what are on my truck in my profile picture. This size Michelin XZL is not difficult to find in the US. Colony Tire in Norfolk VA is where I got mine (try Nate Potts npotts@colonytire.com if you are interested).

Dang! I went right past Norfolk on Thursday with that M37 on the trailer!!! Could have stopped in. But I am guessing those 11.00's are far from cheap!!

Thanks for all of the size verifications, that kind of helps me zoom in a little. I want to stay in the same ballpark. I do not want to go smaller diameter for sure.

Yes, the 11.00R16 is not cheap. Last I checked about 5 or 6 months ago they were getting $450 each for them. (They were a little bit cheaper when I got mine a couple of years ago.)

Colony Tire used to have the Michelin XZL in the 9.00R16 as well as the 11.00R16, but the last few times I've checked, the 9.00 were unavailable, and they weren't sure if/when they would get any more in.

Sorry it took so long. 315/75R16:

 

[rickf]

Thanks for getting back to me with the pics. I think I am going to go with the hummer tire conversion setup using Hummer rims cut out to fit on adapter plates, I forget who has the plates but it is a good solid setup. Then I just hope the hummer tires will be replaced with something compatible on the hummer replacement in the future so I could still use the 8 lug centers mounted on the beadlocks.

What size tube did you use?

Is this a radial tire tube?

Yes, radial tubes.

Here's the info from Charles T:

The tubes that work best are lowboy trailer tire tubes, size 8.25X15" tubes with the correct brass stems. Don't let the 15" tube size confuse you, these work great. The correct stem length is very important, be sure they don't get tubes with extra long stems. They stick out too far and are prone to being hit and damaged. The flaps should be a 16" diameter for use in radial tires.
