- ETS here means Basic Earthmover Tire Service, a 200-level Certificate of Completion administered by the Tire Industry Association (TIA).
- The scope is defined by 15 unweighted official modules, not a percentage-weighted blueprint.
- Training runs through TIA Online University or in-person kits with videos, workbooks, and paper exams.
- Basic ETS and Basic CTS are prerequisites for the separate Certified ETS 300/400 pathway, which is outside this scope.
What Does ETS Mean?
In the off-road tire world, ETS stands for Earthmover Tire Service. Specifically, this article covers Basic ETS, a 200-level Certificate of Completion developed and administered by the Tire Industry Association (TIA). It is not a generic acronym you can borrow meaning for from another industry - inside TIA's training system, ETS refers strictly to the curriculum that teaches technicians how to safely mount, dismount, service, and inspect earthmover and off-the-road (OTR) tire and rim assemblies.
If you landed here searching for a broader definition, it helps to start with the fundamentals in What Is ETS? and What Does ETS Stand For?, which walk through the terminology before diving into exam mechanics. This piece focuses specifically on unpacking the meaning behind the letters and what that meaning implies for someone preparing to sit the Basic ETS final exam.
Who Administers Basic ETS?
TIA is the governing and administering body for Basic ETS. Training materials, module lists, and the final exam all originate from TIA, and the credential sits at the 200 level within TIA's broader technician training series. This matters because the "ETS" acronym appears attached to other credentialing programs in unrelated fields - but within the scope of this site and this exam, every fact traces back to TIA's published Basic ETS materials.
Because TIA structures its training in tiers, understanding where Basic ETS sits helps frame expectations. For a full breakdown of eligibility and how candidates qualify for training, see ETS Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The 15 Modules That Define ETS
Rather than a weighted exam blueprint with percentage breakdowns per topic, Basic ETS is defined by 15 unweighted official modules. These modules function as the course and exam scope simultaneously - there is no separate published domain-weighting document, so every module deserves a technician's full attention rather than being triaged by an assumed point value.
Domain 1: Introduction
Establishes foundational vocabulary and safety orientation before hands-on modules begin.
- Sets expectations for the rest of the course
Domain 2: Tires, Rims & Valves
Covers the physical components technicians will handle constantly - construction differences, rim types, and valve assemblies.
- Know the anatomy before touching equipment
Domain 3: Service Truck Operation
Focuses on safe operation of the mobile service truck used to reach earthmover equipment in the field.
- Truck setup and positioning fundamentals
Domain 4: Site Preparation & Equipment Lifting
Addresses how to prepare a work site around heavy machinery and the lifting procedures required before service begins.
- Ground stability and lift-point awareness
Domain 5: Hydraulic Bead Breakers & Rams
Covers the hydraulic tools technicians rely on to break beads on massive OTR tires safely.
- Tool setup, pressure control, and pinch-point hazards
Modules 6 through 12 form the technical core of the course, walking through service procedures across different rim assembly types, both while the tire remains on the machine and while it is removed:
Domains 6-9: On-Machine Service
These four modules - Service One-Piece on Machine, Service Three-Piece on Machine, Service Five-Piece on Machine, and Service Double Gutter on Machine - teach procedures for servicing assemblies without removing the wheel from the equipment.
- Recognize assembly type before selecting a procedure
- Understand how gutter design changes the servicing steps
Domains 10-12: Loose Assembly Service
Service One-Piece Loose, Service Three-Piece Loose, and Service Five-Piece Loose mirror the on-machine modules but apply once the assembly has been removed from the equipment for bench-style servicing.
- Contrast on-machine vs. loose procedures for the same rim type
- Expect exam questions that test whether you can tell the two contexts apart
Domain 13: Wheel & Rim Fastening Systems
Covers the hardware - nuts, studs, clamps - that secures wheels and rims, along with correct fastening sequences.
- Torque and sequence awareness
Domains 14-15: Install & Remove Fitment
Install & Remove Wheel Fitment and Install and Remove Rim Fitment close out the course by testing whether a technician can correctly match wheels and rims to equipment during final installation.
- Fitment errors are a common source of field failures
For a deeper module-by-module walkthrough with study strategies tied to each area, see ETS Exam Domains 2026: Complete Guide to All 15 Content Areas. Because there's no published weighting, candidates preparing for the final exam often ask how difficult each section feels in practice - that question is addressed directly in How Hard Is the ETS Exam? Complete Difficulty Guide 2026.
Key Takeaway
Since the 15 modules are unweighted, don't assume any single domain is "worth less" on the final exam. Study Domain 1 (Introduction) with the same seriousness as the hands-on service modules.
Format, Fees, and Training Mechanics
Basic ETS training is delivered two ways: through TIA Online University or in person using DVDs, workbooks, and paper exams. The Online University path is self-paced and includes videos, knowledge checks, a final exam, and a skills-demonstration form, with administrators able to monitor technician progress and results - useful for shops tracking multiple trainees at once.
