Insertos

A bike tyre insert is a lightweight foam structure that sits inside a
tubeless tire between the tyre and rim. It helps protect the rim from impacts,
reduces the risk of pinch flats, and supports the tire during hard cornering
efforts.

Vittoria Air-Liners are designed for specific riding disciplines, from
road and gravel to cross-country, trail, enduro and downhill. Each model
balances weight, protection and tire support for its intended use. Because
Air-Liners use a closed-cell or waterproof construction, they do not absorb
tubeless sealant, helping keep sealant where it is needed while making the
insert easier to clean and reuse.

Bike tire inserts are a worthwhile investment for riders who want
greater rim protection, fewer pinch flats, more tire support, or the ability to
ride at lower pressures.

Tire inserts create a protective layer between the tire and rim. It can
also support the tire during cornering, reduce burping and provide run-flat
support after pressure loss.

No tire insert can prevent every puncture, but an insert can reduce
impact-related damage such as rim strikes, pinch flats and snake-bite
punctures.

Tubeless sealant remains responsible for sealing many small tread
punctures, while the insert helps protect the rim and tire during harder
impacts.

Yes. All Vittoria Air-Liner models provide run-flat support, allowing
you to continue riding cautiously after a loss of tire pressure.

The recommended distance varies by model. Some Air-Liners provide up to
50 kilometers, or about 30 miles. When relying on an Air-Liner for run flat
protection, reduce speed, avoid hard impacts and repair the tyre as soon as
possible.

Yes. A tire insert adds rim protection and sidewall support, allowing
many riders to safely experiment with lower tire pressures.

Lower pressure can improve traction, comfort and the tire’s ability to
conform to uneven terrain. The insert also helps reduce tIre folding and
burping during hard cornering. Pressure should still be adjusted for rider
weight, tire volume, rim width, terrain and riding style.

Vittoria offers discipline-specific Air-Liners for road, gravel, cyclocross, XC, trail, enduro, downhill and e-bike riding. This allows riders to choose the protection they need without carrying unnecessary rotational weight.

Depending on the model, Air-Liner benefits include:

• Lightweight, discipline-specific construction
• Complete-loop designs with no cutting or joining
• Included multiway tubeless valve
• Foam or coatings designed not to absorb sealant
• Sidewall and bead support that helps reduce tire burping
• Run-flat support after pressure loss
• Protection designed to preserve normal tire handling and responsiveness

Some tire inserts can be difficult to install because their thick,
high-volume profiles create a very tight fit between the tIre and rim. Vittoria
Air-Liners are designed to simplify installation while still providing the
support and protection required for each riding discipline.

Installation difficulty still depends on the tire-and-rim combination,
but Vittoria’s discipline-specific shapes and densities help avoid adding more
material than necessary.

Choose an Air-Liner based on your riding discipline, wheel size, tire width, rim width and desired level of protection.
