- CCTS is the Certified Commercial Tire Service Instructor credential from the Tire Industry Association (TIA), confirmed by O*NET.
- Current registration lists $950 for a four-day instructor training and certification bundle - not an exam-only fee.
- Candidates need a passing final exam plus witnessed, signed-off practical shop skills; written practice alone doesn't certify you.
- TIA lists 19 course modules, from Introduction through USTMA Guidelines, but no official weighting is published.
What CCTS Actually Stands For
Before anything else, lock in the identity so you're not studying the wrong material: CCTS here means Certified Commercial Tire Service Instructor, a credential administered by the Tire Industry Association (TIA). The official course wording on TIA's own materials calls it "Certified CTS Instructor, 400 Level," and the CCTS acronym and job title are supported by O*NET's occupational data. If you've seen other "CCTS" acronyms floating around in other industries with different fees, exam vendors, or pass rates, those are unrelated credentials - none of that information applies here.
For a plain-language breakdown of the acronym and the role it certifies, see What Does CCTS Stand For? and CCTS Meaning. If you're still deciding whether this is the right credential path for your shop role, What Is CCTS Certification? covers the basics in more depth.
Core Program Facts at a Glance
This is the one-page core of the cheat sheet. Everything below is drawn directly from TIA's published materials - if a data point isn't here, it's currently unverified, and this article will say so rather than guess.
| Item | What's Confirmed |
|---|---|
| Certifying body | Tire Industry Association (TIA) |
| Official course title | Certified CTS Instructor, 400 Level |
| Registration fee | $950 (per form revised August 14, 2026) - covers four-day training and certification, not exam access alone |
| Member/non-member pricing split | Not published |
| Training schedule | Four days in-person attendance |
| Certification requirement | Passing final exam + witnessed, signed-off practical shop skills |
| Minimum experience | At least two years hands-on experience (per TIA program description) |
| Degree or classroom-hour requirement | None located |
| Recertification cycle | Every two years, online exam |
| CEU requirement | None published |
Key Takeaway
Treat the $950 figure as a training-plus-certification bundle, not a standalone exam fee - budgeting around it as "just an exam cost" will give you the wrong expectation. For a full cost breakdown, see CCTS Certification Cost 2026: Complete Pricing Breakdown.
The 19 Official Course Modules
TIA's Certified CTS Instructor program is built around 19 named course modules. These are published preparation topics from TIA's course listing - treat them as the subject-matter map for your study, not as a confirmed, weighted exam blueprint. No single module is identified as carrying more weight than another, and there's no public evidence of an exhaustive examination breakdown.
Domain 1: Introduction
Covers program orientation and workplace safety fundamentals. Note: the separate Intro CTS 100 and Basic CTS 200 curricula are excluded from this 400-level course - this module is a retained safety-focused introduction specific to the instructor track.
- General shop safety culture and orientation framing for instructor-level candidates
Domain 2-3: Tires & Rims, Wheels & Hubs
Foundational hardware knowledge - tire construction basics and the components (rims, wheels, hubs) that interact with them in commercial service settings.
- Component identification and function
Domain 4-6: OSHA Regulations, Road Service Safety, Jacking & Lifting / Lock-Out-Tag-Out
The regulatory and physical-safety backbone of the course. Because candidates are also instructors, expect emphasis on how to teach these procedures correctly, not just perform them.
- OSHA compliance points relevant to commercial tire service
- Lifting and lock-out/tag-out procedure sequencing
Domain 7-8: Tire/Wheel Inspection & RIST
Inspection protocol, including the RIST (Removal, Inspection, Service, Testing) sequence used across commercial tire service work.
- Step order and what each stage of RIST is checking for
Domain 9-11: Hub-Pilot, Stud-Pilot & Demountable Rim Service
Wheel-mounting system differences matter here - commercial trucks use multiple hub/wheel-attachment designs, and each has its own service sequence.
- Distinguishing hub-pilot from stud-pilot systems before servicing
Domain 12-15: Single Piece & Multi-Piece Demount/Mount and Inflation
The instructor brochure uses the label "Demount/Mount" for these two modules. This is the hands-on core most closely tied to the witnessed practical skills requirement - written knowledge of sequencing won't substitute for demonstrated technique.
