    Default 6 new tires on my M923A2, what pitfalls can I avoid?

    I am new to this, so please forgive my ignorance. I recently purchased my M923A2, and it needs 6 new tires. The ones that are on it are dry rotted and the sidewalls are cracking, and I have already blown two of the Michelin tires and the only ones that still look good are the Goodyear's. They are the 14.00 R20's and I will be replacing them for the same tire, as I have no interest in going to the 16.00's. I have already gotten one of the split rims apart, it was a pain in the butt, as the tire had no sidewall to pry against, but with lots of penetrating oil, it was done.

    The rims themselves are in good shape, no rust, the benefits of living in the desert. I am repainting and acid etch priming the rims where needed just to ensure no problems down the road. I am getting new 1/4 inch o rings, and I am thinking of replacing the valve stem grommets as well, while I have the tires apart. New valve stems in are order as well.

    Are there any tools that I should get that would aid in the process? Any tips for a new guy? Does my plan sound about right?
    Thanks in advance, you guys have all be a great help so far, and I really appreciate the input..

    Thanks!!

    While you have the rim apart, I would change the o ring and entire valve stem with seal. Then, you dont have to worry about it (leaks) for a long time. Also, 1400s are becoming harder and harder to find, as they are no longer used by the military. Either 395s or 16s are you choice for newer dated tires.

    As far as tools, good pry bars, a tire chair, good impact with plenty of air, 1 & 1/8" deep socket for the rim studs and forget the size of the lug nuts, maybe 1 & 1/2". Lots of motivation.

    14's are getting scarce. I'd go with 395s or 16's . My preference is 16's on hemtt rims but 395s are much cheaper and work better on the stock 5ton combat rims.

    In your position I'd go 395s.

    Thanks for the info. Im going to start looking into that size now. I definitly don't need the higher load rating for what I am doing.

    The 395's are noticeably shorter and lower your top speed. They are my recommendation as well. Here they are on my M929. Definitely repaint the seal areas, new o-rings and valve stem seal. Load rating on the 14.00 AT-2 GY is about 9700 and the rating on the 395 Michelins is around 12.500.

    tobys, I've thought about doing your wheel and tires setup on my M51A2. Going need to bite the bullet sometime, the NDT are getting old.

    Have you had any issues when loaded? Worry about a blow out?
