1978 Triumph TR7 Wheel Fitment Guide — What Works & What to Avoid
The 1978 Triumph TR7 uses a 4x95.25 bolt pattern with a 57.1mm hub-centric center bore. Your stock wheel measures 13x5.5 with a 25 offset. You can step up to 13x6, 13x6.5, or 13x7 while staying with the original diameter, or upgrade to 14-inch sizes in 5.5, 6, or 6.5 widths. Fifteen-inch wheels fit too, available in 6, 6.5, and 7-inch widths. Since fitment is square rather than staggered, you'll run the same size all four corners.
Make certain any wheel you choose has the 4x95.25 bolt pattern—no other pattern will fit this TR7. If a wheel's center bore exceeds 57.1mm, install hub-centric rings to ensure proper centering and a secure fit. Wider or more aggressive offsets can encroach on fenders and suspension geometry, so verify clearance before committing to the largest or most offset-forward options available.
Every wheel we offer for your TR7 is verified to bolt on and ships free to the lower 48 states. Browse our full selection to find the style and size that suits your classic sports car best.
