OK I am trying to figure out tire pressures. If I lower the pressure what will happen and when I raise it? I have stock tires on both bikes. I am thinking that when I raise the pressure I will get less pressure and let me slide around and fish tail better and what not? Thanks [img]i/expressions/face-icon-small-smile.gif[/img]

 

basicly the lower the pressure the more traction you will get

you can go down to 3lbs if you like......and at that point its a matter of maybe pinching a tire

if you go up to about 7 lbs and above,,,you will slide nice and spin way more

no need to ever go past 10lbs IMO

for trails i usaully run about 4-5 lgs in the rear and 5-6 in the front

if its really rocky,,,i may up it a pound

 

the stockers are 2 ply weakness at its best

replace them with some nice 6-plys when they wear out

what kind of riding do you do? terrain?

also,,,check all tires before each ride

you will be surprised how much they can vary from ride to ride (with low pressure gauge)

equal pressure is also very critical for safety (bike will handle erratically)

 

I don't do any real serious trail riding some rocks and most of the time softer and/or sand type dirt. So far that is where I have been...

 

Of course thank you for the info [img]i/expressions/face-icon-small-smile.gif[/img]

 

when i said 3lbs,,,i meant only the rears (traction)

the fronts need to stay at at least 5 or the handling gets a little shady

 

I think I am going to run about 5-6 lbs all around...

 

If your z400 has the Dunlop Radials you won't notice much of a difference until you get close to 10psi. Radials are designed in such a way that they can be run in various PSI configuration and still give you the same performace for the most part.

A hard radial will still get the same traction as a soft radial and lateral stability will only slightly increase. On a bias ply tire you will notice a bigger difference between a few PSIs than you will on a radial.

 

Thanks I have the stockers so
