Default 26mm molded inserts

I am looking for molded foam tire inserts for 26mm tires. I can find 24mm inserts all day long, but am unable to locate any 26mm. I found on HPI's website that they used to make them, but they have discontiued them. Does anyone know where to find them? I am desperate as I am tired of wearing the inner edges of my tires by having to run the 24mm inserts. Thanks.

I've used the 24mm inserts with HPI 26mm tires, and never experienced any problems with irregular tire wear. You might want to change your suspension geometry (less negative camber) to alleviate the problem, or switch to HPI belted tires. However, if you're using open cell foam inserts, you'll wear the inside edge of the tires because the inserts migrate to the outside of the wheel after a short time. Switching to the firmer (yet narrower) insert will resolve the problem, since it will stay centered within the tire/wheel assembly.

Sweep inserts are 26mm are they not?

If you're referring to the 1/10 touring inserts, they're 24mm wide.

I certainly appreciate the input. I am running 1.5 degrees front neg. camber, and 1 degree rear. The tire wear only appears in the right front tire. I am currently using Sorex soft 24mm inserts with HPI non belted x-patterns. We are racing on a pretty high grip parking lot in a counter clockwise direction. The tire wear I am experiencing is coming from a long left handed sweeper. Would a harder 24mm insert help here? Belted x patterns? Or do I just have to realize that our lay out will eat the right side tires?

No, unfortunately they are 24mm inserts.

Both the belted HPI tires and a firmer insert (HPI red or green) will help with inner shoulder tire wear, but there will be some inner shoulder wear on any outside front tire when a track has a long, high speed sweeper.
