I had a Tubeless puncture that (after a while and a lot of spurting) sealed itself today. I normally run 80psi at 101kg on 28mm Hutchison (really long tyre name, storm compound 11 in there somewhere).
I stuck a bit more air in but my mini pump is a bit poor and I only had 10km or so to go.
It was clearly lower pressure than I normally run but actually felt OK; I checked when I got home and it was about 58psi. I didn’t hammer the last section home so I have no idea on times, but it made me think about maybe trying say 70psi for a while.
As previously mentioned in the thread Jan Heime here and elsewhere throughout his tech info has loads of verifiable data and tests showing lower pressure (outside of a velodrome) is beneficial.
I know lower pressures are beneficial, but I don't like how they feel and am happy to ride my bike with almost solid tyres, same as TJ.
I don't like standing climbs with low pressures, I don't like skid stopping with low pressures, I don't like cornering with low pressures.
I don't like riding with too low pressures either.
But with modern tyres and rims, what constitutes 'too low' is a lot lower than it used to be.

Sealant works better at lower pressures, so more likely to seal. Also - use anchovies.
Most folk would think I run far too high pressures. We ain’t all the same
I’m the other way and run low pressures. Not road bike though. Stooge and WTB 40’s I have nine PSI up front and 13 back. Running a pair of Teravail Coronado 3.0 with the light casing. Might have to go to low double digits up front after I got a bit of squirm on a sharp corner.
Some of the pressures mentioned on here are obscene, 60! 😱

Left the pack in the bar bag on my gravel bike. What anchovies for road bike that don’t take up much space?

This is a road tubeless thread…
my (35mm, marathon plus tyres) showed 21 psi last time I checked. Normally pump them up to 40 then leave them till the handling goes funny and the squelch on sprints. I'm 100kg with my bike and gear on. They feel a little quicker when pumped up, but I don't notice going slower as they drop.
I experimented tonight, 70kgs, running 28mm tubeless tyres on a 21mm internal rim. With a power meter. 8.5kg bike. I had 55psi in and there was no difference in my average speed. I didn’t feel a squirm or a rim ding, but I wasn’t as confident in the faster corners.
I only tried pushing hard on a couple of segments, but don’t think there was any speed difference.
I might try this at lower pressures later in the week. My local short loop is 27 miles, I normally average anywhere between 19 and 21mph on it. Will try at 50psi on 27mm tyres(new Challenge Strada tyres due in the next day or so).
This is my normal bike with my normal tyres, just new ones. Ive done this loop countless times in all winds. I very rarely get any new PB’s.
