Sand tire psi

So I know this subject has been beat up... Just looking for someone that has experience in riding in sand with a sand tire. Should my psi be at

A. 15 psi per manufacture recommendations

B. 10 psi aired down for more traction

C. 12.5 psi somewhere in between

Or D. ???



10-12 psi only if there are no rocks or sharp edges.


Edit: those pressure recommendations are for a knobby tire.

I never found that lower pressure in a bike paddle did anything beneficial traction-wise. 15psi

This is a paddle tire or a soft terrain knobby?

Sand paddle tire... When rolling the bike it feels like you got a flat tire lol! And I'm going to pismo beach... It should just be sandy.

Pismo dunes are just sand. You don't even need a paddle tire for there but it does help.

low pressure tears the scoops off easier. i dont get real technical about it as long as its between 15-20 psi

12-14 turbo II 8 cup on 01 cr500.  Front is a Dunlop MX-81 hard terrain set at 6 psig.  Don't slam it hard in a lot of rocks.  This Dunlop has the widest measured width I could find in a MX 21 front.  Aired down so low because it has a super stiff sidewall.  I also run the same thing on my kids 450R,  it is by far the best front sand Tire I have ever ran and I have ran a lot, BS, Michelin, metzler, peirelli etc.  This one floats best and still corners great.  Now that it is discontinued not sure what I will do when it and the two extras I bought are gone.  The 450R has a Michelin Sand 4 on the back and it hooks up almost as good as a paddle but handles tons better and still 12-14 psig.

i used to run 30 psi in my paddle tires.

I do run double bead locks to avoid slipping the tire

ive found 2 rim locks to be unesecarry. maybe i just dont have enough power

I was slipping the tire with one.  Sometimes it's the consistency of the sand or lack of sand! or the power vs the riders weight.  Whatever it was it happened and tore the valve stem, once was enough for me to make it worth the second one.

I remember in the fox movie "fly" damon bradshaw said he was running about 13. haha so thats what i always tried to run. I usually never paid much attention. the shop I had swap the paddle all the time aired it up and i just ran it at whatever it was.....

I know this is an old topic, but I strongly disagree.  You will get the best traction with no valve in the tire.  I run the tubliss setup so I can get away with this.  Otherwise, 2 or 3 PSI is good.  This is for knobby tires or paddles.  Believe it or not, there is a massive difference between a paddle at 8 psi and 2 psi.  If you look at all the guys that drag race in sand for money, you can see that their tires are very low or completely flat.  You can prove this to yourself by finding a hill you can't climb with 8 psi- take it down to 2 and there will be a huge difference.

      So Been rebuilding my bike and the rubber mallet just "wouldn't cut it"!!!!
      I had to pry managed to sand down it all looked flat but this seems a bit gappy.

      This is only on the outer edge but I can help worry this is going to leak or get shit into the engine.
      Any help or advice would be awesome thanks

      Hey guys, so cant find much online about cr 250r enduro conversions (nothing recent) so im wondering if it is an option or not. I currently have a crf 250x 2009 and a XR 650r. If i want a 2 stroke enduro but want to stick with the honda line up, is a 2007 or 2005 honda cr 250r a good option. and if so what would need to be done to it to get it up to spec for trail and enduro riding. Thanks very much

      If you own a 2 stroke dirtbike,please reply once. Im just wondering how many people on this site have them.

      Note: This specifically applies to the '92 - '01 CR250 engine, but it should be adaptable to any 2-stroke. The basic idea is to pull the carb and exhaust, plug one and pressurize the engine through the other to look for leaks.
      It's very important to pressure test a 2-stroke after it's assembled. The reason is that a 2-stroke gets it's lube through the pre-mix. An air leak means your engine can run lean. Lean means too little fuel. Too little fuel means too little lube. Too little lube means death to your engine. So here we go.
      First, you need to pull the seat, tank, shock, carb and pipe. Everything you need (other than a tire pump) is shown below.

      The assembly below is basically a 1-3/4" PVC plug (same OD as the intake pipe ID) that is transitioned down to a 0-15 psi gauge, a shut-off valve and a Schrader valve (to connect a tire pump). The 1-3/4" PVC plug is a tight fit in the intake pipe, but it'll fit with enough persuasion. I used yellow heavy duty pipe tape (made for gas systems) to put everything together. I don't have all the technical names for everything, but if you take the pictures to a hardware store, they should be able to help you piece it together.

      The item below is an adjustable rubber freeze plug. They are available at automotive parts stores in various sizes, but the closest one I could make work was a 1-3/4" version. You tighten the nut which squeezes two metal plates together which squeezes and expands the rubber piece between the plates. You have to tighten it a lot, but it makes a good seal in the exhaust port.

      Before you install everything, make sure that the piston is at BDC (so that all the ports are open), the spark plug is installed and all other components are properly tightened. Below, you can see the gauge/valve assembly installed in the intake pipe. Make sure to tighten your intake pipe hose clamp tightly as the pressure will tend to push the assembly out.

      Below, you can see the freeze plug installed in the exhaust port.

      Once you have everything installed as shown, use a tire pump to pressurize the engine to 6 - 8 psi, then close the valve and watch the gauge for any pressure drop over a 5 - 10 minute period. A well sealed engine will hold pressure with no observable pressure drop for 10 minutes easily.
      One common "leak" in a healthy '92 - '01 CR250 engine (and probably other types) is through the powervalve linkage. It probably doesn't affect performance, but it'll sure throw your leak measurements off. To avoid leaks, make sure the powervalve linkage is correctly lubed (per the Service Manual) with grease and Moly 60 Paste during assembly.
      If your engine holds pressure with no observable drop for 10 minutes, you're good to go. If the pressure drops 2 - 3 psi or more over 10 minutes, spray soapy water all around the pressure test parts first to check for leaks there. If you find none on the test setup, start spraying the soapy water around the base gasket, head gasket, center gasket etc. Any pressure drop of less than 2 psi over 10 minutes is your call, but I'd definitely fix it.
      I've had really good results by using Permatex Copper Gasket Sealant on the base gasket, PV cover gasket and reed cage gasket. I don't use anything on the head gasket.

      What value would you say a 1986 cr250 with a freshly plated cylinder and new top end, newer tires, newer chain & sprockets, in overall very good condition?
      I picked up the bike (cheap) a month or so ago in need of cylinder replating & top end. Apparently the headgasket blew internally scouring the cylinder. The crank feels good and the bike is very clean/good condition.
      I havent put the bike together yet (too busy to ship cylinder and order parts), but figure I would have a total of $600 (including bike cost) to get it into good running cond.
      A friend wants to buy it as-is for his 15 yr old 200# kid. What value wouldyou put on it in As-is condition vs with a fresh engine?
