I don't get as many miles as you report; on the rear, I probably get 1,500 miles on a tire, probably 50% more than without the tire liners. This may be because they are 20" tires.
Installing the liners is a bit of a challenge, but I've been using double-sided tape rated for "outdoor use" to keep them in place while mounting the tires (8 one-inch strips).
