Now that more time has passed, I'd like to bring up this subject again. Those who have been using Kumho Solus KR-21 please chime in.
Mention which vehicle you are using these tires on and how many miles there are on the tires. Are they staying in balance, still quiet?, ride/handling combo, traction wet/snow/ice/dry. Mention anything that comes to mine such as tread life as compared to the mileage warranty.

Those whom I have recomended these tires to are all still pleased. ATMOF, nothing to report. The tires go about their business without issue. Very unnoticeable, which is a good thin! Also, these friends/family using the KR-21's don't drive hard, just normal everyday driving. Some drive a little harder than others or course but, not to say hard driving(fast cornering/hard exceleration). These folks have a combo of SUVs, Mini-Vans, Sedans.

I want to put the KR-21's on my daughter's Mazda3(205-55-16) to replace the noisy Dunlop Signature. This Mazda has sporty/zippy w/good handling but,she doesn't drive hard, just alot!

Thanks
CB
 
I used up a set a V700's I used for track days and they were excellent high performance tires.

I Bought a car with a set of street Kumhos and all 4 had belt separations with low miles.

I sure improvements have been made since then.

Do a search take a look at tire recalls before you settle on a street tire. Kumhos have had problems.
 
I have these on both my Civic and CR-V. I'm on my second set on the Civic. First set lasted about 70k, but after about 55k one had severe run-out. Otherwise, they are absolutely money in the snow and rain at highway speeds.

A friend on a minivan forum I'm on had the KR-21s on a FWD Oldsmobile, and he reported the same thing (slipped belts in multiple tires). He ended up replacing all four with a different brand. As of this point, the Kumho brand is too hit-and-miss for me to buy them. I have no doubt that their objective performance is good, and that some of the tires are very good quality. But there are too many reports of unhappiness or tire failure for me to buy them, for now.
 
OP, consider the Pirelli P4s instead of the Kuhmos. After researching quite a bit, and after reading Bill's thread about putting them on his Corolla, I have ordered a set of the P4s for the wife's Corolla.

I did put a set of the Kuhmos on our old Citation a few weeks ago, so far so good. But I want better tires for the Corolla, so I'm going with the Pirellis.

Here is Bill's thread about his tires...

I replaced those Kumhos with Fuzion HRI and that may have been the best bang for the buck I ever spent on tires.

I have the P4's on my Altima 2.5S and I like em very much but their a little hard riding but quiet.

Take a look at Kumho eco Solus HM KR22, it seems to last a long time and "extremely low tire noise and highway comfort" as someone said on Tirerack.

These are good quiet and soft ride tires: Yokohama Avid TRZ and Yokohama Avid Touring-S

All these tires are about $90 or less at Tirerack.
 
I had the KR21's on 94 NISSAN Path Finder , and two sets on my Toyota Celica. I liked them alot and felt safe with them on especially in the snow, and I lived in the snow belt near Erie , PA with the lake effect snow day in day out. The Toyota ( front w d ) went like a tank with them on. I got about 40 k on the first 4 tires......went and bought 4 more of the same.
The NISSAN Path Finder had them on too , but being a high profile truck and a light a$$ end , I prefered to use the Toyota in the snow / ice / or rain.
SSOOOoooo in total I had 12 KR21's , never a problem with any of them.
Fast foward.....I picked up a 2005 Camry and I put Yokohamas TRZ's on it just for a change.......betcha the KR12'S would have been the better choice.

Pretty much the same for me too at the moment. I've seen them do well, but I've also seen two fail on a saturn vue....
 
Just like oil, the newest formula usually better than the old. in buying tires, I usually looking for latest designs. They are usually better in every ways, better ride, better performance and lower rolling resistance too.

Kumho KR22 is a new design so that not many reviews to look at, but at around $90/ea and UTQG at 800 A A it is hard to beat.
 
I have had a set on a 93 geo metro for 2 years about 10,000 miles. They are great in snow! Show little wear. There is some very minor weather checking on 2 of them, but otherwise I am happy.
 
I am on my second set on my Intrepid. The first set lasted 40,000 miles. Discount tire pro rated the warranty for a second set. On most vehicles I would say they should advertise a 50,000 mile warranty. It would be much more accurate and honest. Besides them wearing out they were a good performing tire.

Yes, I have looked into the Yoko's and they too are a consideration as were the Pirelli P4's. I have the P4's on my 04 Altima and I like em very much but Im really wanting to try the KR-21's/ or maybe the 22's. When were ready, and there is more data/reviews from thetirerack, we may get the KR-22's, we'll have to see! Need good snow traction as my daughter drives alot in the Buffalo/Niagra Falls area as part of her job. She said that the Dunlop Signature(as I mentioned earlier), did very well this past winter but are noisy.

The Pirelli P4's can be a bit on the harsh side when traveling over expansion joints on the highway. Summer time their better while also lowering the PSI (2-lb's under the recomendation) in the rear tires. Nothing is in the rear for weight except a tank of gas anyway!

Well, for an 80,000 mile tire, this isn't good. I'd take 60,000 though! I got 60,000 out of my 60,000 mile warranty'd Good/Year Integrity's(garbage) and could have still gone 5-7000 miles more but I hated them.

Same with the Avid TRZs in my experience. They seem to harden up in the colder months. Could be the struts on the car also. The Michelins on our minivan are consistent no matter the temperature. To me, this is one of those "intangibles" you get when you buy $100 tires instead of $70 tires. To some people, it doesn't matter. I get annoyed with the TRZs enough to swap them out in the winter, then when summer comes, I'm loving the grip and the ride smooths out pretty good.
 
I had KR-21's on my 98 Volvo S70. I do mostly highway driving. They had great traction and were quiet. Unfortunately they only lasted 37K before I was close to the wear bars and replaced them. I also had to rebalance them twice in that time. I recommended them initially to a friend on their 2002 Jetta and they have had nearly the same experience. I won't buy them again. I am running Pirelli P4's now...so far so good, but I only have 3K on them.

I am considering Cooper CS4's for my other car soon.

OEM Korean tires are garbage.

If you want good Korean tires, you have to buy Non-OEM kinds.
 
The P4's look great. The Fuzion tire made by Bridgestone/Firestone are a "H" rated all season tire not a performance tire.

Well, I'll look into them a little further but, I'll still probably get something else. We'd like to stay with "T" rated tires. Maybe our choice won't be the Kumho's either. I want something that's rated for 80,000 miles and I'll take 60,000 out of it. I've thought long and hard about the AVID TRZ's til I discovered the Kumho KR-21's.

The funny thing is, Im doing all this talking and I just may end up with Michelin's...I just hate paying their money.
