Tire management in fleets of 50+: three pillars for scale

Managing tires in a fleet of 10 vehicles is one thing. With 50, 100 or 200, it is something completely different.

It is not just a matter of volume. Beyond a certain size, fleet tire management changes in nature. What worked with spreadsheets and visual control now requires a system, a structured process, indicators and a dedicated person. The cost of every mistake multiplies, but so does the return from every good practice.

Tires represent, on average, the third-largest operating cost of a road freight fleet, behind only fuel and maintenance. In well-managed fleets, this cost is around 8% to 12% of the total. In uncontrolled fleets, it can exceed 20%.

In Brazil, in an operation with more than 50 vehicles, the difference between these percentages easily represents hundreds of thousands of reais a year.

Let us now look at:

• What “ordinary” tire management is
• How tire management differs in a fleet of 50+ vehicles
• The pillars of tire management in fleets with 50+ motor vehicles

What is “ordinary” tire management?

Every road transport operation, regardless of fleet size, needs some level of control over its tires. In its most basic form, tire management comes down to two pillars:

1 – Tire identification (hot branding)

The fire number (the serial number branded on the tire) is the starting point for any control. It works like the tire's “CPF”, Brazil's individual taxpayer identification number: a unique identifier that allows that asset to be traced throughout its useful life.

Hot branding links each tire to a history, such as where it was fitted, how many kilometers it traveled, how many retreads it received and when it was discarded.

Without this identifier, you have tires. With it, you have traceable assets. It is the minimum foundation for any management, and most fleets, even small ones, already operate with this record.

2 – Controlling relocations, inventory and disposal

The second basic pillar is knowing where each tire is and where it has been. This involves recording incoming tires (purchases, returns from reconditioning), outgoing tires (fitting, sending for retreading), current position (which vehicle and axle) and disposal.

In small fleets, this control often happens in spreadsheets or even notebooks. It is laborious and prone to errors, but with few vehicles it is possible to maintain some visibility. The manager knows the fleet closely, knows which vehicles have more worn tires and can make decisions based on direct experience.

The issue is that this model has a ceiling. And it is reached quickly.

How does tire management differ in a truck fleet with 50+ motor vehicles?

When the fleet grows beyond 50 motor vehicles, complexity does not grow proportionally; it multiplies.

A fleet of 50 trucks may have between 500 and 700 active tires (including fitted tires and spares), plus inventory of new and reconditioned tires and those awaiting disposal. That is easily more than 1,000 assets to control.

At this scale, three elements cease to be optional and become structural:

1 – A dedicated person responsible for tire management

In smaller fleets, tire control is usually one of the many duties of the fleet manager or maintenance supervisor. From 50 vehicles onward, tire management demands someone whose focus is exclusive or, at a minimum, prioritized.

This professional ensures that inspections happen on time, rotations are carried out, inventory is organized, indicators are kept track of and anomalies are addressed before becoming losses. Without this person, control is spread across several people and ends up being no one's responsibility.

2 – A specialized tire management system

Spreadsheets do not scale. Beyond a certain volume, limitations appear in outdated data, lack of integration, typing errors, the inability to generate automatic indicators and the absence of real-time alerts.

A dedicated tire management system centralizes all relocations, automatically generates each asset's history, calculates indicators such as CPK, retreading rate and premature loss rate, and allows comparative analysis of makes, models, suppliers and vehicles.

This is how you move to data-based management, turning raw information into operational intelligence.

3 – A structured in-house tire workshop

Large fleets generally have their own tire workshop, for good reasons. This provides full control over processes, reduced downtime, the ability to maintain preventive routines and complete traceability for each service.

In this context, the in-house tire workshop is not a cost center; it is the operational base of tire management. It is where weekly calibration happens, tread depth inspection takes place, rotation is carried out and each relocation generates data.

These three elements (person, system and structure) form the three foundations supporting tire management in a large fleet. If any one is missing, the other two lose efficiency.

The pillars of tire management in fleets with 50+ motor vehicles

With these foundations structured, management needs to operate on specific pillars that address the challenges of scale. Let us look at each one:

The challenge of scale in tire management

The first point the manager of a large fleet needs to internalize is that scale changes everything. In Brazil, a mistake costing R$5 thousand per month in a fleet of 15 vehicles can cost R$30 thousand or more in a fleet of 100.

The same holds for benefits: a 5% improvement in average CPK in a fleet with 1,000 active tires generates savings that alone pay for investments in technology and the team.

Scale amplifies everything, good and bad alike. This is why large fleets cannot afford to operate with informal processes, manual controls or decisions based on individual experience.

Some specific challenges of scale are that:

• the volume of daily relocations makes reliable manual control impossible;
• the variety of vehicles and operations (different axles, loads, routes) requires more segmented management criteria;
• the team is larger, demanding rigorous standardization to maintain consistency;
• and investment in tires is substantial, requiring increasingly data-driven purchasing decisions.

Acquisition processes and product mix

In large fleets, tire purchasing shifts from a transaction to a strategy. Buying the cheapest make or the one you have “always used” is not enough. Volume gives you negotiating power, but also responsibility for the return on each real invested in Brazil.

