TPS still works fine with non-run-flats.

If you get a flat with non-run-flats, you have options. You can sit on the side of the road, keep driving on it, make a call, or try a roadside repair. I carry a can of fix-a-flat, a puncture repair kit and a compressor in the back of the car for that purpose. The fix-a-flat might stuff your pressure sensor if used, but those things are only $100 each.

 

By the same token, why not buy Pep Boys brake pads, Gabriel shocks, Kmart wax, and ebay steel wheels? C'mon, we're talking about a car that costs $50,000 new. Let's not treat it as if it is a Kia that cost $8,000 new.

 

I had Kumhos on my old Vette and was not happy with them. They offered acceptable levels of grip. They worked OK at the auto-x and gave me 1.9 60fts at the drag strip.

But on the street they killed the car for me. The steering feel was very vague. Front end just felt very mushy on turn-in. The car also felt floaty and less secure at highway speeds and above. My alignment was dead on and I played with tire pressures quite a bit. I could never get a setup I liked with these tires. These were stock Z06 sizes (except for 275 in front) on Z06 OEM rims.

I switched to more expensive PS2s and wish I spent the extra money in the first place. I also found the OEM Goodyear Supercars to be much better than the Kumhos as well.

 

I ordered a pair for the rear today. I drive my car daily, I am sure they will be fine. They are not the cheapest tire for our car, and the ratings from discount tire are pretty good. We shall see.

 

I've had ASX's on mine for a while. The grip is not as great as I'd like, but they aren't supposed to be. I was using it as a DD for a while. The next time around, I'll either get Michelin Pilots's or Kumho's. I don't like the road noise of the EMT's. Sounds like a tank.

Being non-runflats, they do handle a little differently.

 

Pick any tire and you can likely find someone delighted with it, and someone disgusted with it...

Well, except these beauties maybe:

First time I've seen these, don't all rush out and buy them at once.

 

I read that whole thing, even they admitted it was real close.

And IMO tires are one of the only things where "You get what you pay for" doesn't matter.

But hey what do I know, in the years of the family owned tire store you know what 2 brands I saw more shifted belts in?
Goodyear and Michelin.

Why are they so expensive? Well it was said before.
Advertising and labor cost.

Kuhmo makes a great tire. I've run the MXs many many times on the road course with just as good or better lap times than the BFGs or the Goodyears I had before.

 

On friday I got new Z06 wheels and Z06 sized Kumho mx's (front 275/40). The ride is much softer, no bumpsteer, and traction is much better than the runflats.
BUT, they feel like sponges, turn in is soft and on sharp cornering they feel like they are gonna fold under the rims
That part pisses me off. I like to run my car hard and it does not inspire any kind of confidence. I think I should have gone with 35 and 30 series instead. The tires seem kinda tall too. Im running 31 psi front and back, cold.
PS, treadwear is 220 and the sidewall flex feels like 5 times more than the runflats.

 

the key word quiet and affordable.I'll give em a try when it's time. tire rack under $500.00, plus 43 shipping

 

Just ordered from Tire Rack Khumo Run Flats. $866 shipped. Getting them installed 3/22. Will let you know. I won't miss my GY. I also am not at agressive driver. Got 31,000 on GY.

 

In my opinion, Kumho do a good tire at a great price.
Like been said before, for daily drivers, these tires are excellent.
Sure, if you want to do racing in the rain / damp, well. . . . .
So, where every buck counts, it is kumho's for me.
They all wear away eventually any how,
Oh, and good mileage also.

 

I will post my results Tues. Having the Kumhos mounted

 

I called the Tirerack on three different occasions over the years (keep in mind that they do their own tire-testing and know first hand how well the tires they sell, perform.) and each time I asked how the Goodyear GSD3s compared to the Khumos, I was told, "The Goodyears are definitely superior."

It doesn't take a rocket scientist to realize that there must be some truth to that statement, having been told more than once by different Tirerack reps, but as more than a couple of people have stated here, these are not in the same league as the D3s and PS2s. As long as you realize that when you buy, you may not be dissappointed.

