Kumho has recommended these tires for my 91 for my everyday driver up north here. We had snow last week for a few minutes!
Looking for a softer ride than my dunlop sport 9000's.
Any feed back from those cushy ride allseason drivers!

This is what I said:
I have currently bought a 1991 Acura Nsx in excellent shape with 126,000 km on it. Everything is original It currently has the DunlopSport SP9000 Tyres on the stock 15" & 16" rims. I have read many posts on forums regarding which current tyre is correct for this car. Everyone agrees to disagree. The origianal Yokos where corner specific tyres. Each of the four Tyres where differnet. I using the car as an everyday driver to work and to play. I would rather have a bit softer-smoother ride than some track hi-performance tyre would give. I'm looking to cruise the streets. I have currently dropped my air pressure to 32 front and 35 rear to smooth out the ride. Edmonton streets are the shits and the car likes to grab the grooves made by large trucks. The alignment seems to have been done a year ago and the toe out is very small compared to the 91 spec, ( this is a good thing). Let me know what you might want me to try for a tyre. You may use my car as a test dummy if you need one.

This is what he said:
he only model that we have to fit your application would or ECSTA MX. It is our best performing high performance tire. The MX will handle better than your Dunlop's, but ride comfort would be about the same. Later this year we offer our ASX all-season tire in the sizes you are looking for, but the front size will not be available until September. The ASX will offer you a softer ride at the sacrifice of some of the handling of a Dunlop sport or our MX.

Last week good buddie Eddie lent me his spare rims and tyres.
The car runs great on the road but corning is not the best. Doesnt't grab any cracks or grooves. Must be something up with the Dunlop 900's. Borrowed Set up is Toyo Proxes FZ4 on the Front and Nice Yoko AVS 1S-Z on the rear. Thanks goes out to Eddie for lending me these tires. I was going crazy with the Dunlops.

I don't think it makes sense to use all season tires on the NSX, especially in Canada. If you drive your car when it snows, you would be much better off getting an extra set of wheels for a set of true winter tires, and using high-performance tires ("summer tires") the rest of the year.

There is a wide variety of tires that you could use on the NSX. I think the claim that these two Kumho tires are the only ones that fit is poor advice and just plain wrong (although it's natural that they wouldn't mention all the good tires made by other manufacturers). I suggest you check with a good tire retailer that carries a lot of different brands, such as the Tire Rack. Two Canadian-based tire retailers are 1010tires and Talon Tire.

However, it's also worth mentioning that perhaps the problem is not the tires; if you're looking for ride comfort, perhaps a high-performance sports car like the NSX is not your best choice...
 
I forgot to mention!

I forgot to mention, everyone can reply except for nsxtasy!!!

Picture of Toyo Allseason

Here is a pic of the V-rated Allseason tire buddy boy lent me to try. The car drives true and straight now and doesn't pull from side to side in the ruts. The ride is nice and soft on the terrible roads here! Of course I need two lanes to make a turn compared to the Dunlops but thats the price you pay to turn your nsx into a cadillac. They really aren't that bad, we had them up to 100 mph with no problem at all. Smooth and quiet. I will be talking to Dunlop shortly to see what they think might be the problem with the sp9000's. Also as nsxtasy suggests, i should get the car fixed for any worn steering parts, ie: tierod ends, bushing....
Thanks to all.

mix and match tires are a big no no on nsx.. but of course there's exception and you might need a lot of testing to find a good "match".

I used Kumho MX on my X and I loved 'em... Seat on the pants by my intructor's at my last DE was that it grips better than my cousin's Bridgestone S03's.

Yes, real snow tires for the white stuff; and you should be fine driving the MX around all year. I drove it once even on fresh sludge (it's not sticking though) and I got home ok...

Hope this help.
 
ffffanman --> those rims look soooooo clean....
