Custom Test Solutions

For unusual or highly challenging test requests, Field Evaluation Services, Inc. develops tailored real-world solutions. Many custom programs are executed within TreadSight™ tire wear testing, while certain durability and impact services are delivered as standalone evaluations.

Custom real-world tire testing
Built around the mechanism. We excel when the test question is complex and the execution path is not immediately clear.

Two categories of custom programs

Custom programs fall into two clearly defined categories: TreadSight™ tire wear testing, which follows our cycle-based tread wear measurement framework, and non-tread durability, impact, or exposure testing, which addresses robustness, damage, or environmental exposure questions outside of tread wear evaluation.

  • TreadSight™ based custom wear programs
    Custom environments or mechanisms measured using structured tread wear methods.
  • Standalone durability & impact/pothole
    Bead/sidewall durability and impact/pothole simulation delivered outside the wear framework.
Data delivery approach

When custom programs fit best

  • Mechanism specific learning
    When the real-world mechanism is not captured by a standard route.
  • Challenging warranty / field issues
    When the objective is to replicate a failure mode or usage pattern defensibly.
  • Decision timing
    When program design must align with engineering schedules and milestone decisions.
Capabilities

Representative custom solutions

Below are common examples. Each program is scoped to the engineering question and can be executed at our facility or via Remote Support Units where road access allows (United States and Canada).

BB-4K bead and sidewall durability testing

BB-4K Bead / Sidewall Durability

Field Evaluation Services, Inc. is the only private company offering a Bead Trailer, known as BB1-4K. This custom-designed gooseneck trailer was engineered without a suspension, ensuring that all road impacts are absorbed by the tire, effectively testing the bead and sidewall performance for PCR, LTR, SUV, and STR tires. Additionally, STR tire tread wear and durability testing is available. Field Evaluation Services, Inc. offers trailers with load ranges from 5,000 to 14,000 lbs.

  • Load capability
    Loading up to 4,000 lbs. per wheel position.
  • Mechanism focus
    Bead/sidewall durability and impact related behavior.
  • Safety in mind
    CNC machined steel bars, providing substantial weight with a low center of gravity.
TIMCA7 impact and pothole simulation

TIMCA7 Impact & Pothole Simulation

Field Evaluation Services, Inc. designed and constructed a mobile, height adjustable curb specifically for impact and pothole simulation testing. Tires undergo shearography then sectioned as necessary for further analysis.

  • Configurable top block and height
    Selectable rounded or straight top block with adjustable height up to seven inches.
  • Digital documentation
    High speed video captures the impact.
  • Impact documentation
    Tires are marked in 45° segments and numbered, with paint strips being used to indicate impact locations.
Low speed high scrub wear testing

Low Speed High Scrub Wear Testing

Low speed high scrub testing conducted on a dedicated VDA pad in the Palm Springs area. When the objective is tread wear under high scrub conditions, this is measured using the TreadSight™ tire wear measurement framework (cycle based tread wear data).

  • TreadSight™ measurement
    Measured using a structured measurement book / framework (cycle based).
  • Application fit
    Used in programs targeting high scrub mechanisms (e.g., spread axle / refuse applications).
  • Engineering visibility
    Wear progression review across cycles rather than end of test.
Off-highway and mixed-surface tire wear testing

OHV / Off-Road & Mixed Surface Programs

We maintain access to a range of public and private use lands in Southern California for off highway vehicle (OHV) testing. When a program requires a specific region, Remote Support Units enable execution elsewhere in the United States or Canada where road.

  • Tread wear measurement
    Off-road wear programs can be measured and trended cycle by cycle.
  • Terrain variety
    Desert / wash / mixed terrain environments (program dependent).
  • Remote capable
    Programs can be provisioned with connectivity options when cellular coverage is limited.

Also available

Real-world component field evaluation

We also support real-world component field testing when the program objective goes beyond tread wear measurement. Programs are structured for traceability and engineering review under true service exposure.

  • In service reality
    Duty cycle, operating environment, and real exposure, not assumptions.
  • Independent reporting
    Documentation and defensible outputs suitable for engineering workflows.
Delivery

Data delivery built for real decisions

Wear programs preserve cycle based visibility; durability/impact services provide mechanism focused outputs. The scope is made explicit so engineering teams know exactly what the outputs represent.

  • Clear scope
    What is measured, and what the results mean.
  • Cycle updates
    Measurement cycle updates typically uploaded within hours of completed cycle.
  • Secure delivery
    Secure portal delivery aligned with engineering workflows.
