DOES SEALANT EFFECT FOAM INSERTS?
Flat Tire Defender® foam inserts are made of closed cell material so they keep the sealant from penetrating and affecting the foam insert performance. However, tire sealant has a tendency to ‘cling’ especially as it dries. So you may see some sealant build up on the foam insert after use, much like the sealant build up you see on the inside of your tire after use. We recommend removing the inserts every 3-4 weeks for cleaning & changing the tire sealant.
TIRE PRESSURE GUIDES *
Based on Flat Tire Defender field testing, we’ve found on average, tire pressure can be reduced approximately 10% from a tubeless tire pressure without foam inserts.
FTD II (27.5″ & 29″): Range 24psi to 29psi
FTD II (E-Bike): Range 26psi to 32psi
*Tire pressure is very difficult to recommend due to the number of variables in tire brand, tire casing structure, rubber compound, rim brand, rim material, rim inner width, bike/suspension set up, rider ability, terrain, etc.
Flat Tire Defender has performed extensive field testing using a wide range of tire pressures to best determine a PSI guide. Please remembered this is only a guide. It’s up to each Flat Tire Defender user to determine the proper tire inflation pressure that best suits their choice of tire, rim, terrain, bike set up, suspension set up and riding ability.
