M151A2 Tire source

I have a new tube still in the box out in the shed, I can look and tell you what it says but I am headed out to a doctors appointment right now. So it will have to wait until I get bock in a couple hours.

Isn't there also different diameter size valve stems?

Thank you Rick sorry to be such a pain

I think it's a TR-15 stem with offset.

I just got home and not enough light to see out there. But I agree with Hambone on the tube. You can't go by the pics that you show, it says it is just a representation. The tube they show in that pic looks like a motorcycle tube with the centered stem. There are some automotive uses where the valve stem is centered but they are very wide wheels, specialty stuff.

This is from the old Wiki files that I have not been able to get on here yet.

TR15 inner tube air stem on 7.00×16 tubes. This is the short fat stem that is correct for the M151 rim.

[Col Batguano]

Thanks for the help everyone. Like Rick said the center valve is for bike/motorcycles or custom. The off set is what im looking for in regards to M151 rims/tires. Im gonna pull the trigger on new tires from Summit, been saving 6 months to get em.

The military tires are the thing if you want authenticity. I will be putting civilian tire on mine next. After getting caught in a monsoon storm down in Virginia and driving on a mountain road I could feel that the tires were not gripping all that much. Being a former race driver I can feel when it is on the edge but when the steering starts to feel real light you are getting into dangerous territory. I much prefer to only feel that when I am really pushing the limits and not regular driving in a rainstorm. Thankfully I had a guy in a pickup behind me that saw I was in trouble and he got behind me with his flashers on until I could find a place to pull off.

I had to replace all five tires last year. There are lots of good reasons to change over to a modern type of tire, but I wanted to keep the truck as original as possible so I stayed with the NDCC profile.

M151 Tire and Tube Configuration -34P 001.jpg

As you can see from the -34P illustration, the installation does not include a flap. I don't know of any reason why you shouldn't install a flap, but a flap is not required. The designation for the correct tube stem is an "Offset TR15."

This was my solution:

I chose Coker Tire for both tires and tubes. Coker has been a well-known supplier of tires for vintage vehicles since 1958 and they maintain a good reputation. I've only ordered from them on two occasions, but I've been pleased with both their products and their service. You may find lower prices somewhere else, but if you're planning ahead and have time to be patient, Coker occasionally offers free shipping (see the post two down regarding possible discounts).

Opinion section:

Safely mounting tubeless tires on a tube type rim requires some research. Tube, and tubeless tires have different bead configurations. For that reason, tube and tubeless rims are of different designs too. Tubeless rim geometry requires a "Safety Retention Lip." I didn't want to go the tubeless route, so I didn't look into MUTT rim compatibility with tubeless tires. In a case of sharp cornering, I suspect a MUTT would roll over long before a tubeless tire bead will roll off a rim, but . . .

Installing a tube in a tubeless tire opens a whole different set of issues, but again, given the typical speeds of a MUTT, it probably isn't critical.

I reconditioned three rims and mounted six MUTT tires and tubes last year. I had a local shop dismount the old tires but, for several different reasons, I installed all of the tires and tubes myself. I can work up a post on that process (tools, techniques, lubricants, etc.) if anyone is interested. Let me know.

Mark,

I’m interested in your tire mounting process. I am looking for tires now for my A2 and this post answered all of the questions I have.
Did you balance your tires?

A tubeless rim does not "Require" and safety retention bead. That is there to prevent the bead from sliding off under turns at very low pressure. With normal running pressures there is no problem. The retention bead came onto the scene quite a while after tubeless tires. The tire sealing bead and the rim bead are the same angle and that is what is important. Tubes were required mainly because the military live 50 years in the past with a lot of it's vehicle specs. They figured a tube can be repaired in the field. Yes it can, and it takes a LOT of work to do so. A tire can be plugged in a minute without pulling a tube out of the tire and reinserting it and then putting the tire back on the rim without pinching and cutting the tube. No tire plug? Then steal a wood screw or sheet metal screw from somewhere and screw it into the hole. It will get you back to the shop. Has worked for me many times, I left one screw in a tire for years due to forgetting it and it held all that time.

Quick update:

Disclaimer: I have no connection to Coker Tire other than being a prior customer. My only reason for posting this information is to help other G838 members find the lowest price possible for tires and tubes. I didn't have this information two years ago, so I missed out on discounts that were (may have been) available.

I exchanged emails with Sara Henshaw, one of Coker Tire's customer service reps, yesterday. I asked if Coker offers any discounts that I could pass along to the G838 group. She informed me that, in addition to periodic promotions, there are two ways to get a discount:

You can receive a 10% discount on your first order if you sign up for Coker Tire messaging:

https://email.cokertirecompany.com/p/5P ... club-offer

Also, . . .

The Coker web site ordering process does not include a provision for requesting a 10% veteran discount. However, she said, "If they mention it on the phone or through Live Chat, most representatives will give them 10% off." It doesn't sound like a guarantee, but it's worth a try.

I put Ironman non military tires on my A2 two years ago, no tubes, did nothing to the rims and the previous military tires had likely been on for 30 years. Have not had any air loss. The ride and handling is so much better that I will be changing out the tires on my other A2 as well and keeping a set of Military's for shows as I have an extra set of rims
