Kumho Solus KR21

[elliotgb]

I'm finding that my Kumhos are happiest when the psi is set to 34lbs per tire/cold. I had them at 32 and the handling didn't seem good. When they heat up they get to around 36-37 lbs and the handling is much better.
Still having the wind problem but haven't had time to get back to the tire place to check the front end.

My understanding is that the manufacturer's recommended tire inflation for these tires is 41-44 psi, depending on your load. That's probably why the dealership is inflating to 40 psi.

I don't think I'd run them so low as you risk improper tire wear and, in warm areas of the country, the risk of tread delamination (Explorer/Bridgestone problem) due to heat build-up. Also, the low inflation will have a negative impact on your gas mileage.

What are you using as a guide for the tire manufacturer's recommended inflation? The markings on the tire itself are never the recommended inflation, just the MAXIMUM safe cold inflation. That number should never be used unless you are loading the tires to their maximum weight capacity.

I just purchased my Kumho Solus KR21 last week and LOVE them! Just for the price and the 80k miles... WOW! but then they are so quiet also! compared to the Goodyears that came with my MO! but i do have a confession, my Goodyears lasted 75k miles! pretty good! but i did wait a bit long on that! mainly because i though i had to spend $800 on new tires. i got my Kumhos for $108 each with LIFETIME rotation AND BALANCE. CANT BEAT THAT!
Thanks for all of the posts on this tire, it really helped me make my decision.

My dealership inflates my MO to 40 psi as well. I asked about the 33psi and they said the tires will wear better at 40 but make a little more noise. It's about time for "new shoes" at 36k mi and after reading the positive experience with Kumho for MO as well as many other autos, I'll be going with KR21's.

When I have the chance to test snow performance, and I will, I'll post my opinion.

IMHO:
The "Best" ands down tires for the MO (or almost anything else for that matter) are Nokian WR. ($225/per) Like Kris says, you get what you pay for...
I don't have them BTW.
Being European mfg, the price is quite inflated due the weak dollar..

I am thinking of putting these on my wifes honda pilot. Any word how these handle in the snow?We still have not decided on if we are keeping the MO or tradeing it for the frontier. If we keep it I may end up putting these tires on the MO if they are decent in the snow.

Thanks

We have not seen a single flake of snow so far this year in the carolinas. Rain is short by some 20 inches so far. But I can tell you the KR21's are the best tires I purchased so far for any car, period!

Thanks

I am here in Cary, NC. I have about 3000 miles on my KR21's. I drive from here to Wilson and back every day. I did hit one of the few thunderstorms we had here about a month or so ago and the tires did excellent in the rain.

Took MO into my Nissan Dealership at Southern States and told the SM about my front end vibrations. I told him that it tracked straight( so I did not require an alignment) but had some disturbance when there was a lot of wind and passing semi's. He rebalanced all the tires and everthing is much smoother. Due to the cold snap the tires went down to about 31 psi and I recently pumped them up to 34 psi all around. Ride is good now,

Anyone have a picture of the Kumhos on the Murano?

I had a similar situation with the balancing. The local tire guys could not balance it at all. I had to take it to Discount Tires and get it balanced using a Roadforce balancer. It was a major improvement in the way the tires handled after balancing with the Roadforce machine. As far as the tires are concerned they have gotten significantly quieter after about 3000 miles!

Discount Tire told me that the KR21 has a less rigid sidewall than the OEM Eagle and wouldn't handle as well in turns, etc. Can anyone confirm this?

Thats a bunch of baloney.The KR21 handle fine. Better than OEM tires because they are as good as the OEM in handling but quieter and cost half the price. The discount tire guys obviously want to sell a tire package thats gonna cost you $800 (Michelin and Yokos are their preferred tires) as compared to the KR21's that cost you about $360-400.It might make a small difference if you drive like a maniac but under normal driving conditions it does not make a bit of difference. If handling is your primary concern you should be driving a BMW X5, Porsche Cayenne Turbo S or Infinity FX45 and not a Murano.

With the snowfall around the country this past week, has anyone had a chance to try the kumhos out in the snow? How do they handle?

I saw one at the dealership on an '04 MO and it looked good. I think it looks better than the GY LS on one.

Here's a link to what the tire looks like. http://www.tirerack.com/tire-12/Kumho/Solus+KR21.shtml
