Tire life is really dependent on your driving conditions and what you put on. What you put on is also restricted by the tire size that you're replacing. Any wear ratings that are advertised are always "suggested", and many are hit-and-miss when it comes to achieving what is advertised.
For daily driving, I mainly use performance tires because I have another set for winter and mainly travel on highways. I average about 36,000 miles on a set.
For better input, what is the tire size you're looking at? Some of the tires out there that folks here may recommend may or may not be available for your application. So, you'd better post it
