Tough and Long-Lasting Toy for Heavy Chewers
Size: Large, Product Packaging: Standard Packaging
The KONG Extreme Tires are built for dogs who chew through just about everything else. Made from KONG’s most durable rubber, the toy is designed to stand up to strong jaws while also offering a fun shape that dogs enjoy rolling, chasing, and chewing. The tire design has grooves that can be stuffed with treats or peanut butter, which helps keep dogs engaged for longer play sessions.
This toy is especially useful for large breeds or heavy chewers who usually destroy softer toys in minutes. While no toy is completely indestructible, the Extreme Tires hold up far better than most and provide both chewing satisfaction and mental stimulation. The size is hefty and best suited for medium to large dogs, and smaller breeds may find it too heavy.
Pros: The rubber is extra durable, the tire shape adds variety and fun, and the grooves can be filled with treats for extra engagement.
Cons: It may be too heavy for smaller dogs, strong chewers can still wear it down over time, and it isn’t designed to bounce or fly like other KONG toys.
A rugged and reliable toy made for power chewers. The Extreme Tires provide long-lasting fun and double as a great option for treat-stuffing, making it one of KONG’s toughest and most useful toys.

Well-made and great size for the price!
Color: blue black
Very tough product, no odor of plastic, good toy for outside, perfect for medium or large dogs. Noise isn't too bad and the color is cute as well. Can't destroy this toy!

Durable Great for aggressive chewers
Color: Blue
Will make one whole room smell like fake bacon, but my dogs love it and it’s super strong and durable. I have a lab mixed with rotty and a full lab so it’s a perfect match.

Durable, Dogs love it
Color: Red
My Frenchie is a crazy chewer and can chew up a nylabone in a day, so I was looking for something that would last longer. So far this is holding up, and is pretty durable. Both my dogs like it a lot, it’s easy for them to grasp, and chewable but still very tough material. I suspect at some point it’ll wear down, but not for a while. The size was just as described / expected. Not too small and not too big
