FS: Kumho Z rated 245x45x17

[stephen newberg]

Well, I have put about 100km on them and decided I do not like them. Our roads are very uneven and broken up, and they just are not designed for it, so I am going to go back to Bridgestone Potenzas. Which means I have 4 of these with just about no use on them for anyone that wants to pick them up. Make me an offer. buyer pays shipping, which is about $40 per tire to the Eastern US and a bit more further away.

Thanks
Stephen

how much? and how far from Maine are you

Hi Kirk,

I am just up in Nova Scotia, so I am a very short distance from you if you are in Maine. If you are in no rush for them, you could pick them up on a summer trip and save shipping.

Price. Well, how about $85 US each? Shipping extra, obviously, if you want them sent down.

Best
Stephen

Now I'm thinking I might keep them after all. Yesterday I took off to town and the first thing I noticed was that the tires were not doing the same things on the broken sections as the day before. So I drove around enogh to be sure it was not just me, and then went in to talk to my favorite tire guy. He looked at the tires a while and asked what pressures I was running these days. I told him same as always, 36 front, 32 rear. He said something like, well, pretty cool today compared to the last week, and smiled.

Damn. The compound in these lower cost tires is apparently much more subject to temp changes. So, as a solution to overcome the softer rubber he told me to try running the pressures up a good deal to keep the overall tire stiffer. He said that a lot of these lower cost performance tires really need to be run at near the max tire pressures in the front at least, just to keep them from squirming. So, I am trying 40f/36r and latter today it is supposed to get pretty warm and sunny again, so we will see if that works. They are rated for up to 44psi, so I can crank them up more if needed.

But just in case, I still have 4 new Bridgestone Potenzas on order and I will just toss them into the garage as backup.

Have any of you had this sort of thing happen with lower cost high performance tires?

I run 44 front and 38 in the rear on my Kumhos 245/45/16s with a 26 mm rear bar and a 24 mm front. Solid AL subframe bushings and rear subframe connectors.

The Kumhos are a little weird on concrete and they like to travel the ruts.

Thanks. It is useful to hear others are having a similar feel from the tire. The higher pressure I am at now (40f/35r) certainly seems to have made a major difference. And I had them out in a serious downpour on the highway yesterday and they were not all that bad. We have been running daytime temps of around 14C (60F) here for a bit. At this point I have pretty much decided to keep them on and see what happens. As it warms up a bit more later in the summer I will likely try going up to the kind of pressures you are running.

Are you wearing evenly at that high a pressure, or is it taking off the center first?

It looks to me that the edges are wearing out first Must be all the suspension testing..

Personally i will go with a narrower tire next time. 235/50/16 of some sort.

The Kumhos are not very good below 32F

I have already purchased some Bridgestone Potenzas that will replace the Kumhos for spring/summer/fall use, in 235x45x17, so they will be here and ready just in case these are not up to ***** for the hotter weather during high summer. And if not needed, I will put them on for next year's use. Though they seem ok with the higher pressures, they are still nothing to write home about, IMO. I only have them since they came without additional cost along with the 17" rims I wanted. I certainly would not buy them otherwise, from this sample.
