Kumho Solus KR21 Review & Rating Rating

Product Overview

  • Dry, wet and winter traction
  • Steering response
  • Ride comfort
  • Road noise at higher speeds
Bottom Line: 4 / 5

Created for year round all-season use at a budget-friendly price, the Kumho Solus KR21 aims to offer a smooth and quiet riding experience coupled with good traction and grip.

As a way of appealing to all sections of the market, the tires can be used on coupes, family sedans, SUV’s, minivans and pretty much any vehicle that they will fit on. This is all well and good from a marketing point of view, however, how do they shape up when put to the test on the road?


Traction is one of the selling points for the Kumho Solus KR21’s and as an all-round tire they offer good performance.

The tires come with an advanced carbon tread compound that ensures that they grip and hold well on both dry and wet surfaces. While they may not perform quite as well as some of the higher priced tires on the market like the Michelin Defender or Hankook Optimo H727, for their price the KR21’s are a lot better than some of the offerings currently available. Overall we had no real qualms with the traction and grip this tire provides, so it gets plus points in this category.

Cornering – Steering

We found that the steering on the KR21’s was actually very good. They provide comfortable and easy steering and it never felt too light or heavy.

The tires also feature a continuous center rib that quickens steering response and also allows for better cornering stability. Although you won’t mistake this tire for a high performance model, cornering grip and stability are both very good.

Winter Handling

While the Kumho Solus KR21’s claim to have all-season performance we have found that, with most tires, this is never usually true. So, how did they fare?

Actually, for a fairly low priced tire that is supposed to offer good performance in all conditions, they weren’t bad. They use cross-groove shoulders and full-depth sipes to improve their grip and traction on snow covered road surfaces. Generally speaking, you can expect better than average traction in up to 6 inches of snow. Driving on ice sees adequate traction, but keep in mind that these are not winter tires.

Ride Comfort – Road Noise

An area where we felt, as have many other drivers, that the Kumho Solus KR21’s let themselves down somewhat. Comfort wise they are very good and certainly better than many tires in their budget range. That being said, they have a few issues with road noise. The tires come with notched intermediate ribs and also a continuous center rib that is around the tread; theoretically they should eliminate road noise altogether, however at around 70mph the noise did pick up. They aren’t the noisiest tires you’ll find, however there was a slight drone at higher speeds. This may or may not be a big deal, but an issue you should be aware of.

Tread Life

Kumho Solus KR21Generally when it comes to budget range tires there is a shortage of models that have good tread life. The higher you pay the more value you will get out of them is the usual experience, however, the Kumho KR21’s actually have reasonable tread life for their price.

While many have commented that they fall short of their warranty (see below), in our experience the tires perform adequately. You may not see a high level of treadlife from the K21’s, but the advanced carbon tread compound will help to extend their usage beyond a normal budget range tire capability.


The KR21 has an 85,000 mile warranty which is really good for their category. Even though you may not get this amount of mileage from them, this is one of the better warranties around. They also come with a 72 months workmanship warranty as well.
