Re: Time difference various tyre compounds

@Monzstar83Still have to be careful with surface temps in the corners. Just makes overall tyre temp manageable especially on high temp circuits.

I’m wondering if your pressures are too high perhaps. I could in theory run max pressures to get maximum rare length out of them. But I don’t as I still look to keep surface temps las low as possible. Think if you exceed 115 degrees you lose traction. I bow to @Meza994 on this though

    This is the thing though - I set them as high as I can without overheating, my tyres rarely go over 90, so perhaps under-pressured? Bahrain though I’m running all 1 notch from the max pressure available IIRC. Perhaps I can do a race with them as they are and another with them on max, track on telemetry app. Perhaps this can give me a better indication.

    @Monzstar83 I’m not really the best to ask on this as I’ve been running surface only for so long now I can’t remember what it’s like to use carcass temps anymore. If I did after a couple of laps my fronts especially would be constantly yellow. 🙄

    @Monzstar83So even though it shows green it can already be losing considerable grip, the tyre indications are not the best..

    Just a little help for you:

    Perfect surface grip:85-115° 5° below costs 1.8% grip, 5° above costs 3.75% grip, i think 120° still shows as green though its almost 4% down on grip

    Perfect carcass grip: 85-100° 4° below costs 2% grip, 4° above costs 4% grip so even 103° is only 97% grip anymore but still showing green

    So even though it might show green you could be down by 7% grip which is a big deal but at least to me those high surface temps only happen on the front but going a little too quick on throttle might have same effect on rears

    @Meza994 thank you - some really useful info there 

    It sounds like my carcass temps are probably bang in the window, but maybe I’m having issues with surface. Will track using a telemetry app and see
