Tubeless vs tubed tyre pressure
The casing of your tyre and what's inside it both change the ideal pressure. Tubeless, latex and butyl all behave differently — here's how to think about it and how to convert between them.
Why tubeless runs lower
With no inner tube, there is nothing to pinch between the casing and the rim on hard hits. That means you can drop pressure 8–15% compared to the same tyre run with a butyl tube, without inviting snakebite flats. Lower pressure improves grip, comfort and — on real-world rough surfaces — rolling resistance.
Conversion table
| Tubeless | Latex tube | Butyl tube |
|---|---|---|
| 50 psi | 53 psi | 57 psi |
| 60 psi | 64 psi | 68 psi |
| 70 psi | 74 psi | 79 psi |
| 80 psi | 85 psi | 91 psi |
| 90 psi | 95 psi | 102 psi |
Approximate equivalents. Add ~6% for latex and ~13% for butyl tubes compared to a tubeless baseline.
Where latex fits
Latex tubes are supple and roll closer to tubeless than butyl does, which makes them a good upgrade for hooked rims where tubeless setup is fiddly. The trade-off is permeability — latex loses pressure overnight, so check it before every ride.
When tubeless isn't the answer
Hooked rims with narrow tyres (≤25 mm), heavy track use, and any rim that isn't tubeless-compatible are still better off with a good latex or butyl tube. The casing and rim system have to be designed together.
