best overall 8.8 gear

^hm. yea, now that makes a lot of sense. but like i said before i got my speed covered already. but anyway, just for fun, what about 4.88's? or 5.13's or beyond?

Subscribing...also, got any pics of your truck NOT sunk in the mud?

Now you'll be going the other extreme. and you'll be winding out if you go highway driving. Usually I reserve 4.88's for 37-40" tires.

More and more power but less and less fuel milage.

Well yeah, cuz he'll run out of engine...OP, cruising down the highway at 3200rpm isn't that great of an idea. Unnecessary engine wear and there comes a point where the benefits are negligible or start doing more harm than good. Rule of thumb, you want to be under 2600rpm at cruising speed.

just throwing this out there. my rpm with 35-13.5-15 toyoz+3.55's = was about 2230, at 65

That seems a little high especially with an OD tranny.

 

[odogf150]

are you serious? it feels normal for the specs of my truck. but when i first got it the idle was way up, 2600. now it idles at about 900-1000 on start up then drops to about 500 or a little more. (cant tell anymore though, my tach broke)

 

[5.0Flareside]

i need to get a tach..... i wanna see what kinds of rpms im turnin haulin *** down the interstate.

 

[73F100Shortbed]

I'm at 2500rpms doing like 60 or so. I don't have a speedometer so I'm just guessing. It's rather annoying.

 

[odogf150]

yea. but has anyone considered the gear ratio helper thingamagig on the super swamper interco website? it seems helpful. original size 29.5 to 35 im going to get the gears before the end of the month.

The only way that would happen is in Drive which is a 1:1 ratio. The other issue though is if you haven't recalibrated your speedo for those tires you're actually doing 80mph when the speedo says 65.

There was a speed-table on the back cover of every timetable.
The Hoghead couldn't blame speeding on the speedometer or something.

no. its the right speed. i use a gps mounted on the window and it ALWAYS tells it right.

^ thats what i meant when i typed i have the speedo issue covered.

No you don't have it covered, the speedo has a much more important role than informing the driver how fast he is going. The computer uses the speed input signal to determine how the transmission is controlled so it is very important to the operation and life of the trans to have a functioning and accurate speedo.
The odometer is also driven off this signal and it too reads low when bigger tires are installed and that makes fuel milage look worse than it actually is because the vehicle is travelling further than the odometer indicates.
So say for example you get what appears to be 175mi out of a tank with your 35's, that's about 9.7mpg. Problem is you have actually gone 218mi so your real milage is 12mpg.

i dont know about that. my mileage is on. i did a test yesterday so, i dont know maybe the guy before me redid it.
