Why We Like The Tire Insert Set

The Cush Core Tire Insert Set is a dream come true for riders who have blown countless tires or cracked rims on gnarly rides. It's designed to mount inside of mountain bike tires to divide the inner volume in half, which protects the rim. Dense foam reduces vibration and adds lateral stability, making for a plusher, more supportive ride.


  • Avoid pinch flats and prolong rim life with the Tire Insert Set
  • Increases lateral stability for confident cornering
  • Specially designed tubeless air valves included
  • Pro fits rims with internal diameter of 22-35mm
  • Pro is ideal for 2.1-2.5in tires
  • Plus fits rims with internal diameter of 32-45mm
  • Plus is ideal for 2.6-3in tires
  • Item #CCU0006

I've put it through the wringer

Love these guys!! Been wondering if they were worth it and after a season of running them along with my the rest of my crew rocking them too; we’ve added more riding time with less flats along with lower pressures. Traction is the name of the new game here! Glad to have them along for the ride!

Worst MTB product I have ever purchased

I've used it several times

I actually didn't have too much trouble installing these. I threw them in a Maxxis DHF 2.6 front and an Aggressor 2.5 rear. My issue was the performance, or really lack there of. All I encountered were a slew of disadvantages. First off, they shrink the volume of your tire. People have mentioned that this makes them more "progressive." I just found that they were bouncing off of everything even after I kept dropping the pressure. I ended up with 17psi front and 18psi rear and they were still bouncing off of rocks and not holding a line (normally I run 20/23psi). Next is that I could really feel the extra weight in the front wheel on steep technical climbs. My HD4 is relatively slack but with a 35mm stem, the steering always felt really precise... until cushcore went in. Much more wandering and tire flop. Didn't make it up many of the tech sections that I regularly clear. At the end of my ride, I slowly lost air to the point I had to get off the bike. Replacing a flat on the trail would be a complete nightmare and nearly impossible. Luckily I was able to get a ride home. Turns out my rim tape was damaged due to trying to jam the bead to the center of the rim on install. So 2+ hrs later I finally got the cushcore pulled, the rim tape replaced after vigorous cleaning, and my tires back on. Never again
