Do Tubeless Road Tires Loose Air Faster Than Tubes?

I have been pondering this question since I started commuting daily. It seem that my tires are certainly loosing a few pounds a day. I don't have to pump them up daily, but certainly once a week. I have also observed Tubeless tires untouched will be flat in a month or two. Yes, I know it is blasphemy not to ride for weeks, but please keep in mind that I own multiple bikes, and I might not ride every one of them every week.


On the other hand, it has been so long since I have ridden a conventional, tubed road bike clincher, I forget how often they need re-inflation.

So here is the question to my ever growing cadre of readers; What is your experience?  Do you think tubeless tires need inflation more or less often than their tubed counterparts?

  1. Heya!

    I'd say a bit more, at least compared to the Continental tubes i used.

    I've been riding around 100psi, and after two days it barely drops, but 4 days and it's down 10psi for sure, that's with the Fusion3's.

    Given i haven't had a flat in 5 months (riding 4+ days a week, 9-12hrs a week), i'm totally happy with topping off my wheels every few days. =)

  2. I've found it to be pretty much the same as tubed tires. Can't really see any difference in air loss.

    I've left my tubeless bike un-ridden for weeks at a time and never had them go flat (spontaneous deflation)

  3. Yes, I believe that tubeless tires do drop pressure faster than tubed, but they ride better and unless you rip your tire to shreds, no great problem with punctures, just remember to refresh the sealant in the tire every 6 months or so....
