Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?

[Mike Shaljian]

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.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?

[Patrick Moore]

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?

[RBW] Re: How to Determine the "Correct" Tire Pressure?

[Marc40a]

I pump up my tires every morning (every morning that I'm riding, that is).

The larger the tire the less out of spec the pressure is, but I still top them 
off, nonetheless. 

What can I say?  I'm sharing the road with motor vehicles, I'm usually riding 
with a sense of purpose (transportation, usually to work), sometimes at high 
speeds and I want consistent performance. As fun as biking is, it's quite 
serious business. I try to control the factors I can to manage risk and leave 
the rest to wild fate.

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!

[RBW] Re: How to Determine the "Correct" Tire Pressure?

['Tim' via RBW Owners Bunch]

Ha! I came back home to KC and just took a ride on my Roadeo with standard 
sidewall Stampede Pass. I checked the tire pressure with my thumb and 
forefinger gauge. They felt soft (I haven't been on that bike in a couple of 
months) but maybe rideable so thinking about this thread I figured I'd give it 
a go. I hit the wonderful bike path we have here. There are lots of good curves 
and bends and on the first one my tires rolled out from under me, then on a 
subsequent corner I had to go off in the grass because there was an oncoming 
rider and with proper pressure I could have easily stayed on my side but not 
today. The bike felt great on the straightaways though. I checked the pressure 
when I got home and it was 40 rear and 35 front. I normally ride those tires at 
around 80 and 70 with no issues. So I pumped them to 60 and 55 and I'll see how 
they are tomorrow.

[masmojo]

I haven't tried tubeless yet, because of that my test fir tire pressure is if 
when I pop the front wheel over a curb when the rear make contact with said 
curb does the tire compress to the point that I need to worry about snake bite 
flats!? If not I let a little air out,  if it looks like SB could be a problem 
I put air in, until on that bike with those tires I know the pressures I need. 
With the Hetres on my Rawland I am running about 60 rear 50 front. On the

[Marc40a]

My pressures have crept up to where they are from readings of 50 front, 55 
back about a year ago.

Reviewing my notes (kept on my phone), I'm seeing:

 "56/64 seems perfect"

   to "65/59 feels mushy in front using the handlebar bag" 


Just goes to show, this search may never end. ;o)

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?

[NickBull]

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?

[Patrick Moore]

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?

[Mike Shaljian]

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.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?

[Ron Mc]

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?

[Patrick Moore]

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.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?

[Eric Norris]

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.

[RBW] Re: How to Determine the "Correct" Tire Pressure?

[Deacon Patrick]

One way to find out! Grin. I was amazed the difference supple tires made in 
every type of riding (paved, country roads, single track).  I don't know if 
different runs of the QB's had different clearences, but my 38mm Barlow 
passes fit well on my last run (silver) QB.

With abandon,
Patrick

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?

[Patrick Moore]

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.

Patrick Moore, who installed Elk Passes on his '99 gofast, and then swapped
Keos for spds so he can ride the gofast in the dirt.

[RBW] Re: How to Determine the "Correct" Tire Pressure?

[Jeremy Till]

I've been thinking a lot about this recently, not for it's application to 
supple tires per se, but for the inverse: the stiffer the tire, the more 
you have to be careful about tire pressure in order to optimize rolling 
resistance.  I tend to run stiffer tires (Schwalbe Kojak, Marathon Supreme) 
on my everyday rigs because I ride through industrial areas with a lot of 
glass and debris.  I know that you get very few flats even with relatively 
supple tires, Jan, but stiff Schwalbes are what I have arrived at for my 
purposes.  

I used to really love the smooth ride of low pressures, and would run my 
stiff tires really low, often in the 40-50 psi range for the 35mm Kojaks (I 
weigh close to 200 lbs fully clothed and am usually 5-10 lbs in a front 
bag).  But after moving to the flat CA central valley and commuting longer 
distances, I've noticed that they can be kind of a dog.  Since my Kojaks 
are on my Quickbeam (so fixed gear/single speed: https://flic.kr/p/Ett4rD), 
my perceptions are much more in line with Patrick's: my perceived exertion 
for a given gear ratio in a given set of conditions.  So I've recently been 
experimenting with higher pressures, in the 55-70psi range for the Kojaks, 
and they definitely roll better.  In the past couple of weeks I've been 
trying to find a happy medium in the 50-65 psi range.  Not sure I've 
cracked it yet.   

On the other hand, I recently built up an early 80's Medici Pro Strada 
(https://flic.kr/p/DQ9YxP) for the Eroica CA ride in April and I splurged 
on some Grand Bois Cerf EL's for it, and all I can say is that bike feels 
effing *fast*.  Of course, there are a number of things that make it so 
compared to my daily riders: more aerodynamic (less comfortable) position, 
lighter weight (more Al components, plus the fact I'm never carrying a 
commuting load), relatively close-ratio gears well suited to my terrain. 
 But I have been wondering how much is the tires, and if maybe splurging on 
something like the Bon Jon Passes for the QB is worth it.  I downloaded 
Strava on my phone to try and quantify the difference, but so far it's 
inconclusive.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?

[Patrick Moore]

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.

I can tell you what excessively low front tire pressure feels like when 
you make a tight turn: the front end seems to roll out from under you 
and you get a "Holy Crap! What just happened???" feeling.   I've found 
with 32mm and above you can have a slow leak that can get pretty far 
down and not notice anything as long as you're going in a straight line, 
but when you go to make a 90 degree turn the feeling is so unexpected 
and so unusual it really gets your attention.

Re: [RBW] Re: How to Determine the "Correct" Tire Pressure?

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.

Dumb question, but how do you know your tires are collapsing under hard
cornering? What does it feel like? I guess you can't see them, so I'm
wondering what the signs are.

Thank you, Jan. This is great! This matches my experience of riding by

30 psi Barlow Pass on Quickbeam and loaded Thunder Burt Hunqapillar
20 psi day ride TB Hunqapillar (and even with some 60 pound grocery loads,

Even our "smooth" roads are usually chip seal, so lots of wee bumps to
