CDL · Vehicle inspection

As you look over the tires during a pre-trip inspection, which statement is accurate?

Correct answer: A vehicle should not be fitted with tires of different sizes.

Answer options

  1. AA vehicle should not be fitted with tires of different sizes. Correct
  2. BFront tires are safe with as little as 2/32 inch of tread.
  3. CIt is fine to put radial and bias-ply tires on the same axle.

Why

Tires of mismatched sizes are a defect to catch during the pre-trip inspection. Radial and bias-ply tires should not be used together, and front tires need at least 4/32 inch of tread in every major groove, so 2/32 inch is too little for them.
