Does anyone else notice a little rough riding for the first 1/2 mile or so after the car has sat overnight or the weekend?

My thoughts are that the tires develop a flat spot or due to the stiffness of the sidewalls on the LX tire, sitting overnight or for the weekend causes them to become slightly out of round and it takes a bit for them to get back to their round state. Does this sound reasonable?

I have the LX and my tire pressure is set a 30 lbs on each tire. It only happens first thing in the morning, not on subsequent trips in the same day.

Yes! And it bugs the crap outta me. It's worse in the winter when it's cold, too - I think the tires stick with being out of round much longer.
I don't know if it's a problem with the tires themselves, or the wheel design.

When did you get your Sonata, zrago? I see that you're from Illinois - if you didn't have it on cold days in the wintertime, be prepared for some more of that out-of-round feeling, but having it last much much longer than 1/2 mile.

Mine does it even during the daytime, when I leave it parked at work. Now, since the weather is warmer, it goes away pretty quickly. I LOVE SUMMERTIME!!!

:clap:

Pretty much any car I've had with Z-rated tires has done this, including the Hyundai. I think it has something to do with nylon in the rubber mix.

Good to know! So it doesn't matter what brand of tire you buy when the time comes to replace them? I'm nearing 30000 miles and quite interested in everybody's opinions here as to which replacement tires I should buy.

I bought it in late February. The weather has been pretty mild overall, plus I park it my garage.

I guess I'll just have to deal with it until these tires wear and then shop for a set of replacement tires that are resistant to this condition.

i get the feeling you guys are just oversensitive...
are any of you attracted to the same sex..... :innocent:

30,000 ? Our car will be a year old next month and we're just a tick over 7,000. :grin:

Holy crap dude...when did you buy your car? I bought my Tuscon in Nov 04 and managed to rack 32k before i traded it in last month......how much do you drive?

Now that you mention it, I have always found your posting style incredibly sexy. Don't worry, though, I'm a big, manly, discreet 6'6" 300 lb. teddy bear that just needs a little beeyotch for some good times. Whaddya doing later, honey?

:wink2:

(sarcasm in case anyone took it too seriously)

To answer everybody's questions about my mileage...(you must not read the mileage thread, I thought I'd bored everybody to tears with tales of my commute)...I travel 250 total miles a day and picked up my Sonata in mid-November 2005. I've got just under 27000 miles on the dial.

And no, I'm not interested in any "alternative lifestyle" type stuff (in case you're still blinking after my last post), I just wanted to mess with willay's mind a bit.

mc229, recently I replaced the tires on my ford taurus with Kumho tires. I've had Generals,Michelins and Bridgestones on this auto and I can tell you that there is no comparison to the ride the Kumho's provide.Again Korean technology! :clap:
I did alot of research before buying this brand and was afraid I would be sorry for making the purchase considering the price compared to other brands.I had four of their latest tire for the ford (Solus KH16) mounted by a local tire dealer for $207 out the door,that was half of what I could get the Bridgestones that were being replaced and that didn't include mounting.
When it comes time to replace the Sonata Michelins I will be replacing with Kumho.
Found 2 recommended Kumho tires for the LX at www.tirerack.com
1.Ecsta ASX $88 each / 2. Ecsta KH11 $108 each
Check with a local Kumho dealer in your area,you may get a better deal including mounting.You can also get more info at Kumho Tire's web site.
:thumbsup:

Thanks for the info! How many miles are the Kumhos supposed to last? In other words, are they a "softer," less durable rubber?

The Michelins are only supposed to last 30k miles according to my dealer, but my tread seems pretty thick to me (they were amazed how thick it was when I had it in for the 22,500 mile service). I'm really good to my car, though, don't race it, don't peel out, and only cruise at 55 mph on the highway lately. Before I would occasionally take it up to a triple-digit jaunt, but that was only for a half-mile or so every now and then and didn't peel out in the tires. I'm hoping for more than 30,000 miles before I have to change them, in other words.

The same 30,000,the lower profile sport tires are mfg with a softer rubber so they don't last as long as regular passenger tires so we get to purchase them about twice as fast. :crying:

You guys are making me laugh so hard I'm going to wake everyone up! :w00t:

About the rough tires: I have noticed that all tires ride rougher on cold mornings.

I'm quite happy with the stock Kumho tires the Sonata comes with here, especially for daily commuting in mild weather, but in the rain, they seem very unsure of their orientation (no pun intended, mc229). I think I'd like to try some Yokohamas when I put on new rims. Has anyone tried the Advan S4?
