Last year I inquired about Nailguards for a 14 inch rim and was told they don't make them in 14 anymore, but was able to get 15 inch for my pickup. Now the Uniroyal dealer tells me they are being (or have been) discontinued. Bummer. Seems to me a great tire. I realize flats are rare, but they do occur and usually at the most inconvenient time (anytime it inconvenient, right ). Anyway, I hope something comes out to replace it for those of us who want one less thing to worry about.
