Hello. I'm currently deciding on which rear tire should I buy. I'm currently running an onza ibex 26*2.4 with 50% tread life and I want to buy a new one because I didn't notice that this tire put a small hole in my frame due to constant rubbing of the side knobs. Since brand new maxxis 26er dhr 2 is not available in my area. There's someone who is offering a 2nd hand maxxis DHR 2 with 70-80% treadlife while the other offers a brand new DHF. So what tire should I buy for rear?
