I'm driving my 2013 Subaru Outback up an 8 mile dirt road to the top of a mountain where I live. I do this pretty much twice a day, to and from work to go up and down the mountain to the pavement and on another 40-50 miles to work and back. I've got Continental tires now and have had them for about one year (bought my Outback in 2012), moved up here to the Ozarks and have been driving like the above said for a year. I've got about 23k miles on the outback now, and it seems that the treads are now going and I'm getting a hole every other week from rocks etc. What with this being the case I have now been looking into getting some better tires, however am running into the difficulty of finding a good off roading tire that is in a smaller ply. I'm told all I can go to is a 5ply. I have no idea where to start, what the recommended brands are or who has the best pricing on the. Moseyed to this forum for your guys' help. Please give me some suggestions. The tire size on the car currently is 1225/60 R 17 98T. Really what I am looking to find is a good tire that I can keep longer than 20k miles. Again Please Help!
