First, I live in the desert, with most of the trails I ride are dirt, with small rocks. Ocassionally on the trail there are larger jagged rocks. I don’t ride hard, as just like getting out and admiring the scenery. The rear tires on my car are getting pretty worn. The front are still good, with a couple of plugs. I’m sure that they are original, 2013 model with 2,800 miles, and 230 hours.
Now for my question. Should I go ahead and replace all 4 tires, or just the two rear that are really showing their wear?
