1. Axle Weight Limits in New York

New York enforces axle weight limits based on the number of axles and their spacing, following federal guidelines and the Federal Bridge Formula.

Standard Axle Limits (Permit-Free):

  • Single Axle: 20,000 lbs

  • Tandem Axle: 34,000 lbs

  • Tridem Axle: 51,000 lbs

Tip: Exceeding these limits requires a special overweight or oversize permit.

Notes:

  • Axle spacing affects maximum allowable weight.

  • Overweight loads must comply with route restrictions to protect bridges and roadways.

2. Tire Regulations in New York

Tire regulations ensure load-bearing capacity and road safety:

  1. Tire Size & Load Rating:

    • Commercial vehicles must use tires that support the weight of each axle.

    • Tire load rating must meet or exceed the actual axle weight.

  2. Tire Condition Requirements:

    • Tires must have minimum tread depth (generally 4/32” for steer tires, 2/32” for others).

    • No visible cords, cuts, or excessive wear.

  3. Dual Tires on Tandem Axles:

    • Tires must be properly inflated and aligned to carry the designated load.

3. Combined Vehicle Weight & Tire Compliance

  • Axle weight + tire capacity = safe operation

  • Trucking companies must verify weight distribution for loaded trailers.

  • Non-compliance may result in fines, vehicle out-of-service orders, and permit revocation.

4. Special Considerations

  1. Oversize & Overweight Loads:

    • Must obtain special permits from NYSDOT or NYS Thruway Authority.

    • Route selection may be restricted based on bridge weight limits.

  2. Inspection Requirements:

    • Commercial vehicles are subject to periodic inspections by NYS DOT and law enforcement.

    • Tires and axles are common inspection points.

  3. Seasonal Restrictions:

    • Weight limits may be reduced during spring thaw to protect roads and bridges.

5. Compliance Tips for NY Truckers

  • Always check axle weight distribution before departure.

  • Use proper tires rated for load and maintain correct inflation.

  • Obtain permits if weight exceeds legal limits.

  • Carry proof of tire ratings and axle weights for inspections.
