22re, 1 tons, 43s, and 4.56?

Tire size? A 22re is OK when everything is stock, but still sluggish compared to.... well.... almost anything else.

This is magnified when used as a DD. This is coming from a guy who used to DD a 20r with 33s and 4.10.
 
I'm going to stop even telling you stuff...you don't listen anyway :flipoff2: It's going to suck and you'll never use 5th gear again.

1991 rpm at 65mph in 5th gear won't fly with all the weight and rotating mass you've added. The lack of torque and power in general is the killer. It'd be fine if you had a 5 speed with a Cummins in front of it, but nah....o_O At 65pmh in 4th gear, it'd be 2343 rpm.


You just need more power and 5.13s or 5.38s. There's not really a way around it.
 
I would say unbearably sluggish.
My truck has 22r, 4.88's and 35's. It's pretty damn sluggish. Add the weight of tons and 43's, I couldn't imagine how bad that would be.
 
I'm running 7.17 now and its overgeared horribly, going down US52 today to Oliver's I was running 65-70mph and tacking around 3700rpm. Could have gown much faster but I'm not risking blowing my motor up!
 
At 3700 rpm, you're going over 75 mph. Right at 78, according to the math.
 
The speedo being off isn't constant. At some point, it's reading slow. Somewhere in the spectrum, it's actually correct. Eventually, it reads fast.

You absolutely can NOT trust your speedometer. However, your tachometer and math don't lie. Gear ratios are constants.

Gear ratio x speed x 336 (a given constant) = a number
Divide that by the tire size
Multiply by .85 (that's your overdrive ratio)

This gives you an RPM at whatever speed you plugged in to start with while you're in 5th gear.

7.17 x 78 x 336 = 187,911.36
187,911.36 / 42.5 = 4,421.444
4,421.444 x .85 = 3758.23

So, again: 78 MPH, 5th gear, 42.5" tire gives you 3758 RPM.


Your tires are rated for 62 MPH :driver:

My 22re 4runner with 4.56 gears is sluggish enough with 35s that I run 33's on aluminum wheels till I go wheeling I am going to regear to 5.29 if you want 4.56 gears you better jump on the ls band wagon lol
 
I'm just going to say it: Needs more power. It's a slug in the stock truck, before handicapping it more with lots of rotating mass and big tires. It's about 105HP when it was new, right? Sloooow. :D

Tow it to the trail.
 
I have a 22re 4Runner on 38s with 5.13 and it's not bad but on highways you hit 5th on hills. Also have a truck 22re 4.88 with 38s and its the same deal. You will hate it. Now saying that we have drove many 22res with 38s and 40s on 4.10 it's possible to beat around but it sucks.
 
Didn't you gear the axles 7.17?

Why didn't you do the math before gearing them the lowest possible ratio?

Sound like you need to find your target rpm for the gear and work backwards to find the ratio you want. Stop guessing and throwing money away. Do the math, it's not that hard, and there are even online calculators you just enter your info in and it does the work.

I may be speaking incorrectly here, but think he geared them based on the 48s or 52s he had on it before.

Yeah I geared my truck based on the nearly 300lb michelins. Now my tires and wheels only weigh near 160ish

Gotya I apologize. I completely forgot about the larger tires before.

The diameter makes a larger difference than the overall weight.

Fwiw I'm running 42" sx2s with a 6cyl, with 5.38's and can run 70 mph no issue.

Making that comparison to a 4cyl I would think you would need to have either 5.86 or 6.17.
