## What is Trucker's Slide Calc?

DESCRIPTION & OPERATION
Enter your axle weights (platform scale or individual axles) and the app calculates how much each axle is over or under, including gross. Then click to get a suggestions and it tells you where to slide. It's that easy.

Hole #1 is the hole closest to the front of the trailer. Then count up as you move backwards towards the tandem axle's first pin.

HOW DOES IT WORK?
Trucker's Slide Calc uses a computer algorithm to simulate your axle weights at each hole. It then picks the best hole for the situation.

Having Drives and Trailers balanced saves you fuel and money, so the app tries to do this first: putting slightly more weight on your drives for traction and fuel burn.

If equally balancing the axles makes an axle go over limit, the app will elect to keep the axles legal but out of perfect balance.

Last, if every axle can't be legal at the same time, the app automatically suggests a hole where your trailers will be just under their limit, and puts the rest of the weight on your drives. That way you can remove the extra fuel and get legal before a DOT Scale.


SO HOW ACCURATE IS IT?
Here is a real-life example from one of our users: The driver got a load of onions on a 53' Refer Semi. He went to a CAT Scale, got the scale ticket, and entered the weights into the app...

1st CAT Scale: @ hole 4
Steers : 11,780
Drives: 32,480
Trailers: 35,160

Our axle slide calculator told him to slide forward 3 holes and go directly to hole 7. It estimated that his axles would then weigh...

Calculated Axle Weights: @ hole 7
Drives: 33,675
Trailers: 33,965

He slid his tandems to hole 7 and re-weighed his truck. The results made him excited enough to tell us his story...

2nd CAT Scale: @ hole 7
Steers: 11,800
Drives: 33,740
Trailers: 33,880

Only 65 lbs off on his Drives and 85 lbs off on his trailers. That's over 99.5% accuracy. Pretty awesome if you ask us! We truly believe that we have the best axle-weight calculator out there. And it's free!

Disclaimer: Bridge and Kingpin-to-Rear-Axle Laws are not considered in this application. Remember, even if you use this app, it is your responsibility to ensure that your load complies with all federal and local laws.

### 1/5 — paid but still get ads

*2026-08-26, version 1.0.3*

i paid for a year and i still get ads and if i have no connection it won't give me the calculations cause the ads won't load. Which is why i paid for the ad free version for a year and still don't have access to the app.

### 2/5 — Keeps requiring a purchase

*2026-08-22, version 1.0.3*

This app is ok. It does what I need it to do. But I’ve paid for the premium option multiple times and it continues to show adds unless I make ANOTHER purchase. And I cannot find an option to contact anyone 👎🏼👎🏼

### 5/5 — Les recomiendo

*2026-01-24, version 1.0.3*

Excelente aplicación fácil y práctica 10 de 10

### 1/5 — Ads

*2025-12-16, version 1.0.3*

Those ads are getting in the way of using your actual app. I don’t want to download it. I want to scale my loads. Normally a X pops up in the corner to close it out. It just freezes up.

### 1/5 — Ads have disabled app

*2025-11-12, version 1.0.3*

Here we are again-love the app, use it several times per day, paid the money to keep ads off, now ads are highjacking the main screen and cannot get past without pulling up the ad and dealing with it-very hard to get rid of or get out. Keep my freaking money, I am finding a new program!

### 1/5 — Used to work great

*2025-06-05, version 1.0.3*

It used to work great but in the last month or so it hasn’t been working at all it will give you completely wrong information by about 10000 or more pounds in either direction

### 1/5 — Only advertising

*2025-05-31, version 1.0.3*

App broken, work only advertising

### 1/5 — Can’t skip ad when ad is done. Thanks royal kingdom

*2025-05-20, version 1.0.3*

Title says it all

### 5/5 — Me

*2025-04-28, version 1.0.3*

NICE

### 1/5 — App doesn’t work anymore

*2025-04-27, version 1.0.3*

Used to be a good app . But now that adds have been added it no longer works. The app gets stuck in the add and you can’t get back to your axle’s weight .
