I will soon be on my 3rd set of NT05's in 275/35 18 and I am quite pleased with them.I have gotten about 25 hours out of each set which is about 10-12 days.I do flip them on the rims at about 50% life to keep them squared up to maximize their life.They work better as they wear but they are not a very good tire in the rain or colder so I use my stock 19'" PS2's for that use.Overall I am very happy with the NT05's as they do stand up quite well to my level of abuse that I have been known to do to my tires
