Title: Check tire matching (diameter and tread) on single and dual tire applications.
Course: Diesel Equipment Technology I (20107-I) > Section: Preventive Maintenance and Inspection: Servicing the Tires and Wheels

Checking should reflect understanding that tires of different dimensions should not be placed side by side. An exact version of the same tire, except new, should not be placed next to a worn tire. It is always better to replace both tires.

Process/Skill Questions:

- When placing a new tire next to a worn tire, which tire will carry the weight?
- When emergency stopping is required on a wet road, will mismatched tire sizes cause a danger?
