12.5 and I check it again in the middle of the day if the weather fluctuates enough.

I fill to 11 PSI and after one lap, they are at 12.
I WILL go up to as high as 14, if conditions call for it, to prevent pinch flats. I used to do this for second motos at Cahuilla, if it was a big race, as square-edged bumps would form on high-speed straights.

Depends on the tyre. But regardless I set mine right when I get to the track, then do a couple warm up laps, and set it again. It usually jumps up a 0.07 bar or so due to the temperature rise from the warm up, especially the rear. I've been running 0.90 bar in my Michelin tyres, a bit lower for Dunlops or Bridgestones.

Depends on the track and which tires 8)

For Cahuilla with Dunlop 3S or 33's, we run 12.5 PSI rear and 13.5/14 PSI up front. Similar pressures with Pirelli's. Mammoth or GH rough and the pressures have to increase a bit.

Tire pressure is tire specific. For example,There is a recommended pressure for Dunlopís. I run what is recommended and have nearly zero issues with wear and tear, plus I have been shocked to discover the performance gain in doing so.

I was surprised at the difference when I went up to 13.5 in the front. I was running 12 front and back myself, until I talked to someone that was running 13 rear, 13.5 front. It was a change that I really noticed, and liked.
Mammoth Iíve ran 15 in my kids bikes over the years and always got at least one flat in a main. Iím sure Iíll get one this weekend. Lol

This is 'merica, get that bar shit out of here.   


In my Michelin Starcross tires, I run 12.3846 in the rear, and 12.9482 in the front.

What air temp are you running?

After running go karts for years, we have found a lot tire pressure gauges give out wrong pressures numbers.  Guys think they are running 13 pounds, but after checking it with different tire gauges, they were running at 16 pounds.  Check you gauges with other riders gauges at the track.

I only use nitrogen.
