Mountain Board Tires Question

If i am on grass, what should my tire pressure be on my landboard? :smilegrin:

If you are grass? :lol:

I think that you'd want to go with a higher tire pressure.....maybe 50 psi or so on grass to keep from sinking in. Grass surfaces are obviously not all the same. I find that riding on my local fields is a total pain in the A$$ because they don't keep them mowed very short and the ground is a bit soft and spongy. Mix that with inland winds and it is pretty challenging for me to get going even for a downwind run.

Overall I'd say harder tires for hard grass fields and I go with softer tires on sand for more traction and float....especially softer sand.

LOL i edited. my bad ........Well I got an MBS Board and i just filled tires to 25psi and they are as hard as a rock. m afraid to go 50psi. arn't they gonna explode?:lol:

I never use a gauge to check the tire pressure but I always blow the tires up so they are firm to the thumb - meaning I can push hard with my thumb and the tires feel solid.

I especially like them that way on grass though maybe a little softer on sand sometimes. But for the most part I like my tires hard.

If they area too soft and you do power slides, you can crack the side walls as the tire can be squished over the rim.

At least that's what happed to my Mak tires - now I'm riding T1s and they have been holding well - fully inflated to the touch.

You need to find the balance between rolling resistance and traction for the surface you are on. Higher tire pressure reduces rolling resistance and traction, so you go faster, but you get a harsher ride and could bounce more on surface roughness. A heavier rider will need a higher pressure than a lighter rider too.

My MBS Comp 16 tires say inflate to 60 psi, so I use a gauge to see that I don't go past 60. I am 200lb and like to keep them at 50-60 psi for longer grass or wet pitches in the Spring and 30-40 psi for short grass or hard packed surfaces. They start to not feel firm at around 25 psi.
