40" military tires
 
1 Attachment(s)
sorry for being a post whore but i need answers before i possibly send a money order out this weekend. the tires are 40"x12.5"/20r. they are military take offs. does anyone know anything about these tires? can i run them on the street? anyone know where i can find info on them? can i run these on some 8 lug 20x10 like these http://www.tireandwheeldeals.com/ima...s/kruz/K18.jpg

What is the size on the side of the tire? We have a tire like that on our 6x6 tractors that we pull our trailors with. They are the same pattern but I believe ours are 14.00x????? Ill have to look tomorrow. Kinda curious cause the tires we have are pretty tall

GMC71k20 10-14-2004 08:24 PM

they are 40x12.5. they are used on military 6x6s

Those tires are made by Michelin. Here's a link with some specs.

they are used on the national guard extended use program M35A3 they are a pretty good tire they have a bit of a hum going down the road though. I don't know what speed they are good to but most military truck tires shouldn't be run over 70 mph as they are built by the lowest bidder and tend to start to come apart over that speed as no military vehicle is designed to go over 55-60 mph. if youv'e seen what happens to a m35 series when the tire comes apart at highway speed you'll understand why they only go 55.
P. S. I order those tires quite a bit lately- dry rot - probably make cool tires on an off road only vehicle!

1FaastC10 10-14-2004 10:29 PM

hmmm... Michelin... long lasting tires. sounds like the ticket for my K10 so i dont wear the crap out of my Swampers... :metal:

GMC71k20 10-14-2004 10:30 PM

are they badly dry rotted? i only plan on using these for shows and playing around. would you see any problem with me mounting them on a regular 20" truck rim?

Steven Sellers 10-14-2004 10:33 PM

You must have one heck of a lift if your gonna put these on a truck. As far as offroad we did stick one last year but we were pullin a 60,000 trailor out of a pretty muddy spot. The only problem Ive seen is our big tractors cant get any wheel speed to clean the lugs well at least with all that weight attached. I can get you pics of them on a 6x6 if you would like.

1FaastC10 10-14-2004 10:54 PM

they're available in a 38.7" size for a 16" rim too.

GMC71k20 10-14-2004 11:01 PM

ya the pics would be nice. where have you bought yours from?

GMC71k20 10-14-2004 11:05 PM

do you guys like the rim i posted? any other suggestions for rims?

GMC71k20 10-14-2004 11:08 PM

1faastc10, if you want i can give you this guys e-mail address. i havent done any business with him yet but hes got good feedback on ebay. he also has some 36x12.5 hummer tires for sale. i might get some for bombing arond town and some off roading

1969 GMC 10-14-2004 11:15 PM

do you still have the stock dana 44?

with 40" tires it is time for a dana 60 up front. not just for the strength (Although you do need it)...you need better brakes to stop some heavy ass tires like that. You probably know this already, just thought I'd chip in my 2 cents.

GMC71k20 10-14-2004 11:30 PM

ya, im on the hunt for a dana 60 and plan on doing the black birds custom rear disc conversion. just need my vaca/sick/holiday/personal pay.

1969 GMC- what do you think about this, im not a fan of 20s but on 40's they shouldnt look half bad,

andrew king 10-15-2004 02:19 AM

IS it the same guy on ebay lives here in California if it is watchout !!!! I was going to buy some Hummer wheeels of him military style and he was kind of shady to say the least wanted me to send a money order to a po box different town from where he lived and then said 2-3 weeks for delivery I told him to F#@K off .. Anyway good luck

2wdBlazer 10-15-2004 08:49 AM

8 inches WILL NOT clear 40's. Better have some more lift on the way if they measure a true 40. Like I said before, if you run a true 38, you will be a street queen. No clearance is bad. Just say no to the SAW-ZAW!!!

GMC71k20 10-15-2004 12:21 PM

I'd say yes to a body lift. alex ran some 40s with an 8" lift on his old truck.

Andrew King - this guy is based out of PA

Me and mac67 were talking, and we think these tires might need a rim with a special bead. Unless i can find someone that has done this before I might pass. Too big of a purchase to take a risk with. I dont want to have to donate them to the local playground after I realize theyre useless to me.

I have 39 inch mickeys on my truck, and they have only rubbed once and it was the droop side of the axle that did. my only lift is skyjacker all spring 8 inch, paired with rotted and mashed body bushings. i know they aren't 40 inches but they measure around 38 3/4 ish. it was no trailer queen before i started taking it apart.

If you are looking for tires i would sell you my 39-15/16.5 mickeys... only have like 2500 street miles on them and about 15 dirt. they are in great shape.

That's funny. Mine rub on just light-moderate stuff and I have 9 inches. Mine measure about 38.2 inches. Only rubs the rear corner of the front fender well.

Budweis 10-15-2004 02:48 PM

why put it on right on the extreme of rubbing? just curious. to me a 4x4 is worthless if cant use it hard off road. just wondering:)

You talking to him or me? My truck has a 6 inch spring and 3 inch body that came with the truck. I will probably swap to 8 inch springs or run 36's next time. Undecided.

gn4u2c 10-15-2004 03:05 PM

My old blazer had a 8' lift and it was NOT enough for 38's on the trails I peeled the hell out of my fenders :) well saved me time with the saws all but it gouged the tires up a bit also.

Budweis 10-15-2004 05:30 PM

meant to ask for the two people mentioned who run or want to run 40" tires on a 8" lift truck. basically i see it all the time where people set up their 4x4's to the point where tire will rub on any off roading and was just wondering why? isnt the whole point of a 4x4 to go in rough terrain? am i missing something?

1FaastC10 10-15-2004 07:02 PM

im running 6" and it will clear 39.5"s+ with no problem. i love my body saw. :D

GMC71k20 10-15-2004 08:34 PM

these are gonna be my show tires, right now i have a set of 35s for fun and might pick up the 36 hummer tires.
ryanroo - where are you located? i am interested in your tires
