The CushCore 27.5 Plus Tyre Inserts are designed for aggressive mountain bikers and trail riders running plus-sized setups who want to maximize traction and rim protection. By acting as a dynamic suspension system within your tyre, these inserts offer a significantly smoother ride and increased impact resistance; however, the installation process is notoriously challenging and requires patience or specialized tools.

The proprietary polyolefin foam is highly durable and designed to last through the life of multiple tyres, provided it is not cut by sharp debris.
Yes, many riders find they can run 2–5 PSI lower than their usual pressure due to the extra sidewall stability provided by the insert.
The set includes 2 tyre inserts, 2 44mm Presta air valves, a valve core tool, installation instructions, and rim stickers.
Ensure the insert is pushed deep into the center channel of the rim and use generous amounts of tyre lubricant.
Check that you are using the included CushCore valve and that the valve core is not clogged with sealant.
Experiment with slightly higher tyre pressures to find the balance between damping and rolling resistance.
Proper installation is critical for the best results.
Because the material is closed-cell, it does not absorb sealant, so you do not need to replace the insert when changing tyres. Simply wipe it clean and inspect for debris before reinstalling.
