Widest Tires on AWD?

[4wheelpilot]

Anyone know the widest tires, front and back, that we can fit on the AWD?
Contacted tire rack and they said 235 is max width. Very few tires choices with that width in 18”.
Hoping the car can handle 245s.

are you going to use the stock wheel ? If so , thats the limitation

I have 225 front 255 rear could have fit 265 on 8.5 front rim 9.5 rear

Remember seeing with RWD rear tire is 255 width.
But with AWD, seems with oem rims and their offset, its 235 max width in front.
What offset is needed with 8.5 rim in front to fit a 245 width tire?

Very aggressive, fills the wheel wells perfectly.
What offset is necessary to fit s 245 front and back on an AWD?

Bumping this. My buddy picked up a Stinger recently and when driving behind him I noticed the tires looked narrow for the car (in my opinion). Staying with the stock wheels in the staggered setup on the AWD version, what’s the widest tires one could install on the Stinger?

"Narrow", really. Hmm. I guess I don't see this the same way, because I think the Stinger's tires are plenty wide. Why would a wider tire on the same rims be any advantage? Just looks? Sacrificing raw performance for appearance sake?

 

[Waynerm002]

I'm thinking a little more comfort and wheel protection from curbs and potholes. For performance, it would mean some 20s or wider 19s. While I have good roads in my area, my commute route has some crappy roads which can develop craters over the winter.

So how wide can we go with the 19" staggered setup? I'm asking tread width, not tire size. Right now the stock Michelin Pilot Sport has 8" front 8.5" rear.

Right now I am running 19x8.5" +30 245/35/19 all around. I am also lowered on eibach springs.

Why doesn't the OEM staggered arrangement do that? Why 8" in the front? Is it a handling thing? Do we just think that wider is better by default?

Merlin, those sizes are wheel size, not tire size. You'll notice the fronts have a slight stretch to them, according to information on TR, those have a thread width of 7.6 inches (Michelin lists 9.1" on 8" rim), the rear on the other hand is listed at 9.5"(michelin lists 10.2 on a 9" rim). Tire brands have different measurement with similar tires. As an example SilverNitr8 has switched to the BF Goodrich Comp 2 A/S and his front tires sits almost flush with the front wheels and on TR the treat width is listed at 7.8" front and 9.2" at the rear. Not sure if I'm reading all the specs correctly but visibly you can see the difference in how the Michelin sits compared to the BF Goodrich.

Normally staggered setup are used in a RWD configuration, the front handles the steering while the rear manages the power/drive. I'm not an expert at this but what I have heard is you need wider tires to provide more grip to better manage high horsepower rear drive vehicles. I'm sure the Stinger uses a lot of tech to reign in the power to keep us safe. Based on the power figures, I would have expected 8.5" up front or 9" all around. European vehicles typically have a wider setup while the Asian vehicles are on the narrower side. The Mazda 6 for example runs 19" wheels but those are only 7.5" wide, a 2009 BMW 535/550 had a staggered setup of 19x8.5 fronts and 19x9.5 rear, those cars were running 300/360 hp and torque. The Stinger has more power and torque than either and I'm sure it would benefit performance wise (if not also comfort) from some wider wheels and tires.

I would go for square setup with the 19x8.5 and use 245/40 tires. Anyone wants to swap their rears for my fronts?

Performance go to 20? Actually I’d go to 18x10 for performance. 20 inch is for looks

What's your goal? Are you just wanting more rubber because it looks cooler or for cornering grip, grip off the line? I have a stock AWD GT and it has no problem with traction off the line with the oem pilot sport 4's. Heres what I'll say about throwing a ton of rubber on the car up front, it will give your steering a bit more heft for sure and improve corner grip but at the cost of some acceleration. More rubber, equals more weight, which equals more unsprung weight. More rubber has both pros and cons.

Well, I'm trying to understand why Kia went with the tire sizes they did. Must have tested a bunch of them. They settled on a staggered setup for the best performance during "sport" driving. And they opted for all around compromise with the A/S square setup. So when we play around with this and that, are we improving the actual performance or hindering it for cooler looks?

 

[Waynerm002]

For the average car, the tire setup is a compromise of performance, comfort and fuel economy. We can all agree the Stinger is great but for some of us it can be better with a few tweaks. It has a great chassis already, I’m looking to do things to make it better for me.

I'm lowered and running 285s on the rear but not on stock wheels. I've seen pics of 295s (obviously not on stock wheels) but they will most likely stick out past the fender.

If you want a square setup you're probably going to max out at 245 or 255 with stock wheels, depending on what wheel sizes different tire manufactures may recommend.

This is all interesting information to tuck away for later. Thanks to you and et al. who know wheels and tires.

BMW 3 series has the same stock tyre size: 225 front 255 rear.
It is usually done to give a more neutral handling characteristic on rwd cars. If you go square, you will increase oversteer.
