Understanding 1975 Triumph TR7 Wheel Fitment
Getting the right wheel fitment on your 1975 Triumph TR7 comes down to four critical measurements:
Bolt Pattern: 4x95.25
The bolt pattern (also called PCD) is the most fundamental fitment spec — it determines which wheels will physically bolt onto your vehicle. The 1975 Triumph TR7 uses a 4x95.25 pattern, which is shared with many other Triumph models. This means you have a massive selection of aftermarket wheels to choose from.
Center Bore: 57.1mm
The center bore is the hole in the middle of the wheel that sits over your hub. The 1975 Triumph TR7 has a 57.1mm center bore. If your aftermarket wheels have a larger bore (which is common), you'll need hub-centric rings to eliminate vibration at highway speeds. We include the correct hub rings with every wheel and tire package.
Offset & Width
Offset determines how far the wheel sits inward or outward relative to the hub face. A lower offset pushes the wheel outward for a more aggressive, flush look. A higher offset tucks the wheel further under the fender for a conservative fitment. The factory offset of +25 is a good baseline — going 5-15mm lower will give you a more flush look.
