Tire Position Guide
Last Updated: March 2026
Commercial trucks use different types of tires for each axle position — steer, drive, and trailer. Using the right tire in each position is critical for safety, performance, and tire longevity. This guide explains the differences and helps you choose the right tires for your rig.
1. Why Position Matters
Each axle on a commercial truck serves a different purpose, and the tires on each axle face different stresses:
- Steer axle: Handles steering forces, cornering, and front-end load — needs precise handling and lateral grip
- Drive axle: Transmits engine power to the road — needs maximum traction and durability under torque
- Trailer axle: Carries load with minimal steering input — needs even wear and low rolling resistance
Using the wrong tire in the wrong position can result in: premature tire wear, reduced fuel efficiency, poor handling, increased blowout risk, and voided tire warranty.
2. Mixing Tires — Dos and Don’ts
- NEVER mix radial and bias-ply tires on the same vehicle
- NEVER mix tires of different sizes on the same axle
- AVOID mixing brands or tread patterns on the same axle — it can cause uneven wear and handling issues
- OK to use different brands/patterns on different axles (e.g., Landspider steer + Koryo drive)
- OK to rotate used steer tires to trailer position at 50% tread life to maximize tire investment
For dual configurations (drive axle): Both tires on the same side must be the same size, brand, tread pattern, and within 4/32" of the same tread depth. Mismatched duals cause the smaller tire to drag and the larger tire to overwork.
3. Fleet Buying Strategy
For fleet managers purchasing tires for multiple trucks, we recommend:
- Standardize on one steer tire and one drive tire across your fleet — simplifies inventory and rotation
- Buy in bulk — our volume pricing starts at 8+ tires with additional discounts at 32+
- Rotate worn steers to trailer position — gets an additional 30–50% life from each steer tire
- Schedule regular inspections — catching alignment issues early prevents premature tire wear
Our fleet team can build a custom tire program for your fleet. Learn more about our Fleet Program.

Tire Positions Explained
Steer Tires (AP — All Position)
Designed for: Steering axle (front)
Key characteristics:
- Tread pattern: Ribbed (longitudinal grooves) for precise steering response and straight-line stability
- Compound: Harder rubber for long tread life and resistance to irregular wear
- Shoulder: Reinforced shoulders to resist curbing damage and scuffing
- Priority: Handling, lateral stability, fuel efficiency, even wear
Can they be used elsewhere? Yes — "AP" (All Position) steer tires can technically be used on any axle. However, they lack the deep traction lugs needed for drive axles. Many fleets rotate worn steer tires to trailer positions to maximize tire life.

Drive Tires
Designed for: Drive axle(s) — tandem or single
Key characteristics:
- Tread pattern: Aggressive lug/block pattern for maximum traction during acceleration and braking
- Compound: Softer, high-grip rubber that flexes under torque without chunking
- Siping: Fine cuts in the tread blocks for wet/winter grip
- Depth: Deeper tread (24–32/32") for longer life under high-stress conditions
- Priority: Traction, durability under torque, resistance to stone drilling and chunking

Trailer Tires
Designed for: Non-powered trailer axles
Key characteristics:
- Tread pattern: Ribbed or multi-rib pattern — similar to steer tires but optimized for free-rolling application
- Compound: Low rolling resistance rubber for maximum fuel efficiency
- Sidewall: Reinforced to handle high loads and lateral stress during turns
- Priority: Even wear, low rolling resistance (fuel savings), high load capacity, durability
Important: Never use trailer tires on a drive or steer axle — they are not designed for powered or steering applications and may fail under those stresses.

Position FAQ
Technically yes, but it's not recommended. AP tires have a ribbed tread pattern optimized for steering, not traction. On a drive axle, they will provide less grip — especially in rain, snow, or loose gravel. You'll also experience faster tread wear. For best results, use a dedicated drive tire with a lug/block pattern on your drive axle.
Unlike passenger cars, commercial trucks don't typically "rotate" tires between positions because steer, drive, and trailer tires are different types. However, you should: (1) Inspect tires weekly, (2) Check and adjust pressure weekly, (3) Rotate duals side-to-side every 30,000–50,000 miles if you notice uneven wear, (4) Move worn steer tires to trailer position when they reach 6/32" to 8/32" tread depth.
Per FMCSA regulations: Steer tires must have at least 4/32" tread depth, and drive/trailer tires must have at least 2/32". However, for safety, we recommend replacing steer tires at 6/32" and drive tires at 4/32". Tires below legal minimums will result in an out-of-service violation during DOT inspections.
Uneven steer tire wear is almost always caused by alignment issues, not the tire itself. Common causes: (1) Toe-in/toe-out misalignment (feathered wear pattern), (2) Camber misalignment (one-sided wear), (3) Worn king pins or tie rod ends (cupped wear), (4) Improper inflation. Get your front end inspected and aligned before installing new steer tires — otherwise the new tires will wear the same way.
