New Item!  These are both a work in progress and experimental.  Your mileage with these may vary.  So I strongly suggest when trying these out you only order a couple of them initially to see if these will work for you.  It is very difficult for me to get the width the same around the entire circumference of the "tire" due to the nature of cutting rubber tubing.  So you will notice one part of the tire will be wider than the other.  I have not had any issues with this.  
 
These are replacement "tires" for the melted pinch rollers that were an issue with early 8 track tapes.  Please note, these are the "tires" only.  They do not come with the plastic hub.  You will need to clean off the old crumbling gooey rubber from your current plastic hub.
 
These press onto that hub.  You will need some kind of rubber safe lubricant to get these onto the hub, it is a tight fit! 
 
Personally I use a "dry" spray silicone lubricant available at any hardware store.  This lubricant will dry over time.  You will need to lubricate the outher edge of the plastic hub where the tire will be slipping over it (just the outer edge, not the inner part where the tire will rest on the hub). And then press the tire onto the hub (I use my thumb to get it started on the hub then use the palm of my hand to finish pressing it on).
 
These are sold in 2 different sizes so choose carefully.  This listing is for the narrower GRT/Module 8 replacement tire.
