I bought some tires a couple of years ago and have noticed some cracks forming. The tires are Yokohoma's Geolanders ats. 33x12.5x15 I am planning on moving to Oklahoma and am questioning the shape of these tires. I have around 3K miles on them still all but brand new. I am going to try and post a picture so please bare with me. The cracks are most noticeable towards the bottom of the picture that is on the right side. Do you think these might be under warranty still?
