Another One!!

^^I think a tire needs a few heat cycles to "break in" for optimal grip. At least such was the case with motorcycle tires. Vibration usually means poor balance, or defective tire.

The real question, do you need PS4's for your type of driving. I had the PSS on the last car and they were definitely overkill for 98% of my driving. If I still had that car, i'd go with the PS AS4 next time around.
 
I think by now every stinger owner should realise these cars eat rear tyres even with moderate driving.

I'm 70 months in and at 70k km I'm on my fourth set. Thats km not miles. My last set lasted 15 months and 15k km. I do 80% freeway driving and live in the country with long straight roads. The nearest town is 30km away, I drive as most 60 year old do conservatively.

My 21gt Mustang is on 33k km and i was told ive got at least 10k km left and they are staggered 255/275 Michellin Ps4s.
 
First 3 years on the original Pilot tires and no issues. Within first year of the firestone firehawks, replacing my second tire. Hit something sharp and uneven surface, did not look like a pothole , coming off a ramp! Thought my whole wheel was going to fall off. Watched my tire pressure as it dropped! It might all be coincidence, but I am not seeing the firehawks in the cars future LOL!!
Well, if it's road hazards that did the damage, then it's not really the tire's fault. Any brand/model of tires are susceptible to road hazards. Plus, tires hitting road hazards are mostly luck of the draw... much like flying debris cracking windshields.

Will say what a difference…. Did a 2 hour round trip with the nitto’s from Brooklyn to Long Island to see a family member…on the Nitto’s it was sloppy and the sound is there…plus I felt everything every bump etc…when I got home I forgot my wallet…had to run back…I love driving really…I can drive all day…so was heading out and my tire store got my tires in today… had The tires put on and I did the same 2 hour round trip…HUGE difference….the Michelin’s Sounds way better I didn’t feel every bump and it felt tighter in corners and in general… I enjoyed driving my stinger again…the tire shop couldn‘t believe how new the Nitto‘s were…I had to toss them in the dumpster myself….. now if you love nitto’s cool but not for me…I really gave them a shot and I just hated driving…sometimes I think I’m crazy and I use my wife as a baseline opinion…didn’t tell her anything about the tires I talked really good about the NITTO’s because I didn’t want to place a Negative seed…she hated driving the stinger too…tomorrow she is hitting queens and I can’t wait to hear how the car feels to her now…to me the Michelin’s are in just another class…The Pilot Sport All Season 4’s is pure money…. I can’t recommend them enough.

No car eats tires like this, you have a significant problem if you’re going through tires at that rate. I have ps4’s and at 12k miles they still have at least half their tread life. My first stinger (GT AWD) I averaged 50k plus miles on primacy tour AS. I don’t expect to get that out of the ps4’s but definitely better than what you’re stating. I also drive primarily on straight highways and I’ve put 120k miles on 2 different stingers, you have a big problem with alignment or something causing extremely excessive tire wear.

I have the camber/ caster kit installed on the front and get even wear on my tyres so I'm at a loss at what it could be.

My best mileage was on the original tyres and thats when i had terrible alignment issues. A reoccuring problem has been the amount of toe out of spec on the rear passenger wheel.
 
When you're lowered it allows you to dial up more or less camber .Without this you have less scope. My caster adjustment had to be increased also as i had mad pull to the left hand side (RHD). This allowed for the left side to be moved forward to negate right for pushing to the left.

Not an expert but that similar to how it was explained to me.

If i had my time again i would not have lowered it, its been one big headache. I would go 20" wheels.

Can you share your alignment specs/report from your last alignment? I just had another alignment done and I’d like to compare if you have them. The caster/camber kit should help. It made a big difference in my Mustang. The way your car is eating tires is crazy, it would seem something would have to be pretty far out of spec to cause that. On my ‘20 I had the front out of spec minimally and it took about 10k miles of life off my left front tire, it was literally almost nothing so it doesn’t take much to cause uneven wear for sure.

Wouldn't you know i was cleaning the glove box last week and through out the alignment sheet. I was close to keeping it.

I realise your surprise in my tyre wear but all the Stinger owners i chat to have high wear too especially those lowered.

Stinger front camber and caster angles are non-adjustable. Toe angle can be adjusted on either side via the threaded steering knuckles.

I'd like to know what method of lowering allows you to adjust both camber and caster. If you lower via lowering springs, camber or caster angles might change slightly depending on your lowering amount, but they are not "adjustable" in the sense that they could be varied at will. Once assembled and lowered, what front camber/caster angles end up being are what you get. There is no adjustment.

Now, if you have coil-overs, then quite often they do have top plates that allow you to adjust camber by a few degrees. That is one main reason we switched from Eibach springs to Riaction coil-overs. However, I've yet to come across any coil-overs that allows for caster angle adjustment too. That is no easy feat.

Excellent reason for me to not lower the car, definitely surprising numbers but you pay to play and you’ve definitely learned that in tire bills!
 
Michelin tyres are great for performance hence they are on the car from the factory but they suffer the same damage from foreign objects as any other tyre, One of my MY 23 Stingers here arrived home with 1000kms on the clock and a piece of triangle galvanised tin was embedded in a rear tyre. One new Pilot 4S at $535.....note Michelin Australia is not stocking the standard Pilot 4 that comes on the vehicle for $100 less.....only the more expensive 4S which though has the identical tread pattern has an improved side wall............apparently

True, or as we say down here "Bloody oath"

I'm experiencing the same right now. Thinking of going back to a square setup. My current setup is 255/35/R19 in the front and 275/35/R19 in the rear. Hoping that a narrower rear tire may help with the wear but not completely sure.

Another thought I had, has anyone tried aligning the rear without as much toe from the Kia Specs? Kia factory specs have the rear toe'd in a bit. Wondering if aligning them straighter without as much toe would help with the lowered cars eating through tires? I've also noticed some squirrely behavior while driving in the wet.

Why did you choose to go with smaller diameter wheels?
And also, why are you using unequal diameter wheels? Isn't it causing TC problems? Is it AWD?

I think you're having a brain fart there. Those are tire sizes, not wheels.

I think his statement is fairly accurate. Those tire specs would about 1.9% difference depending on manufacturer. 255/30/19 would be 78.6" and the 275/30/19 would be 80.1". Rev per min would be 500.8 to 491.5. If the car is AWD that could cause excessive wear/strain on the tranfer case/torque converter.

I think you might not know how tire sizes work.

Both OEM 225/40R19 and 255/35R19 wheels (wheel+tire) have a diameter of 26"

His setup is:
255/30/R19 = 25"
and
275/30/19 = 25.5"

That's a significant difference.
