2006 Acura TL Stock Tire Size: The Definitive Specification Guide
The 2006 Acura TL represented a refined evolution of Honda's luxury sedan lineage, combining a 3.2L VTEC engine, SH-AWD technology (on select trims), and a ride quality that rivaled its German counterparts. At the heart of every one of these vehicles is a single, often overlooked specification: the stock tire size. Get it wrong, and you risk compromised handling, inaccurate speedometer readings, premature wear, and voided warranty coverage on related components. Get it right, and the TL delivers exactly the balanced, composed driving experience Acura engineered.
This article provides an authoritative, data-driven breakdown of every factory tire specification for the 2006 Acura TL across all trim levels. Whether you're replacing worn tires, planning a seasonal rotation, or verifying OEM compliance before a purchase, this is the resource you need.
Key Takeaways
- Primary stock tire size:
225/50R17— standard on all 2006 Acura TL trims including the SH-AWD model. - Spare tire: Compact temporary spare (
T135/80D16) or full-size spare depending on trim and package. - Tire pressure: 32 PSI cold for all configurations per Acura's official placard; maximum sidewall pressure (e.g., 44 PSI) is not the recommended operating pressure.
- Recommended replacement: Michelin Pilot Sport MXM4, Bridgestone Potenza RE980AS, or Yokohama adanza V552 for matched OE performance.
- Wheel bolt pattern: 5×114.3 mm; center bore 64.1 mm; lug nut torque spec 76 ft-lb (103 N·m).
Factory Tire Specifications by Trim Level
Acura equipped the 2006 TL with a consistent tire dimension across all three trim designations — Base, Technology Package, and SH-AWD — which simplifies sourcing but requires careful attention to load index and construction type when selecting replacements.

Trim-Level Variation Analysis
| Trim | Engine | Drivetrain | Stock Tire | Optional Wheel Upgrade | Notable Differences |
|---|---|---|---|---|---|
| Base | 3.2L V6 | FWD | 225/50R17 91V | None from factory | Identical tire spec to other trims |
| Technology Package | 3.2L V6 | FWD | 225/50R17 91V | 18-inch forged alloy (optional) | Requires 225/45R18 when upgraded; GPS/nav added |
| SH-AWD | 3.2L V6 | Super Handling AWD | 225/50R17 91V | 18-inch forged alloy (optional) | All-wheel drive adds ~150 lbs front-rear weight bias impact |
Spare Tire and Temporary Mobility Options
The 2006 Acura TL ships from the factory with a compact temporary-use spare tire located in the rear trunk well. This is critical to understand because many owners mistakenly attempt to mount a full-size matching spare, which complicates storage and weight distribution.
| Spare Type | Size / Specification | Maximum Speed | Maximum Distance |
|---|---|---|---|
| Compact temporary spare | T135/80D16 | 50 mph (80 km/h) | ~50 miles (80 km) |
| Full-size spare (some SH-AWD packages) | 225/50R17 (matching) | Per tire rating (V = 149 mph) | No restriction beyond tire life |
Spare Tire Pressure Recommendation
The compact spare requires significantly higher inflation than the primary tires — typically 60 PSI cold. Always verify the pressure label mounted on the spare tire sidewall before inflating. Under-inflated spares are a leading cause of bead-separation failures during emergency deployment.