One frequently misunderstood detail: the brochure references a three-hour video duration, but that is a runtime for the training content, not a time limit imposed on the final exam itself. Don't confuse the two when planning your study schedule.
| Item | Price (Member) | Price (Non-Member) |
|---|---|---|
| Basic ETS kit (2 DVDs, 1 workbook, 1 test booklet) | $995 | $1,995 |
| Student workbook + test booklet (qty 1-9) | $95/copy | $195/copy |
| Additional test booklet only (qty 1-9) | $75/copy | $175/copy |
| Online University access (with certificates) | $305 per location/year + $20 membership fee | |
| Online University access (without certificates) | $155 per location/year + $20 membership fee | |
Shipping and handling are additional on physical kits, and the Online University pricing requires full headquarters membership. These are training-material and subscription prices rather than a per-candidate exam registration fee, and they allow unlimited technicians at each subscribed location. For a full pricing walkthrough with context on which option fits which shop size, read ETS Certification Cost 2026: Complete Pricing Breakdown.

Who Actually Needs This Credential?
Basic-level training is designed for new-hire orientation and for experienced technicians who need documented training on their record. In practice, this means the credential is aimed at two groups: technicians just entering OTR tire service roles, and veteran techs whose employer needs a paper trail proving formal instruction occurred.
There's an added wrinkle for technicians working under MSHA Part 46 rules. 30 CFR 46.8 requires at least eight hours of annual refresher training for covered miners, and TIA frames its refresher instruction (followed by testing) as a path to an updated Certificate of Completion and wallet ID card. That refresher cycle is specific to the mine-safety context - it is not evidence of a universal Basic ETS expiration date or a CEU requirement applying to every certificate holder.
Employers hiring for this kind of work range from OTR tire dealers and mining operations to heavy equipment service fleets. If you're weighing whether pursuing the credential makes sense for your career path, Is the ETS Certification Worth It? Complete ROI Analysis 2026 and ETS Salary Guide 2026: Complete Earnings Analysis lay out the considerations - including how broad occupational wage data (like BLS figures for tire repairers and changers generally) relates, or doesn't directly relate, to OTR-specific roles. For where these roles get posted, see ETS Jobs.
Basic ETS vs. Certified ETS 300/400
A common point of confusion is treating "ETS" as one single credential. It isn't. Basic ETS is the 200-level program covered throughout this article. Separate from it is Certified ETS 300/400, a distinct pathway intended for experienced OTR technicians. Basic CTS and Basic ETS both serve as prerequisites for that advanced pathway, but the 300/400 tier carries its own two-year online recertification rule - a rule that does not apply back down to the Basic ETS scope described here.
If your goal is simply to understand or prepare for the Basic-level Certificate of Completion, you can safely set the 300/400 recertification details aside; they belong to a different stage of a technician's career progression. For a plain-language overview of how these pieces fit together, ETS Certification and What Is ETS Certification? cover the distinction in more depth, and What Is A ETS? addresses the terminology question from another angle for readers arriving with slightly different search phrasing.
Mapping Study Time to Modules
Because Basic ETS content is delivered through videos, workbooks, and knowledge checks rather than a single dense reading, a practical study rhythm treats each cluster of modules as its own study block instead of cramming all 15 at once.
Foundations
- Domain 1: Introduction
- Domain 2: Tires, Rims & Valves
- Domain 3: Service Truck Operation
Site Setup & Tools
- Domain 4: Site Preparation & Equipment Lifting
- Domain 5: Hydraulic Bead Breakers & Rams
On-Machine Service
- Domains 6-9: One-Piece, Three-Piece, Five-Piece, Double Gutter on Machine
Loose Assembly & Fastening
- Domains 10-12: Loose assembly service
- Domain 13: Wheel & Rim Fastening Systems
Fitment & Review
- Domains 14-15: Install & Remove Wheel/Rim Fitment
- Full run-through of knowledge checks and skills-demonstration form
Notice how weeks 3 and 4 deliberately pair on-machine and loose-assembly modules for the same rim type in adjacent study sessions - that contrast is exactly where exam questions tend to probe whether a candidate can tell procedures apart. A structured plan like this, paired with realistic practice questions on our practice test site, tends to work better than passive re-watching of course videos. For a more detailed week-by-week breakdown with additional tactics, see ETS Study Guide 2026: How to Pass on Your First Attempt, and keep a condensed reference nearby using the ETS Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Key Takeaway
Group study sessions by module cluster (on-machine vs. loose, for example) rather than studying strictly in numerical order - the contrasts are where most confusion happens on exam day.
Frequently Asked Questions
Earthmover Tire Service. Specifically, this article covers Basic ETS, the 200-level Certificate of Completion administered by the Tire Industry Association.
The reviewed official TIA source does not publish a separate exam code, question count, or time limit for Basic ETS. The three-hour figure sometimes seen refers to brochure video runtime, not exam duration.
There is no universal Basic ETS expiration or CEU cycle described in TIA's materials. A separate eight-hour annual refresher applies specifically to miners covered under MSHA Part 46, and a distinct two-year recertification rule applies only to the separate Certified ETS 300/400 pathway.
Basic ETS is the 200-level, exam-backed Certificate of Completion covering 15 foundational modules. Certified ETS 300/400 is a separate, more advanced pathway intended for experienced OTR technicians, for which Basic ETS and Basic CTS serve as prerequisites.
