Not looking for a debate on whether or not tubeless is a good idea. Anyone with experience, please chime in with your thoughts on finding the proper tire pressures.
I'm riding with 28 Pirelli P zeros. Wheels are Bontrager Aeolus RSL 37 (21mm internal width, hooked rims) on a 2022 Emonda. Using Stan's sealant.
The chart that came with the Pirelli's said for my weight (~178lb) they recommended 90 psi. That seems high to me.
One of the benefits of tubeless is enjoying a more plush ride at lower pressures. 90psi isn't what I'd call low pressure.
I've also heard anecdotally that if you ride with high tire pressure, if the tire gets a hole, the high pressure will result in the sealant squirting out too fast to create a seal. Not sure if that's true or not.
I've found a few websites that seem to all use the same basic calculator for tubeless tire, such as on SRAM's site for Zipp:
https://axs.sram.com/guides/tire/pressure
That calculator recommends pressures for me in the mid to upper 60's.
What's the best way to find proper pressures? Concerned about safety and having the sealant do its job if tires get punctured. Not so obsessed with getting the absolute lowest rolling resistance.
Thanks in advance.
