Which to be fair is far less grief than tubeless, gives a good result and means you can carry on swapping tyres without too much hastle

Ripped this from another MTB bike I frequent,

Don't know if this is any use........

Stan’s NoTubes is the only company I can find that provides anything close to useful information. As a result, I’m sure the poor sod that published it is not longer with the company. The recommendation is based on size 2.0-2.2 tires:

Rich O’Neil of Stan’s NoTubes sent me:

To determine a starting tire pressure when running NoTubes tires with our ZTR rims use this simple formula:

Front tire pressure in PSI: (Rider weight / 7 ) – 1
Rear tire pressure in PSI : (Rider weight / 7 ) + 2



While Stan’s NoTubes says that this is just for those people using their system, it seems pretty darn accurate for just about any tubeless set-up, based on all information I can collect from conversations with people who have used tubeless tires for years, and from many hours of culling information from the Internet.

I am going to try the following, based on Stan’s NoTubes recommendations, and a 15% increase in PSI for trails with a lot of sharp rocks/roots:

Tire pressure chart for rider weight. Uses Stan's NoTubes recommendations, with a 15% kicker for rocks/roots.

If you had tubeless tyres on your bike we'll have to tether you to the ground as it would float away, strong winds and your be off over the hedge tops 

Get some slime tubes to add weight....

I'm waiting for my tubeless wheels to be built, hopefully have them by Saturday. I've been spectical about tubeless for ages now but having read up and got advise I'm beginning to understand it all now.

Buying a tyre took the longest, everytime I found a tyre I liked, I found something wrong with it, bad tread pattern, sidewalls not thick enough, wasn't folding, measured up too small or too big and general lack of info on some tyres.

In the end I wnet with a Michelin Wild Rock'R 2.5, shame it was a wire bead and weighed a tonne but I'm playing it safe then I'll go with lighter tyres. I'm also under the impression Michelin's inflate really easy and keep their air the longest and the sidewalls are seroiusly thick from when I used them years ago for trials.

when i jet wash my mud x's you can see the stans sealant coming through what would have been a puncture if i'd have been running tubes, there must be a 50+ in each wheel, but i've never had a flat in the 2 years that they have been tubeless and the never lose more than around 5psi over a week if not used.
just make sure when you buy your valves, if presta, that the have removable cores so you can add the sealant via the valve stem when the tyre bead has been seated and top it up every six months or so. i use a 5ml syringe to inject the sealant, the kind you give kiddies medicine with. then its fit and forget!

Ordered sealant, 21mm yellow rim strip and 2 universal 35mm valve stems.
Now thinking of buying a syringe from pharmacy instead of the one they sell.
