Tire inserts are a popular way to allow riders to run lower pressure in their tires. Lower pressure can improve ride quality and traction under many circumstances.
While a tire insert may reduce direct impacts to the rim, it is still possible to experience rim failure due to excessively low tire pressure or extreme impacts. So while rim inserts may help protect your rim, they can't prevent rim failure entirely.
e*thirteen has not evaluated the effectiveness of any particular rim inserts. Our advice is to set your tire pressure appropriately for your weight, riding style, and conditions. Adequate tire pressure is the best way to prevent rim damage, inserts or not!
Running a foam-type insert, or not, will not affect your wheel warranty.
We do not recommend the use of Procore with any of our rims. Procore pressures often exceed the maximum recommend tire pressures for our rims and put stress on the rims in ways they were not designed for. As such using Procore will void your warranty.
