What's the factory bolt pattern on the Triumph TR8?

The TR8 uses a 4x4.5" (4x114.3mm) bolt pattern from the factory. VTO Wheels offers this exact bolt pattern in our catalog, so you'll have full compatibility with all our wheel sizes and styles.

What VTO Wheels sizes fit the TR8?

For stock replacement, our 14x6 wheels match the factory spec perfectly. Popular upgrades include 15x6, 15x7, 16x7, and 16x8 for those wanting a more modern look. All sizes use the 4x114.3mm bolt pattern that matches your TR8.

Do I need hub-centric rings for VTO Wheels on my TR8?

Most likely yes – the TR8's hub bore is typically around 60-65mm, while our wheels have a larger center bore for universal fitment. We recommend measuring your hub diameter and ordering appropriate hub-centric rings to ensure proper centering and vibration-free operation.

What offset should I run on my TR8?

Factory offset was around +25mm to +30mm, which works well for a stock appearance. Our offset range of -7mm to +38mm gives you options from aggressive flush fitment (lower offsets) to conservative stock replacement (higher offsets). Most TR8 owners stick between +15mm to +30mm for the best balance of appearance and clearance.

Triumph TR8

The TR8 came factory-equipped with 14x6 steel wheels wearing a 4x4.5" (4x114.3mm) bolt pattern – pretty standard stuff for British sports cars of the era. Triumph used simple styled steel wheels with hubcaps on most models, though some higher trim variants got basic aluminum wheels. The factory offset was typically around +25mm to +30mm, giving the TR8 its characteristic stance without any fender interference issues.

For VTO Wheels compatibility, you're looking at our 4x114.3mm bolt pattern options, which gives you plenty of choices from our catalog. Popular sizes include 14x6 for that stock look, or step up to 15x6, 15x7, or even 16x7 for a more aggressive stance. Our offset range of -7mm to +38mm covers everything from flush-fitment builds to conservative stock replacements, and all our vintage-style aluminum wheels will shed serious weight compared to those heavy factory steelies.

The TR8 represents Triumph's ambitious attempt to keep the TR series alive in the late '70s by dropping in Rover's 3.5L V8 – essentially creating a budget Corvette competitor. Only produced from 1978-1981 with just over 2,400 units built, it's become increasingly collectible among British sports car enthusiasts who appreciate its unique blend of classic TR styling with legitimate V8 power.
