Triumph TR5 Tyres
Triumph TR5 1967-1968
Triumph TR5 Tyres Explained
- Longstone's recommended Triumph TR5 classic tyre is the 165 HR 15 PIRELLI CINTURATO CA67 or 165-15 Michelin XAS.
- The 165 HR 15 PIRELLI CINTURATO CA67 is a recommended TR5 tyre as it is a proper period tyre that will offer extremely progressive handling.
- We recommend the 165-15 Michelin XAS for Triumph TR5s it is a period-correct sports car tyre; an asymmetric classic tyre that offers outstanding levels of grip and directional stability.
- The PIRELLI CINTURATO ™ CA67 and Michelin XAS are ideal classic tyres for the TR5.
- It is interesting to bear in mind that when this TR5 was available Triumph had the option of fitting low-profile TR5 tyres, but they didn't. The TR6 also came out with 165-15 Michelin XAS. This is because fitting modern low-profile tyres would spoil the handling of a TR5 and TR6.
- However if you do really want to fit a wider tyre then fitting the 185/70 WR 15 PIRELLI CINTURATO CN36 or 185/70 VR 15 Michelin XWX will give you a wider tyre without having such a derogatory effect on the cars handling because they are period tyres developed to suit a car like a TR5.
Triumph TR250 Tyres
- The US version of the TR5 was dubbed the 'TR250', fitting 185 R15 tyres as standard.
- The best 185 R15 TR 250 tyre is the 185 VR 15 PIRELLI CINTURATO CA67.
- The UK's 165 R15 spec tyres offered nimble, sporty handling, whereas the 185 R15 US specification TR250 tyres offered more comfort and lower revs while at a cruising speed.
- The 180 HR 15 Michelin XAS is a great alternative option for a taller tyre on a TR250, offering a balance between the 165's nimble handling and the 185's wider more substantial footprint.
Triumph TR5/TR250 Innertubes
- Because Triumph fitted wire wheels, it should fit innertubes. We suggest the Michelin 15E as the best innertube for a TR5 and TR250 on 165 R15, 180 R15, and 185/70 R15 tyres.
- The ideal tube for 185 R15 tyres is the Michelin 15F.
Triumph TR5 History
The classic Triumph TR5 was built for a 13 month period between August 1967 and September 1968 by the Triumph in Coventry, England. Visually identical to the classic Michelotti styled Triumph TR4, the TR5 hid the main differences under the body, the most significant of which was the engine. The TR5 boasted a 2.5-litre straight-6 fuel-injected engine developing around 150 bhp. This engine was carried forward to the classic Triumph TR6.
At the time, fuel injection (or PI petrol injection, as it was sometimes then called) was uncommon in road cars. Triumph claimed in their sales brochure that it was the "First British production sports car with petrol injection". This engine could propel the TR5 from 0 to 50 mph in just 6.5 seconds, and on to a top speed of 125 mph. Road tests at the time reported slightly different performance figures surprisingly.
TR5 Tyres Q&A
A: Triumph fitted 165-15 SP41 tyres to the TR5. The best tyres currently for a TR5 are 165HR15 PIRELLI CINTURATO CA67 or Michelin XAS. Many people want a wider tyre, fitting a period 185/70-15 Pirelli CN36 will not have a bad effect on the handling but the modern tyre will make the car track and be less progressive.
A: Yes. Because the TR5 has wire wheels it should fit inner tubes
