Pretty hard since each rider-bike-conditions can be quite different and the test should be in real world conditions. I usually search for any reviews of tires I am considering. Here is a sample on your tire, http://www.roadbikereview.com/cat/wh...3_2489crx.aspx

Over the years, my most reliable, quality tire has been from Continental, so now, I usually start there for my bikes.

I think some places have a short satisfaction guarantee, I know REI is pretty good about that sort of thing.
