tire-safetyPrint a Sign-In Sheet | Spanish Version

A Miner Should Always:

  1. Check tires and rims.
    • Prior to mounting for damage or defects.
    • After mounting to see if they are properly seated.
    • Inspect the flange and side ring to make sure they are correctly positioned.
  2. Inspect all clamps and wheel nuts.
    • For wheel vibration due to loose nuts.
    • For loose clamps that can cause rim slippage or detachment of the rim and tire from the vehicle.
  3. Replace all damaged or weak parts.
    • Check for metal cracks, dents, and signs of metal fatigue.
  4. Check for-
    • Excessive ring butting and side ring play.
    • Mismatched rim parts.
  5. Replace all severely rusted rims.
    • Check all rims for excessive corrosion which could cause weakness.
    • Check for proper fitting of all rings due to potential build up of rust.
  6. Inflate all tires in a safety cage.
    • To prevent injury from a flying piece of metal due to a weak rim part.
    • To prevent injury from a flying ring.
  7. Deflate tires prior to demounting.
    • Check for damage to rim and rings.
    • Check for an unseated ring.
    • Remove the tire by deflating it first, if the ring appears to be unseated.
    • Remove the valve core to ensure complete deflation.

A Miner Should Never:

  1. Work carelessly.
    • Always follow standard operating procedures for a given tire and rim task.
  2. Take unnecessary chances.
    • Always be sure of the proper procedure of mating rim and wheel parts.
    • Always ask questions of a more knowledgeable miner or distributor if there is a question regarding a certain tire and rim procedure.
  3. Operate a vehicle on a single tire of a dual assembly.
    • Always inflate both tires to recommended balanced pressures before operating the vehicle.
    • Always check the capacity of each tire to determine if it is being exceeded.
  4. Exceed the load rating of the tires.
    • Always make sure rims are not cracked or out-of-round.
    • Always increase the tire ply rating or size, or both, if the vehicle is to have excessive heavy loads.
    • Always use correct size rims for certain tire sizes.
    • Always stay within the specific tire pressure.
  5. Use undersized tires.
    • Always check for chafing, pinching, and premature failure of rim due to under sizing.
    • Always check for bead or sidewall failure of the tire.
  6. Take one manufacturer’s rims and mix with another manufacturer’s rims.
    • Always match components parts and rims by make, size, and type.
  7. Take a flat tire and reinflate it without first carefully inspecting the complete tire, wheel assembly, and rim for unsafe conditions.
    • Always inspect the ring for potential damage and make certain it is secure in the gutter before inflation.