- Single-piece wheel procedures versus multi-piece wheel procedures
- Correct inflation cage/restraint use during both
Domain 16-17: Balance & Run-Out, Repair
Covers balancing technique, run-out diagnosis, and repair scope/limits for commercial tires.
- When a repair is within acceptable limits versus requiring replacement
Domain 18-19: Charts & Tables, USTMA Guidelines
Reference-material literacy - reading load/inflation charts correctly and applying U.S. Tire Manufacturers Association (USTMA) guidance.
- Chart interpretation under realistic shop scenarios

Registration & Fee Mechanics
The current official registration form, revised August 14, 2026, lists a single $950 charge that bundles the four-day instructor training with certification itself - there is no documented path to sit the exam alone for a lower fee, and no published member versus non-member price tier. If you see a different fee structure quoted elsewhere, verify it against TIA's current form rather than trusting secondhand numbers.
Eligibility Checklist
TIA describes this program as designed for personnel who already have practical experience in the field - specifically, at least two years of hands-on experience. Beyond that baseline, there's no located requirement for a college degree, a separate minimum classroom-hour count, or a specific number of professional references.
- At least two years of hands-on commercial tire service experience
- No degree requirement identified
- No separate classroom-hour minimum published outside the four-day training schedule
- No reference-count requirement located

Exam Day: Verified vs. Unverified
This is where candidates most often get misled by content written for a different "CCTS." Here's what is actually confirmed about the assessment itself, and what isn't yet publicly documented.
| Element | Status |
|---|---|
| Who administers the initial exam | TIA course-administered; no external exam vendor identified |
| Total/scored/unscored question counts | Unverified |
| Time limit | Unverified - not the same as the four-day training schedule |
| Item format | Unverified |
| Numerical passing score | Unverified |
| Exam version/form | Unverified |
| Open-book, calculator, adaptive, or remote-proctoring rules | Unverified |
| Retake policy for initial exam | Unverified |
| Practical component | Confirmed - witnessed, signed-off shop skills required alongside the written final |
Key Takeaway
The four-day training timetable describes attendance, not exam duration - don't assume the exam itself runs anywhere near four days. Treat question counts, time limits, and passing-score numbers as open questions until TIA publishes them, and lean on CCTS Passing Score 2026: Exactly What You Need to Pass for the latest confirmed detail on that front.
Because so much of the exam's mechanics remain unverified, it's worth reading a broader difficulty assessment before you assume this will mirror a typical multiple-choice certification exam. How Hard Is the CCTS Exam? Complete Difficulty Guide 2026 walks through what the practical-skills requirement actually changes about your prep strategy. If you're weighing whether the time and $950 investment pays off for your career, Is the CCTS Certification Worth It? Complete ROI Analysis 2026 and CCTS Salary Guide 2026: Complete Earnings Analysis are useful companion reads.
Recertification Cycle
CCTS credential holders recertify every two years through an online exam. No separate continuing-education-unit (CEU) requirement has been published alongside this cycle, and the renewal fee along with the specific test specifications for the recert exam are currently unverified. Build a two-year reminder into your calendar regardless - losing track of the window is a common, avoidable mistake.
A Tight Review Plan Before Training
Because the four-day training session is dense and the certification outcome depends on both a final exam and a witnessed practical, the smartest use of your pre-training time is reinforcing the modules most tied to hands-on technique - not generic study tricks. Here's a simple structure that respects the course's actual shape.
Safety & Regulatory Foundations
- Review Introduction, OSHA Regulations, Road Service Safety, and Jacking & Lifting/Lock-Out-Tag-Out modules
- Focus on being able to explain - not just perform - these procedures, since you're training to teach them
Inspection & Wheel Systems
- Work through Tire/Wheel Inspection, RIST, Hub-Pilot, Stud-Pilot, and Demountable Rim Service
- Practice distinguishing wheel-attachment systems from photos or real components, not just memorized labels
Demount/Mount & Inflation Practical Prep
- Drill Single Piece and Multi-Piece Demount/Mount plus Inflation procedures hands-on where possible
- This is the area most directly assessed by the witnessed practical component
Balance, Repair & Reference Materials
- Cover Balance & Run-Out, Repair, Charts & Tables, and USTMA Guidelines
- Run a full practice session using our CCTS practice test platform to pressure-test recall across all 19 modules before training week