BTW, here is an early tire test that compared the GSD3s to some of the better tires (at the time):

"Productreview: F1 GS D3
By Dan Barnes
Photography: Dan Barnes

Designed in Europe, the Eagle F1 GS D3 is Goodyear's "first truly global product," and its first tire aimed at the maximum-performance tire segment. The Eagle F1 GS D3 targets sport compact and tuner vehicles, and follows Goodyear's traditional emphases of maximum wet performance and good, all-around driveability. Goodyear is producing the Eagle F1 GS D3 in 39 sizes, from 15 to 21 inches.
The Eagle F1 GS D3 has internal construction features expected from the latest maximum-performance tire, including high-tensile steel belts, spiral-wound cap plies for excellent roundness and high-speed durability, high ply turn-up for strong sidewalls and quick response, and a rim flange protector molded into the sidewall.

It's the tread design that sets the new Eagle apart. It's divided into three zones; a solid center rib for good steering response is connected to shoulders with large, solid tread blocks by a series of power transfer bridges. The latter are part of what Goodyear calls V-TRED. The diagonal grooves are three times the length of the contact patch, helping evacuate water and avoid trapping air, thus reducing noise. Goodyear refers to the tread compound by the AAtrax moniker, emphasizing the tire's AA UTQG traction rating.
We sampled the Eagle F1 GS D3 at Goodyear's proving grounds outside San Angelo, Texas. The 7,250-acre facility has 58 miles of roadway with 53 different surfaces. There we witnessed demonstrations of wet-traction testing with a pickup truck and trailer test rig, as well as the phosphorescent hydroplaning test made famous in Aquatred commercials. The latter can be done at speeds approaching 200 mph for racing applications. We also drove the new Eagle F1 on a dry-handling loop in 2002 Audi A4 sedans. At moderate to high slip angles, the Eagle F1 felt like a good, ultra-high-performance tire, but it does make more noise than most tires in the maximum-performance category when cornering loads rise. The grip-slip knee in the load/slip-angle curve was very gradual. That made the tire extremely forgiving, but it also made it difficult to decide how hard the tire wanted to be pushed for best speed. Overall, though, the strongest impression was that the Eagle F1's capabilities were well beyond those of the stock Audi's suspension, and a complete evaluation would require a car with more aggressively tuned dynamics.
For evaluation on its Vehicle Dynamics Area, flooded to 0.050 inch with water, Goodyear provided three convertible Corvettes equipped with automatic transmissions. One Vette wore Goodyear Eagle F1 GS D3, one wore Michelin Pilot Sport and one Bridgestone Potenza S-03 tires. Though the cars were theoretically identical, they were rentals and could have had some differences.
In a braking test, the numbers indicated the Michelin third, Bridgestone second and Goodyear first, inverse of the order in which we drove them. Interestingly, we didn't feel the ABS pulsing for the last third of the stopping distance with the Goodyear.
On the wet autocross, journalists were firmly instructed to drive in second gear with the Traction Control System on line. The Goodyear worked well and showed a gradual, forgiving nature. The tire was also well matched to the Corvette's TCS, which intervenes very late, and allows the driver to get sideways. The Michelins slid more and sooner than the Goodyears, and the car was a bit tail-happier. The Bridgestones slid the most."

 

some pics too please. I want to check out the profile on them

 

I've had 2 sets of kumho asx's. One set on thin spoke c5 rims which have been balanced 2x times with a hunter machine. With a lot of weight they are close but still have a consistent non-solid feeling about them. The other set was on an o6 mini cooper s which was balanced 3x times using a hunter machine. These tires flat out vibrate...I believe a tire is out of round. At present I've got one set of michelin's Exalto's on after market mini rims with less than 1oz of weight per tire and are spot on. My brother was a tire tech until he got his ase mechanics rating and swears by michelins. I've also had 3 sets of GY d3's, 2 on the vette and one set on the mini which all balanced up well and handle arguably the best but I found a bit stiff walled and noisy, there's always a compromse. I've decided to bite the bullet and buy ps2's for the vette, can you guess why?

 

I will do it man

 

I love Kumhos

 

Don't forget no bull **** OSHA rules,
no workman's comp,
no employee lawsuits...


BTW, I love my Kumho Ecsta MXs

 

Rather than reading Kuhmo bashing from those that went out and spent big bucks for other tires...I'd like to see comments from those that actually run Kuhmo's now. And how they feel the Kuhmo's stack up to their previous tires..Best people to have a take on Kuhmo's are the people who have them!!!

 

I have them on my everyday driver great tires and very reasonable priced
