I was at the track last sunday and got to talking tire pressure with some guys and it made me curious what other folks put in their tires, and for what conditions.
What do you guys use for:
Motocross - Natural terrain, some jumps but not big air - Front/Back
Supercross - Man-made track, big jumps & whoop-sections - Front/Back
Offroad/Scrambles - woods/creeks/sand - Front/Back

Way more ap to flat in mud because of extra weight and hidden edges.
SX/AX - 12f 10r
Offroad(rocky) - 15f 14r

Experience the best suspension feel, traction and flat protection you've ever had...you can thank me later.
8psi is too low, the tire rolls on itself too much.
11/10 if there is no rock
Off-road 15/15
I always run a 19" wheel so I run a lot offroad
12 on the rear
The pressures go up so I normally check after each moto.
Thanks for the replies!
I ran 13 front 12 rear at Rio. Didn't matter once the shock blew.
BTW, I found the detonation issue on the 465. The main jet splash guard from 1982 fell off and was blocking fuel flow to the main jet. She was just a bit lean on the top.

whereas in a car on high traction surfaces, lower pressures take advantage of that flex in the sidewall can carcass to reduce wheelspin and create more traction.....
Einsteinshit.
I'm not counting running over a nail here,but flats from fatigue or pinch.
And moto,not 3 hr rides,that could be different ,but I've practiced 3 hrs many many times.
Best thing I ever did was a buy an accurate tire pressure gauge.
Ended up throwing away 3 gauges because they were 3.5 psi heavy! We had 4 gauges at the track one day, all dial, 2 read 13, 2 read 16.5. I paid up for a nice liquid filled gauge with half percent accuracy that I will use for the rest of my life.
Motion Pro has one of the best gauges in the industry, look around at the next MX/SX race and see what the teams are using. I've had one for a few years and it's worth it's weight in gold IMHO.
as for pressures, lower pressure gives you a bigger footprint so more traction but it's a tradeoff vs. pinch flats. find your happy place.
In mud and sand I'd run a bit higher pressure to get the tire to dig thru the stuff on top and get down a bit more and keep a rounder carcass to shed more mud.
So on almost all the tracks we ride they are sandier than they are loamy. Very soft and fluffy. For me in this stuff I run low pressures like 9-11. If I trry 13 its no good for me.
