Road/tire noise.

they were pretty decent tires but not the best in the UHP AS category.
You've never said this before that I have read. You said that the Motivo's had a weakness (which you had "discovered") on icy roads. Now you are saying that there is a better UHP A/S tire out there? Which one?

The reason why I question this is because any A/S tire is going to underperform when compared to a summer UHP tire when the road temps are well above freezing (minimum c. 40F as stated by Michelin). The Nitto Motivo UHP A/S tire is the best compromise for year-round driving in most climates. We've all agreed that in heavy, long winter areas any A/S tire is not going to cut it; so might as well go with winter and summer tires and swap them out. I have come down on the side of A/S in winter because of our local weather (not in the canyons, mind) seldom being snow or ice on the roads; thus an A/S is the best compromise for most of our driving conditions. But an UHP A/S is going to get outperformed in the "gription" department by a softer A/S on frozen roads. Above freezing roads will swing the advantage back to the UHP A/S. So it depends on what you want to prepare for.
 
Thanks for the info. Hopefully I have time before the Pilots wear out, failure is more likely with a pothole. I’m in Los Angeles but want to be able to go to Vegas in the winter and not fear a cold weather issue. I have no need for two sets of tires like or cold weather Stinger owners, like Merlin.

You know, if you're not traveling to colder climes (Las Vegas is not a colder clime) Pilot Sport tires should be just fine. Living in S. Cali, I'd just replace worn out Michelins with the same thing, or maybe less expensive Firestone Firehawk Indy 500 (even though they are W and not Y rated).

There is no way that the road surface even in the middle of winter is going to be a traction problem for summer tires down where you live. That far south, from coast to coast, summer tires will be perfectly safe. If you happened to hit a cold snap that lasted a week, then maybe you'd want to back off a little from your "wild cornering". :D Other than that precaution, any summer tire is going to work without issues.

Going to Vegas from here I hit elevation (4000’) twice and there can be ice patches and cold, below 30* then and Vegas can also get quite cold and now with climate change 6” of snow. That was on the Summerlin side of the valley. Not quite a winter wonderland yet but...

"Climate change", heh. There is always such a thing, long before and long after humans. :P Our little existence (other than potential nuclear holocaust) doesn't "change" anything in the intermediate, much less long term. But that's more of a political agenda discussion, so I will leave it.

The facts are these: winters down where you live tend to be mild in the extreme. That means when there are moments of freezing they can't get a grip on the land. Your mountain passes in the "dead of winter" might see a frozen patch here or there, but you'd have fair warning because of the current weather. If it is precipitating, and you're going up to the passes, then of course, take it out of CC, reduce your speed, don't maneuver suddenly, and do the "tippy toe" through the pass and down the other side. Lower elevations won't be freezing. Unless they are, because of extreme current weather; in which case you're in for it, of course. If A/S will turn your trepidation into confidence to make a trip in such weird conditions, then A/S are your solution. The rest of the time (99% plus), you will be on tires that don't corner as well; but the up side is they are UHP for speed and they are quieter and ride softer. :D

The best performing UHP A/S Tires (Pilot Sport A/S3+, Bridgestone RE980AS, P-Zero A/S Plus, Conti DWS06, etc) actually will objectively out-perform a mid-tier UHP summer tire, on dry warm pavement. Most of that comes down to those tires really just being their summer counterparts with a slightly harder compound that can handle cold better. They also do almost as well as anything that isn't something crazy like a Pilot Sport Cup tire if you talk strictly straight-line traction, especially cold launches. The big difference comes in the amount of heat you can put into the tire before they start to give up and how the tires behave in corners and even then it isn't something I'd worry about on the street. You'd see the difference on lap times, especially if you ran hard multiple laps.

Check back in the thread I started to review the Motivos, when I mentioned that they didn't have better wet performance as advertised. I'll put that below:

"The last couple of days driving in rain has let me find the wet grip limits of the Motivo. While it is advertised as having better wet grip than dry, I'm finding the opposite. To be fair, the issues I have experienced comes to light when cornering and turning. This morning the roads seemed overly slippery and it was mainly drizzle not actual rain like yesterday. I could feel some slip on local streets going through curves so I backed off a bit. A guy in a Taurus decided he could do better than the Stinger zipped past me and almost lost it. Seemed like one of those folks that don't want anyone in front of them, I passed him on the right as that's the lane I was in and continued into the next curve where again I felt a slip of the tires and pushed on as it straighten up as I could see him having trouble slightly behind me. When I was further along before the next light, I stomped the brakes to test the stopping ability and the ABS activated a bit more than I expected for the speed I was traveling.

