Kumho Solus KR21 Tire Review & Rating

Designed to save you money on new tires, Kumho has created the Solus KR21, which combines a smooth quiet ride to go with confident all-season handling and traction. This touring all-season model is developed for all types of coupes, family sedans, minivans, SUV’s and other vehicles.

The advanced carbon tread compound on the KR21 is engineered to provide enhanced traction on dry or wet surfaces, as well as a longer overall tread life. Cross-groove shoulders increase the tread area and add “biting edges” that are designed to improve snow traction and handling in all-weather conditions.

Kumho Solus KR21 Tire Review

The tread pattern sports four circumferential grooves and deeper sipes to provide better grip and handling on wet road surfaces, while also reducing the risk of hydroplaning. The results are increased safety and added driving confidence.

Road noise is virtually eliminated through the use of notched intermediate ribs and the continuous center rib around the tread. We’ve heard from many drivers who say this is one of the most quiet tires they have driven on.

Inside the tire you will find two steel belts with nylon belt edge layers and a polyester cord body that give the KR21 more strength and stability at higher speeds. This is something generally found only in more expensive high performance tires. Kumho offers a wide range of 13-18 inch sizes, and all sizes carry an 85K mile tread warranty.


  • Dry traction and handling are above average
  • Steering response is impressive
  • Ride is very quiet and comfortable
  • Low cost offers great value


  • Some have mentioned shorter treadlife than 85,000 warranty
  • Increase in wet traction

Overall Thoughts

The KR21 is one of the lower costing all-season tires on the market today, making it a very popular choice for those looking to spend the least money possible on new tires. Beyond the cost savings though, you’ll find a tire that is a pretty good overall performer on the road as well. Traction and handling on dry pavement is very good, and cornering grip and all-around stability is on par with better models in this class. You’ll also find that the ride is quiet on the road.

Along with the positives, there are a few negatives that come with the KR21. Despite the fact that this tire sports a 640 UTQG rating, we have heard of some drivers mentioning a shorter treadlife. A few have spoken of getting only 40K miles out of the tread, which is less than half of the 85K mile warranty. To be fair though, we’ve also heard from a number of others who have spoken highly of the tread wear. The other area we would like to see improved is wet grip at higher speeds. For whatever reason it just doesn’t seem to deliver the kind of confident feel at the limits that we like to find.

Overall, for the lower price, this model offers pretty good value for the money. We also like the fact that Kumho has built a large number of sizes in smaller fitments for those who drive older vehicles.
