The manual gives one rule about mixing radial and non-radial tires on your vehicle. What does it say?

  1. A.
    Combine them only on the rear axle to protect steering
  2. B.
    Never combine radial and non-radial tires on the same vehicle Correct
  3. C.
    Combine them only during the studded-tire season
  4. D.
    Combine them only if both carry the same speed rating
The Why

The answer is "Never combine radial and non-radial tires on the same vehicle"

The manual makes it absolute: never combine radial and non-radial tires on the same vehicle. Drivers who reach for choice A assume the ban stops at the front axle because the steering tires feel like the critical pair, but the manual carves out no axle-based exception at all.

Why the others miss

The traps in the wrong answers

A. Combine them only on the rear axle to protect steering

This answer confines the ban to the front axle only. It borrows a general 'keep the steering tires matched' habit and treats the ban as if it stopped at the front axle.

C. Combine them only during the studded-tire season

This answer creates a seasonal exception the manual does not list. It blends the metal-stud calendar window with the separate rule against mixing tire constructions.

D. Combine them only if both carry the same speed rating

This answer softens the ban with a matching-speed condition. It reasons from a speed-rating pairing habit that applies inside one construction type, not across the ban on mixing constructions.
