weird tire wear pattern. stock tires. stock rim. stock suspention. stock tire pressure what's up with this?

[labikesrcool]

so first off i realize that these tires are extremely wore and illegal and whatnot. i drove a different car when it rained. i was trying to get to winter and have failed. i am not necessarily disappointed in the 35000 miles i have gotten out of these. I check tire pressure every week and inflate them to stock door 34front 32back.

i have weird tire wear on the insides of some of my tires. one has worn to the point of ripping and starting to delaminate on the inside. here are some pictures of the tire.







other tires.




so does anybody know what's going on? they look similar to this guys tires.
http://www.mazdaspeedforums.org/foru...ls-susp-36756/
but he had bigger tires. these are stock.
it seems like stock tire pressures are a bit low.
from what i've read this may be too much toe out?

needless to say i'm getting new tires. any suggestions? there are some Hankook Ventus R-S2's on tirerack for 85bucks a tire on closeout. the reviews aren't awesome but does anybody here have any experience with them? any other suggest tires?

I would say it looks like your car needs a four wheel alignment and that is rubbing on something when you turn the wheel really hard to one side

[SRTie4k]

If you got 35,000 miles out of them, toe setting is not the issue. It would be very obvious if your toe was out of whack - you'd literally get 2000 miles and they'd be bald.

That looks more like rubbing to me. If it were camber, you'd see more even distribution of wear towards the inside/outside of the tire, but since it's only on that one spot, it looks like you're somehow rubbing your perch or something inside your fender well.

[Evo8blewbyu]

I think it's definitely a rubbing issue. Could be something between your tire and the ground. would start looking for something there.

[labikesrcool]

the grove is the shape of the part of the perchmount that the end of the spring is at. but no signs of rubbing.

The tires tread depth are perfect for handling ,that is what I want my tires to look like on my car if Im racing, the less tread the less the tred blocks squirm. Back to the issue it looks like either rubbing ,toe out, or you hit a curb and threw out the toe recently. The toe doesnt have to be out from day one it can get knocked out. And based on what I see ,which is the outside has more visible tread than the inside I would be willing to bet that it is a toe out condition, that is you may have dinged a curb or something and geaked the alignment . But in either case you need get an alignment ,you need to look at it as insurance for your new tires. Good luck and keep us up to date as to exactly what the real issue was ,I would like to know for my knowledge data bank ( my own brain)

Speakin the truth

[SRTie4k]

An out of spec toe would not cause the tearing you see at the threads. It's very obviously rubbing a sharp piece of metal.

[Fratman]

I am assuming that these are the front tires,If you rotated the fronts to the rear , did the new ones up front do the same thing? Did the rears also do the same? Also based on your pix the outside has more tread ,I would expect the outside to have more ware because of when you turn the tire rolls over a little and the outside shoulder should have more wear , if you drive it at all hard.


Fratman

As far as the cords showing if it gets run long enough it will eventually wear down to the steel belt , I can testify that those steel cords will tear your hand up but good ,they are nasty.

[labikesrcool]

so the shape of the cut is exactly the shape of a part on the spring perch that is closest to the tire. where the end of the spring sits.




what's weird is that the paint is just fine on the spring perch. it happened gradually over time and the drivers side has some rub but not anywhere close to the passenger side. the problem is for sure happening when the tires are in the front.
so anyways is it possible that the spring perch can be rotated a few degrees so that it misses the tire? i have never done any suspension work to know.

edit: that perch can't get any closer to the tire right? so that can't be it. i can't find any other rubbing area's. any ideas?

I have 245/45/18's on my rx-8 wheels and the perch still does not touch the tire.
I got about half of that spacing you have in that picture.

Are you doing a lot of power turning?
When was your last alignment?
Did you buy your car new?
Do you do alot jumping with your car?
What is your credit card number and exp date?

if by power turning you mean spinning the tires while turning no.
in japan.
yes.
car only leaves the ground so i can get under it for an oil change.
AMEX 4875 5422 2665 5488 12/21/2012 and the number on the back just incase you need it is 542

[bioevolve]

I don't like AMEX! LOL
Besides that is a VISA starting number lol.
AMEX has 15 numbers not 16 and AMEX starts with 34 or 37.
oh forgot: AMEX has 4 digit number on the back.

Maybe an aggressive alignment for road racing was done?

[reddeerspeed3]

i dont think you have an alignment or rubbing issue. the first pic you posted doesnt show an even white line that would indicate rubbing. your back tires have a bit of positive (i think) camber for handling reasons. this will wear the inside of your tire slightly more than the outside. you've worn your tires right to the point that the inside edge has started to seperate because of the force exerted by the air pressure in the tire. i'd bite the bullet and buy 4 new tires before you have a blowout

[6262ms3]

hmm, I didn't let my stockers get nearly that bald before replacing them but I did notice mine were more worn on the inside similar to yours. I figured it was due to camber and hard cornering, but I think I'll get an alignment just to be on the safe side.

[Switters]

This is an alignment issue. I see cars all the time with tires worn like this. BMW's are the worst because of their factory toe and camber specs. Go get the car aligned. Ill bet it's out.

I totally agree. I never set any 3 or 5 series to factory specs on a BMW. With their settings you'll never get good tire wear. The pics above show a toe issue. With the mileage received from them I wouldnt suggest more than an alignment. Nothing to worry about at all.

[Rhylian]

mine looked like that as well after about 25k,I believe mazda just has an aggressive cornering setup as far as alignment goes.

Nice 6 year thread-necro.

[sheston]

Since it got resurrected, Mazda doesn't have an aggressive corning set-up, they just wear thru tires. I got 9K out of my "stock" alignment, fairly good tread, but bald where the pictures show threads. Given a couple k more miles, I'm sure mine would have looked like that.

Got a real alignment and haven't had the issue thru 2 other sets of tires

I just changed my factory set of tires a couple of months ago with that identical wear pattern. I could feel it when I drove and thought I had bent a rim or something because the steering wheel would wobble at low speed. 24,000 miles, which is shit for tire wear. Ever since I put new tires on, the torque steer has been ridiculous. Tire shop alignment check came up all green on the computer printout. Makes no sense for a factory alignment to eat through the tires so fast on the inner corners of the tire. It feels like a combination of camber/toe-in, like the tires are only riding on the inner corners. The rest of my tires' tread had many miles left on them. Pissed about the waste of tire life and I can't believe the dealer didn't notice it on my rotations. I would love it if someone knew more about alignment settings to compensate. I can't afford to waste my new tires like that.

Post up your actual numbers.

[lnumbp]

Also, check both lower ball joints next time you have the car in the air. I've had 2 sets go out over the past 50k miles. The result is negative camber and toe and will cause inner tire wear.
