    Hi everyone,

    I ride a 2016' S3R fitted with the OEM Supercorsas V2.
    According to the Speed triple manual, the recommended tyre pressures are 2.3 on the front and 2.9 on the rear, for road use. This is what I use and so far so good for what I do.

    Now, after looking at Pirelli's website, the recommended pressures are somewhat lower for the front (2.0-2.2) , but way lower for the rear (1.6-1.8) !!
    https://www.pirelli.com/tyres/en-gb.../sheet/diablo-supercorsa-sp#/technical-advice

    It looks to me that the pressures recommended by triumph are more relevant for a road use where tyres will hardly warm up, and to prevent a ridiculously quick wear of these £££ supercorsas.

    Is anyone able to explain why there is so much difference for the rear pressure?

    thanks!

    Rémi

    The data sheet you have referenced looks to be for Track use, where the application is more severe, as I don't know many people who use tyre warmers on their road bikes

    Track pressures are too extreme for road use, but many Speed3 riders tend to drop pressures a tad. I'm running Metzeler M7RR at 32psi front / 36 rear.
    Personally wasn't a fan of Supercorsa's when cold or wet (plus wear pretty quick).

    Be aware lower pressures require a little longer warm up.

    How do you figure that? Running them a bit softer results in a bit more flex of the carcass making them warm up faster. As an example have you ever felt an under inflated tyre on your car, it will be much warmer than any others that are at the “correct” higher pressure.

    On a cold wet day like today, the pressures ares irrelevant as SuperCorsas will never warm up, The traction control system will be working overtime though ;)

    That's quite true, I experienced a 3 seconds long intervention of the traction control while rolling on the throttle too enthusiastically the other day. I was on the motorway under the rain. I was truly amazed how smoothly the electronics kicked in, you can barely feel any wobble when it switches on and off. It was much more blunt with my previous bike (bmw)

    Warm up from rest to working pressure, not work at a higher temp
