Widest Safe Front Tires?

[Rufus]

That wider tires comparison video says "yes and no". Yes on dry surfaces, the wider rears add "gription". No, on a wet (sandy?) surface, where the moisture has further to travel to get out from under the tread. There is the issue of changed handling characteristics. Oversteer and understeer are affected by changing the width of the tires, front mostly but also (iirc) the rear.

I thought only my wife used "gription!" where are ya from originally?

Utah, originally and still. It's a descriptive word that I got from a friend. But he's a Utah original too. I don't know where he got it from.

He wouldn't happen to be a tradesman who's also Mormon, would he? Because that's the stock my wife comes from!

Ah, Mormon. He is a dry Mormon, that is to say, he was never dunked, aka baptized, even though his older sister was devout and I believe his mother was baptized, but she never affiliated. He did go to church with me a few times when we were kids, but it didn't call to him and nothing came of it.

Here is said article+video:

I think it is worth a read/watch to help inform what direction you want to go in.

This test is bogus. It uses 3300 lb underpowered 320 i and shoves big 255 tires on skinny 7.5 inch stock wheels. No surprise that there wasn't much performance increase. Also suspect of the driver derived performance on track. Empirical g data is always better.

With proper rim size on our much heavier and powerful car wider will be better. We are under wheeled and tired for a large 4000 lb sedan. 245 front and 275 is still pretty narrow for our car so sort of laughable if anyone thinks that setup would be slower. Yes you want wider wheels as that influences tire performance as well. but dang Stinger has narrow wheels and tires. Heck my stock 2800 lb Honda Civic had wider 235 front tires than Stinger. Our car is heavy enough to get most wider tires up to proper operating temps. And yes if you put a wide summer tire on your car it will be more prone to hydroplaning in wet. ...Duh

About the only thing that Japlolicker test shows is how to make a car handle badly. LOL! Yes if you put big rear tires on car and don't get appropriate stagger up front understeer.

Did anybody try 225/45 on front and 255/40 on rear? I.e. +5% on both ends? Have difficulty to find studded winter tires for native size (225/40 on front and 255/35 on rear) here Wanted to buy Continental but have only Nokian and Michelin. For bigger size choice is better.

Each tire manufacturer will have specifications as to what width rim each size can be used with. I know this thread is about clearance but you must ensure that tire can be run safely. Going wider means the bead may not be seated correctly.

Morky, I didn't see your car up on their Facebook page, you should send them some pics. I bet they'd post them.
You'd be the first Stinger up there.

Yes I agree with what you say there eflyguy

anyone can fit tires or rims that may suit and look good too but i think some people need to know more by asking more from the experts and perhaps do their own research, like here and get to know how for sure before making a choice that may be very costly not just for the choice of wheels but potential trouble one day sooner or latter.
For ME was not to have any issues now or later because of just the looks and fitment
Insurance, Safety, Manufactures Warranty , The Law of the region, and each car's specifications on Maximum and Minimum Limits
(Label is on Pilar at the driver's side door ) on the Stingers!
For me, I went for the Max within the Required Specifications of the Car Maker of the vehicle , the Law, Covered by insurance, and I chose what was safe from the tyre manufacture to the stock standards of my vehicle to the performance and handling as close or better as is stock
so looks with safety for me.

looks with safety

Could be a moto or slogan. I wonder how you say that in German. For some reason it called to mind "Kraft durch Freude", "Strength through Joy".

So I just got a set of tires and for the factory Kia Stinger wheels and they are 245/35/19 for the fronts and 275/30/19 for the rear they look slightly wider and the grip is a bit better especially over those summer tires. It appears as if I still have some space in the front since the tires are slightly stretched. I may go for 255/30/19's in the front and 285/25/19's in the rear.

Do you want to look like that? Your speedometer is going to be off, and that might be too much OD difference front to rear for an AWD GTS. (Note: I am using one view to see the cross section of the front and rear tires, ignore the clearance info.)

There is nothing stretched about a 245 on an 8" wheel, that is a max recommended width: your 275 already looks bulgy in the sidewall on an 8.5" wheel. I like the look of a sidewall beyond the wheel too, but on this heavy car, cornering "spiritedly" is going to have a lot of sidewall flex with your proposed setup: might even be dangerous handling-wise. Anyway, it would give me trepidation checking it out.

Following! Just had my 19 GT2 serviced and was told that I needed new tires just after 19,000 miles. I am considering going a bit wider on stock wheels as well. Outside of the stock setup, is there a thread that suggests the best case scenario for both rwd and awd, with/without spacers for our stock wheels? Saw an M2 today with I believe 245/35/19 fr and 265/30/19 rear. I would be surprised if our cars cannot go much wider front and back without issues. I have a 91 330ci that was once staggered 235/35/19, 265/30/19.

I'm still learning but here is my current set up after just under 18k miles 245/35/19 for the fronts and 275/30/19 its handles great!

Did you use any spacers? Wondering what size spacers to get the tire just to the edge w/o any poke!
