Front tire pressure???

It should say on the tires, maybe not because they are stock. I will have to take a look at my manual? Where is your manual good sir? :D
 
tire pressure will be determined by your riding style and track conditions
but no more than 10 front or back
 
For MX with Kenda Claws on front 5-8 psi depending on surface, Kenda Max rears 5psi, any surface, works for me.

Manual says for fronts, recommended 4.3 ... minimum, 3.8, ... maximum 4.7psi.

Rears, recommended 3.6.... minimum, 3.1.... maximum, 4.0 psi, but that is with the 21 x 10x 8.

I have never used any more than 5psi in the rears with 18 x 10.5 x 8, tyres for Mx.
