Hello everyone, I bought an 06 xterra OR last month and I have been trolling this board ever since. Of all the xterra boards I have been reading this so far has been the best. Thanks all for the research and information that you have shared. So now my question. Is there a site that will give me a complete break down of specs for off-road tires? Some of the manufactures such as Mickey thompson doesn't include things like speed ratings. Many of the sites for tire shops do not list all brands of off road tires (selection at discount tires is different than tirerack.com). Specialty shops such as 4 wheel parts will give you diameter and width but not load ratings or speed ratings. I guess I am hoping there is a one stop shop website that gives a complete break of off road/all terrain tires much the way tirerack.com is set up. I did a search for this information but could not find anything so if I missed the topic else where please link the thread in your reply.
