Triumph TR Tires
The British made Triumph offered such great, fun, budget, sports cars from the golden age of motoring. Something for everyone to enjoy. What makes these classic cars so much fun is their light predictable handling. A critical part of maintaining this lightness is not over tire sizing these great fun little TR’s and also fitting a genuine period sports car tire that is developed in conjunction with cars of this period.
The Triumph TR2 and TR3 were originally fitted with crossply 5.50 - 15 tires. We, however, advocate for a transition to radial tires. Our top pick for these models is the 155 HR 15 PIRELLI CINTURATO CA67. For the TR4, TR5, and TR6, the original size was 165R15, and the go-to selection is the 165HR15 PIRELLI CINTURATO ™ CA67. The TR2 and TR3 can also fit the 165HR15 PIRELLI CINTURATO ™ CA67 without any issues.
Triumph TR Classic Tires
While low-profile tires like the 185/70R15 became available in 1968, Triumph opted to remain consistent with the 165R15 tires for the TR6. The reason? Triumph recognized that these nimble sports cars displayed less favourable handling characteristics with wider tires. Installing contemporary tires, such as the 195/65R15, might lead to issues like abrupt skidding, aquaplaning, and reacting unpredictably on inconsistent road surfaces. Hence, our advice leans towards retaining the original radial tires.
For those drawn to the aesthetics of a broader tire filling the wheel arch, the 185/70VR15 PIRELLI CINTURATO ™ CN36, a genuine period tire, is a worthy consideration. These tires, designed specifically for cars of that era, ensure continued smooth handling due to their rounded shoulders.
Come 1975, the TR7 featured either the 175/70R13 Goodyear G800S or Michelin XV. In today's context, the 175/70VR13 PIRELLI CINTURATO™ CN36 emerges as the best classic tire in the size. As for the 5-speed TR7 released in 1979, fitted with 185/70R13 tires, we stand by the 185/70VR13 PIRELLI CINTURATO ™ CN36 as the ideal choice.
