I have a 2008 Ascender , both fronts are wearing on the inside edge. Tires have about 37000 miles on them . At this point I might be able to get about 15000 more out of them . Just wondering at this point should I get it aligned now or just wait until I get new tires down the road . They are pretty worn along these edges but the rest of the tire has good tread left. I think its been like this since new as I have noticed this slow wear on the inside edges almost since I have owned it. It does not pull at all in either direction and goes straight down the road so does this mean the tow in or out is out of spec ? If I get it done now will the alignment be ok on new tires?
