Triumph TR6 Tyres

Choosing the correct Triumph TR6 tyres starts with confirming which market your car was built for. The TR6 uses a 15-inch tyre fitment across a production run spanning 1969 to 1976, though the standard size varied between home market and export specifications. TR6s built for the UK and Europe were fitted with 165HR15 on 5.5J x 15-inch wheels as standard. US-specification cars used 185R15, so any TR6 imported from North America may not match the home-market tyre specification.

165HR15 is the correct period reference size for UK TR6 tyres. Many owners run 185/70R15, which provides an overall diameter very close to the original 165HR15. Many TR specialists advise against going wider than 185/70R15, as wider modern square-shouldered tyres can reduce the progressive handling characteristics the TR6 is known for.

According to the Michelin period guide, TR6 tyre pressures for a 165HR15 XAS fitment are 22 psi front and 26 psi rear. Triumph TR6 tyre pressures for modern radials typically run higher in practice, with most owners settling on 26 to 28 psi front and 28 to 30 psi rear, finding the handbook figures leave the steering heavy and the tyres looking underinflated. We stock the complete range of TR6 tyre pressure guidance, wheel options and suspension components for all models. Our Triumph TR6 wheels section covers steel wheels, wire wheels, Classic 8-spoke alloys and Revolution alloys across all TR6 variants.
