My truck is three years old, lives outside, and has 24k on it. While I know the sun is harsh here, I was surprised to see my tires cracking. I noticed this when I gave it a wash yesterday.

All 4 tires are the same. I don’t use tire dressing, and just wipe them down with a microfiber sponge when I wash the truck. I guess it’s time for a lift and new tires.