The “engineering” of acquisition starts with a question: what is the actual CPK of each make and model you use? Without this data, any purchasing decision is based on sticker price rather than real value for money.

With structured data, you can compare the performance of different makes and models in your specific operation, already considering route type, load, road surface and usage conditions.

Just to give you an idea, a tire that costs 15% more but delivers 30% more mileage and accepts one additional retread is a better investment, even if it looks more expensive on the first invoice.

The product mix matters too. In diversified fleets with different vehicle and operation types, a single tire model is unlikely to serve everything well. The ideal mix (which makes and models for which axles and operations) should be reviewed periodically based on actual indicators, rather than tradition or personal preference.

Inventory management and tire storage

With more than 50 vehicles, tire inventory represents significant capital. In Brazil, a fleet of 100 vehicles may have between R$200 thousand and R$500 thousand in stored tires, including new and reconditioned tires and those awaiting disposition. This capital needs active management.

Good inventory control requires:

• clear physical separation between new, reconditioned and unserviceable tires, identified by type, size and status;
• FIFO (first in, first out) control to prevent degradation from time in storage;
• recording every incoming and outgoing tire in the system, without exception;
• and periodic inventory counts to compare physical inventory with system records.

But in large fleets, inventory requires more than organization. It needs planning. How much to buy, when to buy, minimum safety inventory by size and model, the supplier's lead time (total time between order and delivery), and how to absorb demand peaks without excess idle capital.

Well-managed inventory has the right tires at the right time, without waste. This is only possible with a certain level of automated tire management, with historical consumption data, demand predictability and replenishment alerts.

Reconditioning management: optimizing second and third lives

Retreading is one of the greatest drivers of savings in tire management. Each properly performed reconditioning costs between 30% and 40% of the price of a new tire and can deliver between 80% and 90% of its original mileage. In larger fleets, the difference between extracting 2 or 3 retreads per casing is enormous financially.

To achieve this, reconditioning management needs to be treated as a process. This means having objective criteria for sending tires for retreading, based on tread depth and casing condition. It means controlling how many lives each casing has had and the performance of each partner reconditioning company.

It is also essential to keep track of the casing rejection rate. If a high percentage of tires sent for reconditioning are rejected, this may indicate that tires are being sent too late (compromised casing) or that mechanical issues in vehicles are causing structural damage.

Performance analysis by reconditioning company (comparing CPK, durability and complaint rate) allows you to select the best partners and negotiate based on data rather than relationships.

Advanced KPIs and deviation analysis

In fleets with 50+ vehicles, management through indicators is a requirement, and the essential indicators are:

CPK (Cost per Kilometer):

This is the main and absolutely indispensable one. It divides the tire's total cost (purchase + reconditioning + repairs) by total mileage, allowing comparison of makes, models, suppliers and reconditioning companies on a common basis. It is the number that answers “was this tire worth the investment?”.

Retreading rate

This rate indicates how many lives, on average, you are extracting from each casing. If the average is below 2 retreads, there is waste, potentially caused by late dispatch, inadequate maintenance or mechanical issues.

Premature loss rate

This metric refers to the percentage of tires discarded before completing their expected useful life. Above 15% indicates systemic issues requiring investigation, and the most common causes include inadequate calibration, misalignment, overloading and operational damage.

Maintenance cost per event

Here, we mean the average cost of each repair, replacement or rotation. This indicator allows you to assess in-house tire workshop efficiency and identify processes consuming disproportionate resources.

But one point needs highlighting: having indicators is not enough, even if they are the right ones. The real value lies in deviation analysis. For example, when a KPI falls outside the expected pattern, do you know what changed?

A sudden increase in the premature loss rate may point to a batch of defective tires, a new route with an aggressive road surface or a mechanical issue in a group of vehicles. The ability to identify and act on these deviations quickly is what truly defines intelligent tire management.

Governance and auditing processes

As the operation grows, so does the risk of operational irregularities and, occasionally, integrity issues. Tires are high-value assets with high turnover, making them susceptible to losses through lack of control.

Governance in heavy-duty fleet tire management means having regular audit processes. These range from physical inventory counts compared with the system and checking discrepancies between recorded relocations and fitted tires, to disposal control with an assessment report and documented disposition.

It also means having defined decision-making authority. Who authorizes buying new tires? Who approves casing disposal? Who validates sending tires for reconditioning? When these decisions have no owner or criterion, there is room for inefficiency or, in more serious cases, asset misappropriation.

A well-structured audit validates that processes are being followed, system data reflect reality and resources are being used as planned.

In large fleets, quarterly inventory audits and process sampling (inspection, fitting, disposal) are recommended practices. The tire management system should facilitate these checks, providing relocation reports, discrepancy alerts and a complete history per asset.

Tire management in fleets with 50+ vehicles is not a larger version of tire management in small fleets. It is a different discipline, with its own requirements for structure, processes, technology and governance.

The good news is that returns follow investment. Operations that structure tire management with a dedicated system, a trained team and standardized processes can reduce tire costs, extend asset useful life, increase fleet availability and make purchasing decisions that truly optimize the budget.

Every tire that completes its full cycle, every retread used, every decision based on actual CPK… All this comes from management that treats tires as strategic assets.
