This past weekend I was washing my truck and I noticed the 2 front tires are wearing unevenly. Both the inner walls are wearing out much faster than the remaining parts of the tire. I've just bought this truck last August and only have about 17k miles on her, she is bone stock. My first thought was the alignment, but it's been straight ever since I bought her. The only thing I can think of is that I've taken her off-roading a couple times, nothing major, no rock crawling, just a bit of medium speed desert stuff— no jumps. Could the shocks be blown? I'd like to think Toyota's TRD off-road shocks would be much beefier than what I've done to her so far. Any advice would be greatly appreciated. Thanks.
