How low pressure with no rim locks?

pcspecialist · 07-16-2016, 12:46 PM

I now carry a pump with me and was wondering just how low I can deflate the tires to when I make it to the trails?

Without a rim lock, I would guess no lower than 14psi? Has anyone done a significant amount of trail riding any lower than that without problems?

Also, what are you inflating to for on pavement? I'm currently running them between 20 and 22psi.

Not knowing your weight, it is hard to say. I weighed 207 back in my late teens-early twenties, and I ran 16 in the rear. Light weight guys ran 12 or so. I used to drill the rims and put 4 sheet metal screws on either side into the beads.

For me on pavement I ran 28-30. I used Dunlop Trials tires back then.

I added a rim lock to the rear, so I can depressurize to just about whatever I want. in loose stuff, I shoot for 10-12.

Is that one of those internal high pressure tube things? Tube less? I think there called, I will get it if you recommend them

I wonder if those would be a good deal for using those tire plugs. Plugs have saved me literally several times from having to do the spare tire change on my vehicles., long enough to make it to the nearest discount tire which are seemingly on every corner down here.

I had that spoke failure which punctured my rear tube last week and put me out of business on the side of the road

No, the rim lock I installed requires another hole to be drilled in the rim, about the size of the valve stem hole. The rim lock I use is from an old Honda, and it simply clamps the bead to the rim from the inside.

I may do a TUbliss when I've worn out the stock tires, just curious how low of pressure I can get away with until then.

Heck, I was ready for your glowing recommendation

terrain plays a large part
as well as rim type...
If theres rocks stay above 16psi...
as you don't want to bend the rims
bead on a rock...

soft smooth ground go down to 14psi

sand 10 to 12psi

at low preasures it is possable to roll the
tyre & brake the bead seal... pinch the tube...

yer could go lower... but to be safe...

Tubliss..
i have them in my TTR250...
run down to 5/6psi quite often..

a half worn tyre with a tubliss will give as much or more
trackton than a new tyre with a tube...

I've run about 8 PSI on a dirt bike with tubes on sand trails. On a tubeless ATV, 5 PSI on sand trails. I know a lot of people that say you have to put in that slime / repair leak stuff to get the tire to stay on that low. I always have some with me but I don't put in in unless I absolutely have to. Because it's almost impossible to get the tire off afterwards. I've never tried it in a tube but it should seal a leak if there was one.
