Hi The Cinturato CN36 is a 1970's low profile tyre developed in conjunction with cars of this period. It is developed to be fitted to cars that originally had a thinner full profile tyre. so the handling will be better on a TR than more modern tyres of this size. there are no sipes in the CN36. The more open tread of the CN36 should make it better than the A048R in the wet. But i would agree that the A048R will give more grip in the dry on a perfectly smooth race track. However the CN36 will give better handling on the road on a TR (unless the steering and geometry have been changed to suit more modern tyres)

Very exciting. Pirelli have just reproduced their CN36 Cinturato in the size 185/70R15, as fitted to lots of TR's. what do you think

Whoopee!! Stop The Press!!! Pirelli have just reproduced their famous Pirelli Cinturato in the size 165HR15 CA67. http://www.longstonetyres.co.uk/page/165hr15-pirelli-cinturato-ca67.html what could be better on a TR4, TR5 or TR6. (personally i prefer a TR2 or TR3 on a 155HR15, but i know lots of people like a bigger tyre) I know there is a variety of opinions about weather fatter tyres are better; and Pirelli will reproduce a 185/70VR15 CN36 hopefully soon. I shall post when they do. This is sort of an honest commercial post which you might want to take down.

Wow. generally speaking from the Triumph fraternity people seem to want to over tyre their cars with modern rubber. I think TR2 & TR3 155HR15 Pirelli Cinturato (or XAS) and for TR4, TR5 & TR6 165HR15 preferably Michelin XAS. More modern tyres have squarer shoulders which increase the violent brake away that you were talking about when discussing the difference between cross ply and radial. radials do brake away more violently, but the more modern the radial and the wider the tyre the more difficult it is to catch. Fat tyres are for cars that don't loose traction. more modern cars that suit wide tyres have very different geometry and are mostly front wheel drive (yuk). Thet are not designed to be progressive. so as well as fitting the right size tyre, a period tyre that is designed to compliment cars of this period will also enhance the handling. But of course the other big attraction to wide modern tyres is they are cheap. by the way, that is me in the video, sorry about the berry here's another one. a TR2 on crossply racing tyres. just a shame about the driver. https://www.youtube.com/watch?v=wWPRxT9jw1w

Cheers Andy, may i say what a great recomendation, However was that what the TR5 fitted as Standard. i'm pretty sure the TR6 fitted XAS but i am unsure about the TR5 because i have found an insurance book that says SP41 165-15 which is a period Dunlop radil tyre. now i would fit XAS. the SP41 is no longer made. and the XAS is better.

Hi Does anyone know what was the original tyre on a TR5? I think it was 165-15 Dunlop SP41. any thoughts? Dougal
