Cooper Discoverer STT Pro Tread Life

Cooper Discoverer STT Pro Tread Life

While all highway tires these days come with a mileage guarantee from the manufacturer, many off-road tires generally do not.

There are some exceptions to this rule, but the Cooper Discoverer STT Pro is not one of them. As a result, it can be hard to know just how long these tires will last. And of course, how long they last depends on how you use them, the amount of off-roading you do, the types of surfaces you off-road on and, critically, if you rotate them properly.

While generally tires that fit in the same competitive set as the Discoverer STT Pro get around 30,000 to 40,000 miles if you’re lucky, we’d say that number is more accurate here for those with extreme off-road use.

Surveying owners online it’s not hard to find those with more than 40,000 miles who are reporting significant tread life left. Based on that data, we’d expect 50,000 miles is likely for moderate off-road use.

When you are on-road, one of the real surprises of this tire is how it behaves over time. A reasonably quiet tire (for a mud terrain tire) we’re impressed by how it doesn’t get louder after the first few thousand miles – something we’ve come to expect with tires in this category. Surprises like that are always appreciated!

How to Rotate Your Tires

If you’re looking for some advice on how to rotate your tires to ensure maximum tread life, here’s a helpful and humorous video that helps. The criss-cross method is the simplest one and it works for almost all models. Essentially you swap the front left tire for the rear right. And then swap the front right with the rear left. You’ll want to do this every 5,000 to 8,000 miles.

It’s important to note, however, that this rule doesn’t apply to directional tires (tires that are designed to only operate in one direction) or staggered fitments.
