Help: M1009 Tire purchase tomorrow

[lindyp38]

would that also apply to the m1008 .......?

thanks

All CUCVs except the M1009 have 16 inch tires & wheels.

The M1009 has 15 inch tires and wheels.
With 33 inch tires you can comfortabley maintain 70 miles
per hour all day long and the engine RPM is still slightly less
than with the OEM 31x10:50 x 15 tires.
Good luck

PS: the M1009 wheels are 15 x 8 with 6 bolt.

Jimm1009. not that you're the answer man, but I was wondering if you happened to know why they reserved this special honor for the 1009. Comfort? Off-road flexibility?

Because I know that all of you are on the edge of your seat (uh huh, sure) I thought I would share that the tire size I've chosen is the 33x10.5R15 in a BFG A/T. I too like the taller look of the early 4x's. Jimm1009's comment served as some serious validation since I too like a slower turning diesel at hwy speeds and the tires were already ordered through Tire Rack. Their wholesale price for 5 tires delivered is right at $800. Not too terribly bad for a nice tire in my opinion.

Next I'll try to find the missing shackles (x4), some new shocks (black Bilsteins??), and external tire carrier.

I'll post some photos when they're all installed and I'm back on the road again. Thanks again for everyone's help.

Hey, that's the exact set-up I went with. Good tire choice IMHO!

I like BFG A/T 33 x 10.5 R15 too. Exactly the same tires I have on my M1009!! I love them. But I paid $1300 for them, (installed on rims and balanced, I put them on the truck). Stupid Canadian gov.. everything is expensive up here. Another reason 10.5" width is great, is less surface area of tire on the road. That helps you stick to ice. Not that most posters here have ice problems lol.

I put 33x12.5x15 on one of my M1009s.

I had some rubbing on the front inside fender on the passenger side. I ended up trimming the inside fender to alleviate the condition. This post suggests the same cut I made.

I still haven't gotten around to installing my 1" zero rates. One day soon I will get the time. I need to source some new ubolts first.

Weak suspension and battery weight DOES cause the front passenger side to sag on the M1009s. Driver side on my truck is fine...only rubbing was on the passenger side.

I believe you have it backwards about the ice. The more surface area you have on ice the better you will stick the more pressure you get on the ice creates the thin film of water that makes for sliding. Thats why ice skates work.
As for tires, I like a narrower taller tire so you can fit a taller tire before rubbing and there is less drag or friction on the road. I went with 16" wheels. More truck tire sizes in 16". The bad is they are not common in 6 lug with the required back spacing. The ones I have found me while I was getting fuel. A guy came up to me and said I have some wheels and tires that will fit your truck and a deal was struck.
The question I have is in a emergency stop with a vehicle of the M1009's weight considering surface area of the tires footprint and pressure on the road(not air) which goes up as the footprint gets smaller what tire size will give the shortest stop considering tire compounds are the same? Is it the wider you get the better it gets or is there a point where pressure on the road comes into play on asphalt. What do you guys think?

 

[rhinob]

Winter tires (read: Ice and snow) are actually narrower than standard summer all-season tires. Bought many through the years. When you order the same exact size tire you have, the winter tire will be physically narrower with less surface / contact point area and higher surface pressure.

 

[rhinob]

Alright. Tires purchased and installed. As promised, the photos. Thanks to all...

Looks great, if i were to buy new tires i would go that size. Craigslist was good to me, so i have the 33x12.5's.

 

[2deuce]

What you don't want on ice is a higher surface pressure. I don't think a small increase or decrease will make any difference, but the more contact you have the better. You will notice that if the ice is very cold, traction is improved, the water that is created by the pressure doesn't form so easily, it takes more pressure to create the film of water. That is what an ice skater slides on, the film of water between the skate and the ice. The pressure that is created from the skaters weight is concentrated under the blade. Thats also why ice at the freezing point is the slickest.

From Tire Rack....


Priorities for Sizing Winter Tires Are Different

Does your sports car, coupe or sedan use wide, low profile tires that are mounted on large diameter wheels? Or does your light truck use large flotation-sized tires? If you're going to drive through lots of snow this year you'll want your winter tires and wheels in sizes that help put the laws of physics on your side.
A wide, low profile or large tire has to "plow" a wide path through snow which causes more resistance. The narrower the tire, the easier you can get through snow. We'll help verify sufficient load capacity and the appropriate diameter for your vehicle when you speak with one of our sales specialists or use Winter Shop by Vehicle.

This doesn't specifically address ice, however.



If I measure both types of my 235/55/R17's on my S350 diesel, the winter tires are a full inch narrower than the summer tires. Same for my Land Rover Discovery Blizzaks vs. Michelins.


Some of these things can be counter intuitive. Personally I prefer to keep the cars looking the same and buy the next wider tire, which they've always recommended against.

 

[2deuce]

With snow you don't want flotation, you want to get down to the traction. I was speaking of ice. That being said if you want to break through a drift you might want some flotation so you don't get high centered. I just made a comment about ice and tire footprint, what you really need are studs for grip. There is a guy out here that is pioneering retractible studs that work off air pressure.

 

[rhinob]

Right. Information on "ice" is elusive. Googled the **** out of it and could only find opinions on the snow aspect of winter tires. The one thing interesting about the compound of winter tires is the bubble-gum flexibility of the rubber. Amazing they don't peel off the rim in 3 miles, but I've had great luck with using them through the years.

Retractable studs? That would be amazing. And absolutely studs are the best way to secure the tire to the ice but unfortunately they're not legal in every state.

Big business isn't supportive of his idea. If fact I think they try to hinder, last I heard he had a tire manufacturer in china ready to produce them. He is a minister and not in it for the money, at least for himself. He has had a roadblock around every corner.

Good Evening! Have found the Chev. Manuals. Only one missing is the operators.
Give me a call if you are interested. These cover all levals of military repair.

Great CW. I'll give you a call....

 

[chrisknight_1985]

Ok, i so lost. The 33X12.50R15 will fit on the m1009 with stock rims and no rubbing. I dont wanna have to cut anything, and trying to stay away from putting a lift. I also want to put the bigest tire i can.

 

[jdeoliveira74]

33x10.5x15 is biggest the 12.5 will rub slightly is what i got from this!

 

[designerRob]

Alright. Tires purchased and installed. As promised, the photos. Thanks to all...

Nice choice. Those BFG A/T's will last you a long time.
