Triumph TR3A
The Triumph TR3A came factory-equipped with 15x4.5" steel disc wheels using a 4x4.5" (4x114.3mm) bolt pattern - a significant upgrade from the earlier TR3's wire wheels. These stamped steel wheels featured a simple, functional design with painted finish and were paired with basic steel hubcaps. The narrow 4.5" width was typical for the late 1950s and early 1960s, designed around bias-ply tires and the car's lightweight construction. Triumph stuck with this wheel specification throughout the TR3A's production run from 1958-1962, maintaining consistency across all trim levels.
For TR3A owners looking to upgrade, VTO Wheels offers several compatible options in the matching 4x114.3mm bolt pattern. Our 15x6" and 15x6.5" wheels provide a nice step up from the factory 4.5" width while maintaining the original 15" diameter, perfect for improved tire selection and handling. For those wanting a more aggressive look, our 15x7" and 15x8" options really fill out the wheel wells nicely. All VTO wheels come in vintage-appropriate finishes like polished aluminum or silver with machined lip that complement the TR3A's classic British sports car aesthetic.
The TR3A represents the sweet spot of the early Triumph TR lineup - more refined than the raw TR2 but maintaining the pure driving experience that made these cars legendary. With its 2.0L inline-four and lightweight construction, it became a favorite among weekend racers and sports car enthusiasts who appreciated its honest, no-nonsense approach to performance.

Frequently Asked Questions
| Question | Answer |
|---|---|
| What's the factory bolt pattern on a Triumph TR3A? | The TR3A uses a 4x4.5" bolt pattern, which converts to 4x114.3mm in metric. VTO Wheels carries this exact bolt pattern, so our wheels will bolt right up to your TR3A's hubs without any adapters needed. |
| What VTO Wheels sizes will fit my TR3A? | For stock replacement, our 15x6" wheels are perfect upgrades from the factory 15x4.5" setup. Popular performance upgrades include 15x6.5", 15x7", and 15x8" widths. Some owners also go with 14x6" for a more vintage look or 16x7" for modern tire selection. |
| Do I need hub-centric rings for VTO Wheels on my TR3A? | Most likely yes. The TR3A has a specific center bore size, and VTO Wheels are manufactured with a larger universal bore to fit multiple applications. We'll include the correct hub-centric rings with your wheel order to ensure proper centering and vibration-free operation. |
| What offset should I run on my TR3A? | For the TR3A's narrow fenders and lightweight suspension, we typically recommend staying in the +10mm to +25mm range from VTO's available -7mm to +38mm selection. This provides good fitment without extensive fender modifications while maintaining proper suspension geometry. |
