Tires are the single largest variable cost in most commercial fleet operating budgets — accounting for 3–5% of total fleet operating cost — yet most fleets manage them reactively. A tire replaced at 4/32" tread depth that could have been retreaded at 2/32" is $180 in avoidable cost per tire. A tire running 8 PSI low is wearing its outer shoulders 25% faster and delivering 3% worse fuel economy on every mile it travels. A set of tires rotated on schedule delivers 15–20% more mileage than the same tire set run to failure in the original position. The math is straightforward but the execution requires a system: tread depth tracked per tire per position at every service, pressure monitored against load and application, rotation executed on schedule, and retreading decisions made with data on original tread depth and casing condition rather than visual guesswork. Oxmaint's fleet tire management module provides that system — from tire purchase and mounting through rotation scheduling, pressure monitoring, tread tracking, retreading decisions, and disposal cost recovery.

Tire Position Tread Depth Matrix — Track Every Tire Every Service
Tread depth varies by axle position, load, and driving conditions. Tracking it per position at every service is the foundation of an effective tire lifecycle programme. Oxmaint records tread depth per position with each service event — showing wear patterns that indicate alignment, inflation, and overload problems before they destroy the casing.

Five Components of a Structured Fleet Tire Program
A complete fleet tire programme is not just purchasing and replacement — it is a lifecycle system. Oxmaint manages all five components, connecting purchasing data to lifecycle tracking, pressure monitoring, rotation compliance, and retreading decisions.
01
Tire Purchasing & Inventory
Spec management by vehicle class, vendor cost tracking, inventory levels by SKU, and purchase order generation from Oxmaint when stock falls below minimum par levels.
02
Rotation Schedules
Rotation work orders generated automatically by mileage — steer, drive, and trailer positions rotated to equalise wear. Rotation history per position tracked against tread depth readings.
03
Pressure Monitoring
Target pressure per tire position per vehicle class configured in Oxmaint. TPMS sensor data integration available. Pressure check work orders generated at each service interval.
04
Tread Depth Tracking
Tread depth recorded per position at every service. Wear rate calculated per tire per position. Abnormal wear patterns flagged — triggering investigation of alignment, inflation, or loading issues.
05
Retreading Program
Retread eligibility assessed from original mount tread depth and casing condition records. Retread candidates flagged at removal. Cost per mile compared — new vs retreaded — per tire class and application.
TPMS sensor data from Doran, Pressure Pro, and OEM systems feeds Oxmaint — low pressure events generate inspection work orders automatically before tires run damaged.
AI Wear Analysis
Pattern detect
Root cause from wear data
AI analyses tread depth variance patterns across positions — identifying shoulder wear (inflation), cupping (shocks), and feathering (alignment) before casings are damaged beyond retreading eligibility.
Telematics Mileage Trigger
Auto-trigger
Rotation PMs by actual miles
Telematics odometer data triggers rotation work orders at configured mileage intervals per vehicle class — no manual interval tracking, no missed rotations from incorrect odometer entries.
Cost Per Mile Analytics
Fleet-wide
CPM by tire brand and spec
Oxmaint calculates cost per mile by tire brand, spec, vehicle class, and application — quantifying the true lifecycle cost difference between tire specifications and retreading programmes.

Saved per tire identified for retreading vs premature new replacement
"We were spending $380,000 a year on tires for 95 trucks. Oxmaint's tread tracking showed we were scrapping casings that should have gone to retread — we were replacing at 4/32 on a programme that allows retread at 2/32. We saved $54,000 in year one just from the retreading programme. The rotation compliance cut our steer axle tire cost per mile by 18%."

Frequently Asked Questions
Q1How does Oxmaint schedule tire rotation work orders automatically?▾
Rotation work orders are generated by actual mileage from telematics sync or odometer entry — per vehicle class with configurable rotation intervals. Steer, drive, and trailer positions each have independent rotation schedules based on wear rate data from your fleet's history.
Q2Can Oxmaint integrate with TPMS systems for real-time pressure monitoring?▾
Yes — Oxmaint integrates with Doran, Pressure Pro, Bendix SmarTire, and OEM TPMS systems. Pressure threshold alerts auto-generate work orders with the tire position, vehicle ID, and current pressure reading pre-populated.
Q3How does Oxmaint identify tires eligible for retreading?▾
Oxmaint tracks each tire's tread depth history and mounting records. When a tire is removed, the system evaluates casing age, total mileage, original tread depth at mount, and current depth — flagging casings that meet retreader eligibility criteria before they go to disposal.
Q4Can Oxmaint track cost per mile by tire brand and spec for purchasing decisions?▾
Yes — Oxmaint calculates cost per mile per tire SKU from purchase cost, total mileage delivered, and retread value recovered. Side-by-side comparison by brand, spec, and vehicle application gives fleet managers data-driven purchasing decisions.
Q5Does Oxmaint track tire inventory and generate purchase orders when stock is low?▾
Oxmaint manages tire inventory by SKU with configurable minimum stock levels. When inventory falls below par, Oxmaint generates a purchase order — preventing emergency tire purchases at premium pricing when a vehicle is grounded waiting for stock.
