2022 GT Line - Any changes in wheel/tire sizes that fit?

[wheezy]

Guys, sorry for the dumb question. I'm totally new to the Kia world. LOVE my 2022 GT Line (I'd kill myself if I had any more power and quite pleased with the "little" 2.5T)

So... I may have jumped the gun and got excited looking at wheels and tires. I came across this post: on extreme customs - can't post the link because I'm new here. So information below.

And placed the order for that exact combo. Then realized hey dummy, mayyyybe there's a difference between a 2018 GT AWD and the 2022 GT Line RWD .... Can't seem to find a "for sure" answer.

So here I am. You guys got any good news for me??? Thank you in advance for your time and info!

Why 20s? More weight and increased rotational mass (due to the distance) will make you go slower , less agility, less tire for tire deformation over bumps and surfaces, etc.

Is there a good reason for 20s?

My SS 1LE track car comes with 20s, but it really should come with 19s like the ZL1 1LE.

There are no changes to the 2022, I've checked my front strut clearance, it's real tight with the stock 34 offset rims. 35 should be fine, but that's a nice round number to make your limit at and verify fitment or make sure you can get a refund if you try larger. The back has a ton of space to suck the tires in.

Let me run your numbers through the spreadsheet I created:

 

[RM7]

So based on your numbers, I'm getting that your front tires will stick out 10mm more than stock and the rear 30mm more. About 22mm of this is due to the rear rims being wider. This might exaggerate the effect that you have by running such a narrower front tire and lead to some pretty massive understeer?

 

[MerlintheMad]

Yeah, watch out for the understeer, but your car's stance will look very cool. Hopefully that brand of wheel and offset will clear the front suspension okay: if not, then spacers time.

It's more about looks than anything else. This is just to take the wife to dinner and cruise around town. I'm an offroad guy, the little 2.5 is plenty quick enough, whatever performance hits I take, I doubt I'll notice. I wish I could post the link. If you google "gray kia stinger bronze wheels extreme customs" it should be the first thing you see. It's a 2018 GT AWD with that exact combo, and I love the way it looks.

This the one? I like it very much.

That's the one! Please don't laugh at me, but I had to google understeer. So, sorry for more dumb questions, would adding just a rear sway bar be a good idea to help alleviate some of that understeer that will be introduced with the staggered setup?

That is a smart question: one I could not have framed a couple of years ago: in fact, I used oversteer and understeer bassendackwards, so a member helped me out with this:

Wider tread in the back pushes into understeer territory; stiffer sway bar in the back enhances oversteer: so, yes, a stiffer sway bar in back will allow you to use those 10" wide tires with less understeer. Keep in mind that the stock Stinger already tends to oversteer. When I put my rear bar in, I was still using the two terms wrong and thought (mistakenly) that I was addressing stock oversteer: when in fact I had created more. Hah! I adjusted easily enough. But when I put my front bar in a year ago, man what an immediate difference: the oversteer is gone (unless I push into the realm of making tire noise in the curves, then I can start to feel it still there, but very much reduced).

 

[wheezy]

Hahaha, I love the graphic! OK, I'm going to order up the eibach as I get a deal on their stuff and I like that it's adjustable so if I add the front I could still have soft front / stiff rear. Again, performance isn't REALLY that big of a deal for me at this point but I'm having fun learning and I do have a round about near my home that I've been taking a little faster each time. LOL... I also tried launch control for the first time yesterday. We'll see where this thing ends up, as long as it ain't into the wall, I'm happy.

Just talked to the boys at eibach, looks like I might get to be the Guinea pig for the 2022 2.5 stuff. We'll see if they give me a call.

 

[MerlintheMad]

I don't think there is any difference in the suspension in your '22 and my '18, aside from ECS or the lack thereof.

Well, just to add another dimension: Proper handling isn't for the things you plan for, it's for the actions you have to take when you didn't plan for it.

IMO, you should be putting wider tires on the front and less wide tires on the rear. 255 would work great in the front (and the rear), but 275 or 265 would start to bring this back into reasonable territory, maybe only stagger half an inch instead of a full inch. Or if you are dead set for 245 front, 255 or 265 rear. What I'm realizing with this car is they didn't design in as much leeway as other cars, so while you can still run some wide stuff, you just gotta keep it reasonable.

 

[RM7]

Also, you mentioned that your car is RWD. Adding a stiffer sway to the just rear to counter the extreme staggered effect is a bad idea. RWD cars especially come with weaker rear sway bars so they can put the power down. While you may be able to dial out understeer, you will introduce lots of wheel spin and skipping under power. Your creating a problem with that radical of a staggering and then trying to solve it with something that will create another problem. In some autoX events, people will remove their rear swaybar for this very reason.

 

[RogueIV]

This stagger isn't that much different from stock, just an additional 10mm difference in the rear. It's best to just drive the car first, figure out how it handles then you can starting changing things if you don't like it.

I wouldn't suggest blindly throwing parts at it.

ROAD TRIP!!!!!

i have one similar that I drive pretty much every day to work but not as big....that would be awesome in my car....
