My last set of tires I bought were the cheapest I could find at my LBS; I was getting flats everyday from the smallest things -- unbelievably small bits of wire.

So I decided to upgrade my tires so I wouldn't waste so much money on patch kits. Bought Bontrager (700 x 38c) H2 HARD-CASE Triple Flat Protection. Well, I don't have as many flats, but I do get them periodically (but far from daily -- so that's good), but now they are from really big things, things so big they put a huge gash in my tire. No problem I just patch up the inside tire and all's good.

Until yesterday. I got a flat from what looked like a small nail, but as I pulled it out of my tire and inspected it, it turned out to be a piece of splintered wood, this was no normal splinter, very tough, but small -- about 1" long and had the diameter of ~2mm.

Question: What tire have you had the most luck with in preventing flats? BTW, I don't use those liners inside the tires; tried them with no luck.
