Out of my own curiosity, is it normal with tubeless tires to need to add air each day or second day? I guess I had thought that they maintain constant pressure better than a normal tubed tire.

If it's not normal I'll go through the install again, but I have plenty of sealant, my valve cores are tight, and it appears that my rim strip is secure.

I have never had tubeless, but my understanding of mtb tubeless is that they lose air quickly and you need to pump them up daily. That is with them running at a lower pressure. I would think road bike tires would lose just as fast.

A correctly installed tubeless system will hold air for a very long time and should not leak. My road tires lose about 1 bar/week and mountain front tire loses 1bar/6months. The mountain rear tire will empty in a week so I need to do the install again.
Road tires might lose pressure faster due to the higher overall pressures

I've had some lose air, and some not. My current training wheels (Bontrager Race w/ Bontrager R2) lose about 10-15psi overnight when inflated to 90/80. I should probably add some sealant one of these days and see if that changes things.

ok thanks. these are similar, Bontrager Race Light with R2's. I did add sealant probably have about 1.5oz per wheel. Loss is in the same neighborhood about 10-15psi per night.

Just wanted to make sure it was normal

I pump my tubeless road tires up every ride, they always drop a little bit. they don't lose any while riding with the sealant spinning around all the time though.

Yep, depends on the wheels and on the tires. Some lose and some don't, no big deal. Sealant usually solves it completely.

thanks folks!

I lose a couple of psi on my tubeless mtb tires every two weeks.

I loose a few lbs every day on my tubes and tubeless. perhaps it is the intense heat here in AZ.
