Gemplers has the tire liners and they should work with the glass etc. They are just ground down old tires that drop inside your current tires. It is also recommended that you use old inner tubes as a liner between the liners and the current inner tube. Just remember to check your tires for damage on a regular interval to make sure that an partially impeded item does not work it's way all, the way through the liner.
Those liners are about another 3/8 to 1/2 inch thick at the bottom and tapering off to the sides as they go up towards the edges of the rim.
I still have a new set and once I get a flat, they will get mounted. Currently I do not desire to pay for mounting liners when I don't need them. Yet.
