395s WILL fit on a stock Deuce!!!

[sermis]

I have been running 395's for a couple years. I added 3" to my stock rims which kept the sidewall from bulging. I never could get the ring on the stock rim w/o pinching the tube. I noticed a power loss. On flat ground the truck would haul A** but pulling any grade it would loose power. Fuel was turned up.
I have serious power loss not to the point I can't hardly get out of 3rd. Maybe it was my motor or the extra pull caused the motor problems. I am also running 395's on a bob truck and no power problem on that truck.

welcome to 2006!!

your tires are the same size as 15.5/80 R20's.
the deuce as a 48" spread between rear axles. so the 14.00's will not fit

here are some pics of mine. I have ripped my J pipe apart from off road articulation. I have not notice it the rear hits the bed. I don't think so.

These tires are great for offroad use. I have been using them for several years. I don't spend much time on road so I have no comments about that.

Who won rizzo?

 

[OPCOM]

OD Iron has 1-piece tubeless rims for those tires. There is also another vendor, forget whom. There was discussion about the ballooning of the tires on the stock rims, one guy said he ran them offroad for mudding but didn't think much of trying this onthe highway.

The 395 (46") is the biggest you can put on a 6 wheeled truck. If you bob it, you can run 14.00s pretty easily, and 16.00s with a little modding.

Depends on the aspect ratio of the tire, 395 with 100% aspect ratio would be 52 inches in dia. 395/85 is 47.5 inches in dia and 395/80 is 45.75 in dia by calculation.

the 1100-20 is 42 inches in dia since it's a 100% aspect ratio tire as is the 14.00-20, which is 48 inches in dia by calculation.

1 inch = 24.5 mm

My 1600-20 tires on the 8x8 are 70% aspect ratio and about 43 inches in dia.

Correct me if I'm wrong.

The 395 (16 inches), 14, 11 or 16 number is the width in all cases.

cranetruck, what does the 1100 part of "1100-20" signify? If it's millimeters then:

1100 (100%) divided by 24.5 = 44.90"
14.00 (decimal??) (100%) divided by 24.5 = 57.14"
1600 (70%) divided by 24.5 = 45.71"

It appears I don't know what 1100, 14.00 and 1600 mean. Would you please direct me to a resource where I can learn more about tire sizing?

Thanks,

Rick

Who won rizzo?

the monster truck. I heard he was 15k. he had 5 tons with planetary hubs

There was another vendor.

I think Dave at Eastern Surplus has them

11.00 is the distance from the rim to the outside of the tire. easy to figure diameter of a tire 11 + 20 + 11 = 42

Re: different tire/wheel widths, I run 325/85/16 XMLs (38" tall, 13" wide) on my '88 Blazer and '95 Dodge. 7" or 8" wide wheels on the blazer and 10" on the Dodge. I beat the wee outta them, offroading on rocks, etc. at low pressures, and I'm not gentle as I should be with the throttle, as evidenced by my pile of broken front axle shafts.

The dodge weighs 7000# and has an 400hp/800 lb/ft Cummins. No problems except the tires "burp" air on the steering axle on the 10" wheels on the Dodge at single digit pressures sometimes (I rarely go that low, usually 10-15 psi).
On the narrow wheels on the lighter blazer, no problems except they will wear faster in the center with a lot of street use. Also, a narrow wheel not only sucks a tire in and makes it narrower, it makes it a bit shorter too.

I put 10" wheels on the Dodge because it does lots of street as well as offroad. The narrow wheels on the blazer felt fine, but kinda "squishy" in turns on the Dodge, normal wide tire on narrow wheel effect.

In short, I would think the wider tires on the narrower stock wheels on the deuce would be fine, except maybe with heavy loads at high speeds = stupidity.

Interesting. So if the decimal is missing, it is then assumed. Got it, thanks.

I breezed through the thread and didn't see anything about the questions about the load on the bearings with the hubs not flipped or using the proper offset on the rims. I don't mean it can't be done, I just think the ODiron rims with the more neutrall offset would help bearing life?

Ditto

 

[gimpyrobb]

To answer the bearing question, it may be BETTER for them, but only marginally. If you search 395/85r20, some guys have run these for quite sometime with no problems. I have had mine on for a small amount of time, but have had many miles and atleast 5ton in the bed with no problems or hot hubs yet.

 

[thirdstreettito]

Whats the cost on those tires?

 

[100dollarman]

Whats the cost on those tires?

$150 each

 

[tm america]

i got mine for 100 each 90 to 100% tread

 

[thirdstreettito]

Where do you buy them from?

 

[cranetruck]

I have six used ones...PM me for info.

 

[DavidWymore]

What does better in sand/mud = flotation? Duals or 395s?

 

[tm america]

395s or 15.5 do way better in the mud ,snow rain and sand since youre not running duals in the front 395s are best for the mud but wear kind of fast on the street .rain and snow the 15.5s do awsome

 

[OPCOM]

Do they wear as fast as 11.00x20's? My 11.00x20's have gone some 15000 miles and still OK. When I had 9.00x20's, the fronts wore quite fast.

Aftermarket wheels have an offset that splits the diference for non-flipped or flipped hubs, therefore making a better track between front and rear. I am not comfy with a stock offset and one wheel on the rear axle "dish out", and I'm too lazy to flip the hubs. But I do PM.

The 11.00z20 will take you from 56MPH to 59MPH. Means easy cruising at 55.
The 395/85R20 will take you from 56MPH to 64MPH. Means easy cruising at 60.

note to self; if i ever go from ten to six wheels, cary a spare..
