Easy to install. About 5 minutes per hoop if you know what you're doing. Perfect fit for 225 75 15 tires on Ford Ranger. Be sure to use the separately available rubber tensioners. That's what the new instructions say. Ignore the reviewer who showed a photo of directions with instructions not to use them. These cables are just what you need in an emergency when you're at work and it's snowed all day and they've stood up to the plowing of the streets. I have a 35 mile commute with hills and they got me through when I was fine the previous time until I had to stop where I couldn't move due to snow and ice. There are no problems with these cables. They drive much better than thick chains. You can easily get 30-40 or so on snowy roads with intermittent unpaved sections. As stated in previous reviews. They will rustle a little after first use. But it doesn't affect their work.
