Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
Rene, In my experience the most obvious sign is the noise the tire makes in contact with the ground and it just sounds off. Also the immediate and troubling sign is a lack of confidence when cornering, a feeling as if the bike could easily lose traction and spill over when cornering tight because of a bad contact patch with the road. There's also just a feeling of a loss of control when cornering, like the bike won't track and respond the way you want it to. I agree with Jan Heine's advice of filling them just until they won't "collapse" or have any of these symptoms. I feel like the minimum pressure is a threshold that once you barely cross it, nothing matters. But being under it, you quickly notice the disadvantages. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
Thanks for that. It's interesting that when I swapped my 559 X 35 mm Kojaks (used with tubes) for Compass Elk Passes, the increase in ease of pedaling and "smoothness" was pretty closely imitated by the same Kojaks run tubeless. I didn't ride the Kojaks tubeless long enough to develop a precise opinion, but certainly the Kojaks were far better -- and they're not bad tires to begin with. (I gave up on the Kojaks tubeless because I could not get a consistent seal; only air pressure, and not the bead/carcase itself, kept the bead in place -- rims were tubeless ready Sun/Ringle EQ 21s; with braking surfaces, to link to another recent thread.) Man, Compass extra lights run tubeless must indeed be magical?

Patrick, I recall seeing the 20% figure mentioned by Schwalbe, but I can't find the original source for that anywhere on their webpage now. My anecdotal experience of going from a tubed Schwalbe Super Moto to a tubeless Super Moto setup suggests that this factor is reasonable. Also, nothing like a tubeless setup at 12-14 PSI on 29+ tires! Suspension be damned! Mike -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
On a recent ride in to work, I had a plushy Grand Bois Cypres tire in back but a less-plushy Panracer Pasela in front. I was riding on a bike I haven't ridden for a while that has a somewhat more flexy fork. I remember thinking "This Pasela seems unusually plushy on this bike, it's really nice." Then I went to make a gentle "bear left" turn and discovered why--flat tire. I coasted down and within 30 feet was riding on the rims. It took several days before I felt comfortable turning again, that "Holy Crap, what just happened?" feeling hangs on for awhile.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
The same 60 mm Big Apples that I had run on 24 mm Alex rims at 18/22 or so felt harsher at those pressures on the 44 mm SnoCats; so on the latter I ran them generally at about 16/20, mostly pavement. I'm 170 - 175, and had no problems with them, except for dive in corners on pavement if the front was less than 16. Note that this was all with tubes. FWIW, when I swapped out the Snocats for 30 mm Blunts (at this point, both F Freds, tubeless), I didn't notice any difference in smoothness, but I did notice that the rounder profile on the narrower rims cornered better.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
That sounds like very low pressure for a tire of that volume. I run 60mm Schwalbe Big Ones (64 mm actual) on 45mm rims and they run tubeless at 23 in the front and 26 in the back. I find that any lower than 20 PSI and the tire collapses in corners and handles weird. However, at this pressure (23 PSI happens to be Schwalbe's recc'd minimum pressure) they feel good and supple without any collapsing in corners and generally handling very nicely. I do think the Snakeskin sidewall helps with overall rolling resistance-support-function somehow, too. The key thing is a fatter tire is more supple, so a 60mm tire mounted on a wide rim is going to have more deflection of obstacles anyway. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
Rene, a couple of things you'll feel if your tires are too low - when you turn, it feels like the bike doesn't turn as quickly as you do, and that it keeps turning after you stop. Also too low and you feel or hear the rims shock on bumps. Of course properly aired tires do this until they warm up, but when the pressure is too high, you feel all the chatter in the road surface and you get a different kind of shock on bumps - more through the saddle and the bars.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
One other remark about tire suppleness. I briefly ran Kojaks tubeless and with sealant and found them noticeably faster and smoother in feel than with tubes, so much so that I planned to use them instead of Elk Passes on the '03, because of the greater width for dirt riding. (These Kojaks were Kevlar beaded, and mounted on tubeless ready Sun/Ringle EQ21 rims, but even with these rims, the contact between bead and rim wall remained too iffy for practical ongoing use.) Point being: if you are able to run tires tubeless, that apparently will make them better, all else equal. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
What the Deacon said. I had a low-speed crash a few years ago that was caused by an unintentional experiment in low tire pressure (a slow leak). As I was making a turn, my front wheel squirmed around so much that I lost control and went down. I can also notice too-low pressure when I'm riding on the streets straddling painted pavement lines. Going up and down the slightly raised lines feels funny (which usually alerts me to the fact that I need to fix another leak). Excessive squirminess is the downside (for me) to running large-volume tires at low pressures. --Eric N www.CampyOnly.com CampyOnlyGuy.blogspot.com Twitter: @CampyOnlyGuy > On Mar 10, 2016, at 8:08 AM, Deacon Patrick wrote: > > Squishy.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
If you think that the Kojaks are doggy, ride Tioga City Slickers or the old Avocet city tires of similar appearance: *then* you will feel sluggishness, *and* a narrow range between harsh and squishy! The main point: if the BJPs are like the Elk Passes, yes, they are worth it. With modern sealants I can ride paper thin EPs on goathead infested dirt roads, and believe me, they feel faster than the already highly praised (for speed) Michelin Pro Races *Services Course,* which are themselves supple tires. (Mine were 650C X 23.) I don't know what the BJPs cost, but the $78/tire cost of the EPs is very certainly worth it to me, for my Rivendells. Wonderful frames should have commensurate tires.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?
As the other Patrick said, squishy and even, dangerous. I recall forgetting and somehow letting pressure fall to ~ 10 psi on my 60 mm Big Apples -- fortunately, those, while certainly more supple than many tires, have sidewalls that to some degree support the tire. I didn't really notice until I pulled onto pavement, turned, and felt the bike slip sideways. Another instance: coming down a very steep (costing will easily get you over 40 mph) hill with a tight curve at on of the steepest sections. Fargo, 60 mm Big Apples, probably 17-18 psi on the rear. I decided to try to take the curve at speed -- generally, I am a timid descender. At the apex, the rear sidewalls collapsed under the cornering pressure and the bike's rear wheel slipped sideways -- I was very, very fortunate not to fall onto the right curb at high speed. This was not a skid but the effect of sidewall collapse, perhaps causing a wee bit of sliding. It's interesting to me that not only do supple tires remain smooth and fast at a far wider variety of pressures than do stiffer ones, but that stiffer ones also start feeling "bouncy" under uneven pedaling (as when standing) and "squishy" in corners far more readily under lower pressures than do supple ones -- in fact, stiff tires have a far narrower band of smooth, supportive/stiff, easy rolling than do better ones.

Squishy. Sloppy. Purposefully under inflate your fattest tire (10-15 pounds), then take a few corners slowly, or weave back and forth at higher speeds. You'll feel it and know.
