I replaced the old tires of my bicycle because I had daily problems with punctured tires. Since I put these specific ones on almost 2 months ago, they haven't punctured even once. The thorns that used to puncture my old tires and cause holes in the inner tubes, either break or don't reach the inner tube when I run over them. I'm not an expert to comment on grip or comfort (I don't have much experience in these matters), but in terms of durability, I am very satisfied.
