These are the tires on my truck, see the picture. Based on the picture, would you replace these tires? All 4 look basically the same. In slick road conditions they slide around and I have to drive much, much slower.
If the truck is used on road or is a daily driver, I would definitely replace those tires. If it was a farm only truck you could use them a little longer if you needed to but even then I would replace them. Your safety and life depend on those tires!
Rubber gets hard as it ages and gets less grippy over time.
A fresh set of rubber will give you much more traction.
Those are aged and just looking for trouble. If I am correct, tires come with an A,B,C rating for traction. I forget which way the rating goes but the softer the tread the better the traction. I had some hard rated rubber and they were dangerous on wet pavement. Harder tread is longer tread life but no traction. Softer tread is great traction and shorter life.