I'll say this up front that I'm the type of driver that drives the same wet (a bit more cautiously) or dry and look for tires that can perform great in both conditions. The Michelin's held up much better in this regard but the Nittos are quieter and ride more comfortable over ruts and imperfections, yeah, I'm getting old and want a bit more comfort with my sport. LOL! Guess I'll need to tone it down for these tires. In my experience, these ride like Pirelli P7 AS+ tires, which are GT tires, not UHPAS. Really waiting to see how these do in the snow."

As Oryan mentioned, those top manufacturer's tires are going to perform much better than the Nittos, their road noise might be higher than the Nittos and they may also be firmer but if one can get that level of comfort and noise level on those versions, it would probably Pirelli but they didn't have a set for our car or that's what I would have gone for. With this one being better sealed than my 2018, the Michelins are faring a bit better now that I have had 600+ miles on them. Put them back on last week and today was the first real rain we have had since and had a couple of hard braking events, when folks just decided to change lane without checking, into my lane. I was on the horn hard and had I not been able to cut the speed fast to avoid them, they would have hit me (42 degree this morning). This happened in the dry yesterday and this morning in the rain. Some kid in an Accord, leaned back in a hoodie, didn't even signal or looked over, decided to just come over. Don't know if he heard the horn or just realized I was in the lane when he almost hit me and he just went back into his lane as if nothing happened. Similar thing this morning in the rain. the one positive thing I did note for the hard braking was that not once did the ABS come on, but I did feel a bit of vibration on the driver side wheel after the braking events.

I now have 2 sets of summer Michelins to rotate through, along with the winter tires. The Pirellis will have to wait for sometime in the future. With the 2019, the noise level isn't as bad as it was in the 2018 and surprisingly, the ride isn't has bad as it was, on some of the crappy roads I commute on, in that car either. Once the full summer hits, we will see if that is the same. Sway bar set to go in later and I may also put some springs on as well.
 
Thanks, @Waynerm002 for the refresher on the Motivos. I remember reading that before. But after our shared experiences on the Motivos, your assessment is more informative than when I read this originally (before I got my Motivos on, iirc; I was still looking into it).

Couple of things: to be a better performing UHP A/S tire than the Motivo, it seems that the "best range" shifts, that's all. "Better" will be in a speed vis-à-vis temperature range. So if the Motivo is softer than another brand, that other hypothetical brand will perform better on warmer surfaces than the Motivo. If the Motivo is harder than a performance A/S, it will outperform said-brand in warmer conditions, but lose out when it is colder. So, to get better warm and dry high performance out of an A/S than the Motivo, the other brand is going to give up the softer more comfortable ride as well; it is going to ride more like a Pilot Sport tire.
 
There are a multitude of things that go into manufacturing a tire and the big guys trade places for best performance wet/dry/snow, stopping distance, cornering grip, comfort, etc.. Over my life of owning cars since the 90's, Michelin's were always talked about as the "gold" standard for being comfortable, have great handling, etc., but have always been pricier than others. The Nitto Motivo in my experience, ranks among the best for comfort and a quiet ride as well as the Kuhmo ASX when it was first on the market back in 2001 when I had it on my Audi A4. That one was the smoothest, quietest tire I can recall and it's wet weather performance was great on the Quattro. When it comes to sporty driving, it sucked on any type of hard cornering, the sidewalls were way too soft for that kind of work.

Bridgestone, Continental, Michelin and Pirelli I find have been tops for my use. My first foray into Generals on the Optima hybrid has been a great experience so far. On that same night when I had the accident with the Stinger, I was able to drive the hybrid around at higher speed, with better grip, starting, turning and stopping than the Motivos. For me and my driving style, when I want have some fun, the Motivo would limit that for me. I'll take some road noise for better grip but, I really wished they had made the Stinger's cabin as quiet as the K900.

I've read on here that the forward part of the Stinger's cabin is pretty good, but there is virtually no insulation in the hatch floor. And I think that somebody pointed out that the rear passenger area of the Stinger is not as insulated ad the front. A couple of owners some months ago described how they've added sound deadening liners to their hatches. But I don't recall hearing how much that effort made in making the cabin over all quieter.

