CooperTire.com once introduced the product line: “AT3 4S comes with strong traction adaptive technology – grips firmly on the road, rocky or smooth surfaces in any case“. At the 4S version, you will enjoy using a machined tire with the exclusive Adaptive – Traction technology.
Is Cooper Discoverer AT3 4S a winter tire?
The Cooper Discoverer AT3 4S is an all-terrain tire designed for on road and light duty off road driving. It’s one of several all-terrain tires to have a winter tire designation for meeting a snow traction requirement.
How many ply is the Cooper AT3 4S?
The internal construction of the Discoverer AT34Sconsists of a durable, two-ply polyester casing. A single-ply, nylon reinforcement above two high-strength steel belts further increases durability and handling response, along with providing high-speed stability.
Are Cooper Discoverer AT3 tires noisy?
It is noticeable, not overbearing or loud. I’m willing to take a little road noise for an all terrain tire that is mud/snow rated.

How often should you rotate Cooper AT3 tires?
When to rotate your tires. Most people should think about rotating their tires every 6,000-8,000 miles.
Are Cooper Discoverer AT3 good in snow?
The Discoverer AT3 has proven very capable in the snow. I’ve driven on snowy, icy roads about a dozen times so far this winter. In deep snow, and even hardpacked snow, the truck grips the ground well. Things get a little trickier on ice, but for an all-season tire, it still inspires good confidence.
Why are my Cooper tires so loud?
This happens when there is uneven tread wear. When you rotate the tires, the part of the tread with more rubber will create friction with the road surface, creating the loud noise. Not enough air in tires.
Why do my tires make a loud humming noise?
When the wheel bearing in your tires is damaged or deteriorating, it produces a soft humming sound or grinding noise when you change lanes. It’s best to have the wheel bearings replaced as soon as possible to prevent excessive damage and collisions.
Do all terrain tires make more noise?
Noise. The tires are noisier than regular all-season tires due to the tread design. Mud, off-road, and all-terrain tires have block tread patterns that make a louder noise.
Is it normal for new tires to be noisy?
New tires may produce a different (or more) noise than the previous tires due to different tread patterns and tire compounds. Brand-new tires also may need a few miles to “break in.” The wider the tire, the larger the tire’s contact patch on the road, which can increase the road noise.
How long does it take for new tires to break in?
In general, it can take around 500 miles to fully break in a new set of tires until it will offer optimal performance, so we recommend accelerating a little easier, avoiding hard braking and taking turns a little slower than usual.
How can I make my noisy tires quieter?
To reduce tire noise, drive at slower speeds and keep tires fully inflated to the recommended air pressure for a quieter ride. Tires will stay quieter longer with simple maintenance that promotes even treadwear: regular rotations, rebalancing and alignments.
How to tell the difference between tire noise and wheel bearing noise?
To confirm it, change the speed of the vehicle. If the noise becomes worse the faster you drive, then it’s almost certainly a bad wheel bearing. If the noise remains the same, then the issue may be the tires instead.
What are the symptoms of wheel bearings going out?
What are the symptoms of bad wheel bearings
- Noise: A humming, rumbling or growling noise that increases with acceleration or as the vehicle turns.
- Looseness, excessive play in the steering wheel (vague steering);
- Steering wheel vibration which changes with the vehicle speed or as the vehicle turns;
- ABS malfunctioning.
Does wheel bearing noise go away?
The classic symptom of a bad wheel bearing is typically a cyclic chirping, squealing or growling noise that changes in proportion to vehicle speed. The sound may disappear at some speeds or only occur at certain speeds. The noise may get worse when turning, or it may disappear momentarily.
How do you check wheel bearings while driving?
You can test this by gently swaying your car while driving slowly. If the noise lessens when you sway right, then the damaged bearing is likely on a left wheel bearing. If it lessens when you sway left, a right wheel bearing is likely broken.
What noise does a worn wheel bearing make?
The classic sounds of a bad wheel bearing are cyclic chirping, squealing and/or growling noise. You can also tell that the sound is related to wheel bearings if it changes in proportion to vehicle speed. The sound can get worse with every turn, or it can disappear momentarily.
How long will a humming wheel bearing last?
To determine how long do wheel bearings last is tough as we mentioned before other factors can play a huge part in determining their durability. However, a wheel bearing can last an average of anywhere from 136,000 to 160,000 km which is about 85,000 to 100,000 miles.
