_Frequently Asked Questions


Absolutely. The feeling of riding with CushCore is not a subtle difference from standard tubeless tires. Even novice ers notice the differences right away. It is a confidence- inspiring riding experience. Need evidence? Check out the PROVEN BENEFITS.

Both Standard and Plus-sized inserts will fit a 2.6″ tire. We recommend selecting the insert that is most appropriate for your rim’s inner width. Use standard for an inner width of 33mm or less. Use Plus for 34mm or wider.

See fitment specifications HERE.  Within the size recommendations, CushCore works well with every rim and tire on the market. *Asymmetric Rims – CushCore will fit asymmetric rims and we recommend starting with the bead furthest from the rim channel for installation. This leaves the final bead right next to the rim channel and will make it easier to drop the bead in the rim channel to finish off your install.

Installing CushCore is not difficult, but it is different. We highly recommend watching the Installation Video before you begin. Installation by a first-time user should require no more than 30 minutes.  Installation by an experienced user takes 5-10 minutes. If you need help, contact us for assistance.

Yes.  CushCore is compatible with all sealants.

It is still possible to get a flat with CushCore – for example, in the case of a tire sidewall slice.  While CushCore is not intended to be a run-flat tire, it is possible to “limp home” short distances with reduced risk of rim damage.  Trailside repair is also possible using the same approach riders use with standard tubeless.  Tire plugs are a great option. 

Tire choice is a personal preference, and the best choice for you depends on several variables.  In general, CushCore makes it possible to run lighter, faster-rolling tires without sacrificing lateral stability, impact absorption capacity, or flat resistance.  For that reason we suggest trying a tire in a lighter weight class than you normally use – for example, a 750 gram tire instead of an 950 gram tire.  If you are already using a lightweight tire, try reducing tire pressure as described below.

Many riders prefer to run 1-5 psi less tire pressure with CushCore. The ideal pressure depends largely on your starting point – your normal air pressure with standard tubeless. Riders who already run low pressures (for example, 20 front and 23 rear) have less room to adjust than riders who normally run 30 or 35 psi. Excessively low tire pressures increase the risk of flats or wheel damage. We encourage you to experiment and find your own preferred setting. Start at your normal tire pressure, then drop in 1 psi increments until you find the sweet spot for your riding conditions.

CushCore inserts are extremely durable.  Our foam is engineered to withstand repeated pounding without degradation, and it is not affected by tire sealant.  Typically a set lasts riders a couple years, though the ultimate service life depends on your riding frequency, tire pressure, terrain, and other factors.
