Explain the 18in vs 19in dilemma to me.

[jrhodes87]

5.8? Motor trend clocked the 2.0 at 6.6...

Well i'm just going off of what the above poster said. Idc what the 2.0 Turbo does I just want to be sure i'm not getting jipped on acceleration for having the 18's

They might be a tiny bit different but not noticable I would think. The 18s are 225/45 the rear on the 19s is 255/35. That will give you a .21% difference in speed at 60. Or another way of looking at it is the 18s will turn 800 times in 1 mile, and the 19s will turn 799.15 times per mile and the 18s will turn 800.85 times per mile. Definitely not a big difference.

18” Summer Tyres are not limited to 130/140.

18” summer times should have similar 0-60 times .... any 0.1’s difference you’ll never notice.

18” All Season tyres are limited to 130/140* (site says 130 but people say the linter doesn’t kick in until 140).

18” All Season Tyres will be slower 0-60 than Summer Tyres. By how much? I don’t think anyone knows.

The 18” All Season Tyres seem to be linked with the “All-Season Tyre”
Package.

Just don’t order with that, get the AWD, and you’ll have 19” wheels and 167mph.

If the snow is that bad in your area, then full winter tyres are better than just All Season. So you’ll end up changing them anyway.

So this dealers GT1 has all season tires I'm no longer really worried about top end speed I just don't want the 0-60 to be effected. If I were to put different tires on it and change out the all season tires would that improve 0-60.

EDIT: I take this back, his email simply says "The vehicle is AWD so it would have the 18in tires"

it doesn't say anything more then that

 

[jrhodes87]

IDK if anyone can tell what tires those are

Hard to say for me not knowing the tires by look but: My guess is 18" All Season Bridgestone Potenza RE97AS-02 all-season. The sidewall of the tire is pretty tall and there's a lot of structure (small extra tiny slits in the main knobs typical for winter tires, although usually wavy there and labyrinthine edgy structure on the flat areas further inside) in the rubber, indicating it is not the 19" dry weather tire (see for instance http://i.imgur.com/xO0W3pf.jpg)

But again .. this is an educated guess.

I ordered my GT1 AWD as a build car. The ONLY option for wheels and tires was the all-weather 18" and it was an option you had to choose. 18" are NOT standard on the AWD UNLESS your dealer ordered them that way. If you don't choose the 18" you get the 19". Apparently some dealers just used what they thought was common sense and ordered all of their GT AWD's with 18" wheels. That may be different in other countries like Canada, as there seems to be a long list of variations on the same theme with the Stinger. The dealer post above in @jrhodes87's post might apply to all the cars that dealer has or ordered, but it is not true of all GT's.

And this thread is the first I've heard of any 18" summer performance tires, so I question that. No such option on my order form in the U.S.

To clarify, the all seasons being slower to 60 is a function of a lower level of grip on dry/warm pavement from the tires rather than anything the car is doing.

In wet 30 degree weather the all seasons are likely to be faster to 60 than the summer tires.

Ok so this isn't a limiting factor based on ecu or anything but based on just pure grip. If I were to switch out tires to some higher end sport tires I'd be no less limited in my acceleration (given conditions)

 

[voon]

Allweather rubber and thread structure is not surpassing either winter or summer versions on their own. I'ts a compromise. Therefore, they (might) accelerate less quick ... this has nothing to do with the car electronics as stated. The limiter however is purely electronic and just doesn't allow you to bypass the allseason tires upper speed limit rating. Kia could simply unlock that later, but apaprently won't for whatever silly reason.

I.e. if you later put on pure summer sport tires, you will accelerate better. but you'll still be stuck at 130 mph max for no sane reason (well apart from traffic regulations and laws ).

 

[jrhodes87]

Yes I'm less concerned with top speed overall, I realized I've never been above 115 in my 3.8 genesis for any reason. I just want to be sure I have that acceleration.

 

[voon]

I doubt Kia has touched anything else there .. there's no laws on tires and acceleration/torque I know of, so you should be accelerating like any other Stinger below 130.

 

[DaJackson]

but you'll still be stuck at 130 mph max for no sane reason (well apart from traffic regulations and laws ).

And Kia’s liability if a customer has a tire fail above 130 because they fitted tires that can’t handle higher speeds.

 

[Mike_TX]

130 wtf is up with that I didn't realize it was that low. That's almost a deal breaker

Seriously? I keep seeing people saying this, but do you REALLY ever go 167mph? I know you can't do it legally, but I don't even know where you'd go to drive 167mph without risking your life or that of others.

I've lived a long tme without ever going over about 120 or so (in extreme passing situations), so if my car is limited to 130, I don't care.

No offense but read the rest of the thread

MT either got a bad one, or their regular tester was at home with the flu. Multiple others have gotten it below 6 seconds.

 

[Mike_TX]

Yeah, I read it all. All I can realistically conclude is that 167mph is basically for bragging rights.

One thing to note about the 18"s that I don't think was brought up yet, is the convenience of not having staggered tires, so as long as you rotate them you'll get a lot more life out of your All Seasons than the 19" summer tires.

Yes I saw that brought up quite a bit in the mega thread on this topic

 

[jwhollan]

I was told that in ohio, all awd were shipped with 18s, not sure if that;s true or not, but based on my search it seemed accurate to me.

Definitely not true. I bought mine just a few miles down the road from yours and mine is an AWD with 19" wheels/summer tires
