Took the 395s for a spin today

[gimpyrobb]

Didn't notice any power loss. It is bouncy though. WIsh I had that fuel line the "big green triple A" said they got me! This thing leaks like a sive.

And look at the cool pics! How much air in the tires?

 

[grounded]

glad to hear you got it together

 

[gimpyrobb]

Pics some time, 60 ish, I think. Should I go higher?

 

[sermis]

Less. I run about 35 before it got smooth.

 

[rockman]

I run about 40 in 12.5s. Try airing down until you find the best pressure.

Here's a few pics...

 

[tm america]

i run 35 in mine .pretty smooth at that

What fuel line? Who promised one and what kind of cover do you have on that thing?

 

[gimpyrobb]

The fuel line that goes under the radiator. It should be here in about an hour. Its an fmtv dump truck cover. It doesn't fit great, but its good enough. I took off the stock deuce cover, rasied the staves 11.75 inches and put it on, works pretty darn good.

 

[Recovry4x4]

Alrightythen. I was hoping it wasn't me that promised you the fuel line because the extra I have, I still have!

 

[Beerslayer]

It is bouncy though.

I had same issue. Discussion and a lot of help offered here:

Thanks Slayer, I had been following that thread. Like you, I lowered it to 40 and the ride improved. I will probably go down to 35.

I am thinking to go to 35 myself. Oh, you can call me BS if you like

Most do.

FYI RE: Tire pressure. I think I've posted this elsewhere, but...

I run 325/85/16 XMLs on my 7000# Cummins Dodge. I shouldn't admit this and you shouldn't try it at home, but I used to go out to the local desert, air down to 10-15 psi, go offroading, and drive it home, never with any issues. ON long trips where I want mileage I run about 40 psi, esp if loaded, more if loaded heavy. Around town I run anything from 20something to 30something. The ride a lot better the lower you go. I reckon a guy oughta do the math and figure out what pressure he should be at for the load he's got, but just to help with your peace of mind, these tires will take a fair bit of abuse. One side note though. It's my understanding that MV guys don't care much about date codes on tires. To me it is extremely important. I don't run anything more than a few years old. When aired down, they flex and come apart if they'e old.

This is an interesting thread.

I'm running 395X85R20 Michelins @ approx 90 PSI on my bobbed deuce and though they don't ride all that bad they seem to walk around a lot. I have to stay on top of the steering all the time. We've got the tow-in set at 1/4".

Given that I only weigh arount 10,300 lbs perhaps I should let some air out for better steering? I originally aired the tires up to the max for fuel economy.

Anyone got any suggestions. I'm not an off-roader

 

[gimpyrobb]

Ernie, what rims are your tires mounted on? I have mine on stockers and have the same trouble. I believe that it is because of the crown in the tire on rimm smaller than reccomended. I am working on fitting hemtt rims to my deuce.

 

[sermis]

I'm running about 35 on the bober with 10" wide rims. Ride is ok but it is like driving a 16' step ladder down the road. Thinking of going down another 5 to see if the walk will go away. 35 on the deuce seams about right.

That is way too much pressure, I can tell you that shooting from the hip.

Figure something like this - I"m no math whiz, or at least not good at explaining it. This sound right to yous guys?

For a rough example, mine are rated for 5000# @ 80psi. 80 div by 5000 = .016 psi per #. My truck weighs about 1750 per tire. So 1750 X .016 = 28 psi, which works out pretty good from experience. I usually run higheri n the front and lower in the back since the front is a little heavier and has steering duty.


Take a chalk line and mark across the tread of your tire. Then drive it a bit. See where the chalk wears off. Adjust pressure til you get even wear across the tread. This may not work if you have alot of crown, probably end up too low.

Another way is to air them up, then air down until you get just little bulge in the sidewall. Too low and it will feel bouncy and balloon like at higher speed.

When I got my dodge it had 37" SSRs. When they wore out I put 11.00 16 XZls on 6.5" wide wheels that I had run on my blazer on the dodge. It was wobbly on the freeway. I also tried 325/85/16 XMLs on 8" wheels, same problem. Now I have 325s on 10" wheels = very nice. The narrow wheels will help keep the beads seated at low psi offroad though and I had no problems with wobble on the lighter lower blazer. Wide tire + narrow wheel = not so good on the hiway. Wide wheel + narrow tire = unseated beads.

I ran 315/75/16 civvy tires (about 35x1250) on 7" wheels on my last dodge. The center of the tread wore out no matter what I did.

Went from 265s to 285s on one of our Super Dutys at work without going to a wider wheel and it got a bit wobbly at fwy speed.