I remember one of your first observations about the Motivo was that hard cornering caused the tires to slip a little compared to the Pilot Sport. I discovered the same thing. And understeer. Soon I will be putting the Pilot Sports through my "test curves" for comparison, after a winter of driving on the Motivos. And with much lighter rims in the mix! :D

I've driven a 2.0T with the Bridgestone Potenza RE97AS-02 (I think it's the same tires on the GT with the AWD AS package) and I didn't spend too much time with it because I didn't like the noise it gave off. It made the Stinger louder inside than my Optima and I was hoping for it to be as quiet as the GT or at least quieter than the Optima. Those tires aren't highly rated (at least the original version, these are supposed to be 2nd Gen) so if I ended up going with the 2.0T and getting those tires, I will dump them in a short period of time if the new versions are noisy.

Checked tirerack.com and there are no reviews on them yet nor have they done any testing. Would be curious to know what owners with them think. Maybe a few of you can post some reviews on TR for folks to get some opinion on them.
 
Recently bought 2019 2.0 with same Potenza tires. Needed several rebalances and they still vibrate more than they should at
freeway speed.
 
Ditch those tires fast! Do a +1 upgrade and go with some 235/45 18s instead, if you drive hard, look for something in the Ultra High Performance AS category. The BFG GFORCE Comp-2 AS are pretty good, I have the General G-MAX AS05 on my Optima Hybrid and I really enjoy them on that car. Bridgestone has the relatively new 980 AS which received a good rating from Tirerack.com and Pirelli has the P Zero AS PLUS which is also a good performer and for the new Sonata and upcoming Optima, the Koreans have Pirelli's as their tire of choice on those vehicles.
 
I remember one of your first observations about the Motivo was that hard cornering caused the tires to slip a little compared to the Pilot Sport. I discovered the same thing. And understeer.
The OC in me must correct this, since I just noticed it after all this time: the Motivo would produce jabs of "oversteer" not "understeer"; back when I wrote this I was mixing the two terms up.:rolleyes::p (I still switch them sometimes, but it's because of "Reversitis" - the malady of things going opposite in your head/memory, and you remember them backwards: this is a real deal: I don't know what else to call it: because it isn't left-right dyslexia or anything like that: it's more strange than dyslexia.) I am very clear on what understeer and oversteer are, just not always careful to make certain that I have written the right one. Carry on. :)
 
Bumping up an old thread: Just got a new 2020 GT base and noticed a lot of road noise so wanted to touch back on this subject:

- The tires are Pilot Sport 4S summer tires on 19" stock wheels and they are new. I can hear a sort of "hollow" noise from what seems to be the front tires whenever I am at a speed of 30+ mph, its even worse when I am on crappy roads and when I am doing sharp turns at low speeds, particularly to the left. Also, I hear a similar hollow noise whenever I drive over a roadbump from the front tires (none from the back). My psi while driving is usually 40 front 43 back via TPMS. Since this thread is a little old, is it normal for this tire/road noise to be apparent?

Also has there been any experiences with tires mentioned/not mentioned on this thread that provides a quieter ride?

what pressure is indicated on the sticker on the driver side B pillar? It sounds like you’re way over inflated.
 
______________________________
The B pillar sticker indicates 36psi for both front and back. But if I recall the pressures should be 36/38 according to this forum. Not sure if there were changes but I stuck with the sticker recommendation.

My tires' psi cold were 37 in both front tires and 41 in both rear tires. I let air out and got them all to 36 psi however the hollow sound is still there. Also I can notice the sound most loudly around ~15mph and on certain roads. There is an obvious hollow sound in the front tires but none in the back when I cross a road-bump.

Could this be a balancing and rotation issue?

I’d definitely have the tires examined. Something isn’t right. Truly, the entire front end suspension. It sounds like a rotation issue.
I figure, if Kia wanted to correct the tire pressure they’d do a recall to change the sticker. I’ve always followed that sticker for OEM spec tires.
 
Yea, those were my thoughts exactly. I'm going to get it checked out and will report back when I hear the results.
 
So I took my car in to the dealership and they couldn't find anything wrong with the tires and suspension. I will say that while I was driving around with a technician in the car the aforementioned tire noise seemed to minimize significantly and essentially dissipated. The dealership is located on the north side of town and the roads up there are very well paved and maintained, unlike the south side where all the roads are garbage. It seems like I can only really hear the "hollow" sound when I am driving on uneven/bad roads, and it sounds like someone is blowing over a glass bottle.

Is it possible that the sound is normal based on the thin nature of the Michelin PS4s? What's strange is that the noise only comes from the front of the car, and whenever I go over roadbumps, I only hear the hollow noise from the front set of tires, with the noise being more apparent on the front right tire.

In terms of driving the car I am not noticing any steering wheel vibrations (unless I am turning/braking on shitty roads) and not feeling any pull - so I believe the dealer that everything is sound with my suspension at least.

With that being said, should I go to another dealer to get a second opinion?
