AxleSlide app

A truck weight calculator for semi trucks and tandem axle sliding.

AxleSlide helps truck drivers quickly calculate tandem axle adjustments and estimate truck weight distribution. Enter steer, drive, and trailer axle weights, select the current tandem position, choose a balancing strategy, and get an instant recommendation showing how many holes to move and in which direction.

Use it at a CAT Scale or while planning ahead. AxleSlide estimates weight transfer between drive and trailer axles, shows predicted axle weights after sliding, supports target balance, maximize trailer weight, and fewest legal holes modes, and includes safety indicators for legal limits.

Important: AxleSlide provides estimated results only. Always verify final weights at a certified scale and follow federal, state, local, bridge law, and jurisdiction-specific requirements.
