Optimal tire pressure

[Robin Mayer]

Whats te optimal tire pressure? When they are warm.

[Tr!st@n]

In my opinion its around 1.00 bar warm, but im not a pro.

too high

[Birel-Rotax 42]

Personally I run .6 bar. I usually just run stock setup with the exception of caster, and the bars.

My soft tyres usually show between 0.88 and 0.95 bar at the end of a run.

[Cory_Hayes]

how much do you slide around?

how much do you slide around?

I never really analysed it by watching my replays but I try to slide as less as possible. Do you think my temperatures show too much slide?

[Cory_Hayes]

Maybe....
I normally have my tyres sit at around
.8 bar... and I try to even them all out ( hot pressure )

[dibu]

I also even them out.
0.80 bar gives me the feeling of having less grip than at 0.90 - at more than 0.95 the tyres start to overheat and at 1.00 you are riding a dead horse.

Next time I'll watch my replay and look how much I'm really sliding.

Here an old KRP discussion about tyres, maybe it's still interesting:

Here some general setup tips from real life (not directly tyre pressure):

Sorry this (good) setup guide I only found in German language - maybe google or another translator helps:

...its not really about the pressure it hads...its more about the temp of the tyre....( the way I see it, and it works really well for me)

This means you're ignoring the pressure and use the optimal tyre temperature as reference?
Which temperature should a warm tyre reach e.g. KZ1?

You are one of the fastest guys here, so I think it's not wrong to follow your proposals to find a good setup.

Optimal tyre temp.....I let my tyres between 50-70 degrees,  I will normally offset tyre pressures, to make certain tyres stay colder or get warmer. If you know what I am saying

Thanks for your hints. I always looked for equal pressure at my warm tyres. But your approach sounds logic, I'll give it a try.
