I have a stock 2002 400EX and i weigh 235. what do you think i should run for pressure in tires??? do i put same in front as back??? the dealers said put 5 psi, but i have heard of guys putting as much as 10 psi??? let me know what you all run....i still have stock tires if that means anything. THANKS

 

well pick up your owners book and see what it recomends. also, it depends on what your riding on, mud, sand, etc, etc...

 

Woods racing and motocross here.......3 to 5psi max.

Be careful with experimenting with high air pressures. If you put enough to "round" the profile of the tire and leave it there for more than a day or two, the tire will never go back into it's original "flat" profile. This applies to all Ohtsu tires that come as stock equipment on the Honda's.

 

Depends on ridding conditions. I dont think there is a real science to it I pump mine up with a bicycle pump until they are both at a good feeling presure. I weigh 230lbs if I put a gauge on them probibly 5psi

 

I stock Honda tires, we run 4.5 on the fronts and 4 on the back. The difference in your weight and the average rider isn't more than 70 lbs so you wouldn't need to adjust air pressure by more than 1 lb.

I like a little more in the front to stop tire roll.
