About this app

Trucker's Slide Calc just got better!
- User interface redesigned and rewritten for a better experience with less bugs.
- Slide suggestions are more standardized.
- Users can now set an "allowable overage" weight. For example, if an overage of 100 lbs is allowed, a 34,000 lb limited axle can weigh 34,100 lbs when we calculate the suggestion.
- Users who pay to remove ads are now "Plus" users.
- Plus users can now choose to maximize trailer weight. Great for heavy, fuel-limiting, loads or improving turn radius.

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.

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.

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!

Mostly good. Once in a while it will give a bad calculation. One thing it's lacking is the ability to accommodate for scales that are not zeroed out. For example... You approach a scale and notice that it does not read 0 pounds as it should. Instead, It may read 820 pounds or -1240 pounds. This forces you to manually do all the calculations yourself. In the app there should be a way to input what the scale is reading before you drive onto it and then adjust, and calculate everything correctly.

Awesome interface. Originally when I input the scale numbers from the cat scale ticket the response the app gave was incorrect. I would rescale and receive a different read out. I gave this app another try since the most recent update, and I must say that I enjoy the new interface, along with proper instructions of where to slide my tandems. Thanks Semis...

Great app to use if you struggle with the concept of figuring it out manually. The app is very accurate if you enter accurate info. Some ads but they're not annoyingly in the way constantly. Great app! Cuts out the guess work and trial, weigh, error, try again, weigh again. Move once, reweigh, off you go.
