Left Front Tire Wearing VERY Fast

  • 14 posts

    Hey guys,

    I have Continental ExtremeContact DWS tires on the tC, they have approx. 13,000 miles on them. I rotated them the first time at about 6,000 miles, and just now (about 7,500 more miles give or take). When I was rotating them (front to rear on same side), the right side tires were about the same, probably 6/32 or so, the "S" on the tires was just wearing away. On the left side however, the front tire has very little tread (you can see Lincoln's head on the penny = 2/32 I think?) while the left rear has more tread than the other tires. So that means a tire rated for 40 or 50,000 miles only lasted about 13 - 14,000.

    Now for the really concerning part. When I had the car inspected in March, 4,000 miles ago, the tire had 8/32 of tread on it. An alignment was performed back in January so while it's possible, it seems unlikely that the alignment could be that bad after a few months, especially because this extreme wear seems like it started sometime after it was inspected.

    What do you guys think could be the problem?

    How should I continue from here, as far as taking the car in and showing Walmart (where I bought the tires)?

    (Btw, sorry for the lengthy post, and sorry if it's in the wrong place)

    Thanks in advance!
    If you had bought the used, its possible and i have seen it, that it was in an accident and the frame rail is pulled down, some how some way the alignment specs were dead on, but cause of the frame rail being down the tire had a weird wear in it. That might be the case, it wouldnt really be the tires fault if its happening to the one side only, another is watch for proper inflation on the tires. Last but not least make sure there is not 50 of those stick on wheel weights that mechanic shops use to balance wheels on the inside of the rim.

    I bought it used but this is the second set of tires I have had on the car and this did not happen previously. I would think if a frame rail was bent, I would have encountered this previously? (Although feel free to correct me if I'm wrong, it would def not be the first time lol)

    I forgot to mention that I checked the inflation and it was at 31psi, I think 32 is the recommended inflation, so hardly enough difference to cause concern. Also, the tire seems evenly worn down.

    I don't think it was from something Walmart did when the tires were installed because it seemed to wear properly for the first 8,000 or so miles. As of the inspection, it had 8/32 on it, same as the other front tire. Since then however, it has been worn down very quickly.
    No you are right if it were a rail it would've happened before. You running lowering springs/coilovers, maybe you have a bad shock, or a stiff shock(hahahaha he said stiff) which would put more pressure onto the tire, causing more traction and possible tire wear.
    Well first things first. You need to post pics of HOW the tire is wearing.

    Simple facts about tire wear.

    One shoulder worn = bad alignment (tow in/out) or driving in circles
    Both shoulders worn = under-inflated tire or overloaded vehicle
    Center of tread worn = over-inflation
    Entire tread worn evenly at excessive rate = spinning tires or (rarely but possible - defective tread compound)
    Entire tread worn at a taper = bad alignment (camber)

    That should give you a basic idea of what to be concerned about.

    +1 to all Immortal had to say, and I'll add this...

    6,000 miles and 7,500 miles is WAY too long to wait to rotate a 45-series (aspect ratio) tire like what we have on the tC. Toyo/Nitto for example require for warranty issues that a 45-series tires (the 45 in a 215/45-17 tire) be rotated at 3,500 miles or warranty issue related to treadwear will not be honored.

    I think you've waited way too long to rotate them and you're now seeing the life be literally rubbed right off the tires. On the next set just rotate them earlier and you'll have a much longer life as long as the frame,alignment, etc all check out to be ok.

    All the suspension components are stock, I only have an ingalls 4 pt brace.

    Spinning tires?

    Maybe it is a defective tire with bad tread, wearing off 5/32 in 4,000 miles seems like something is either really wrong with the tire or the car, the car doesn't feel any different....

    I have a few pics I took while doing the penny test, I can post those after work.

    I performed measurements in the different grooves going parallel to the way the tire spins and they were all the same. The tire seems to be wearing evenly across the surface.

    I have read that if your toe is out of alignment, it can cause the tire to wear evenly but very fast because the tire is sort of "dragging" instead of rolling properly, is this true?

    Also, I read that maybe some kind of suspension bushing could be bad? Is this a possibility? How would I go about checking these bushings?

    Ok I will rotate more often. Just for general information, I'm not typically hard on tires. My previous set (ones that came on the car) were Nitto NeoGens, which I rotated about 5-7,000 intervals and I got about 25,000 miles out of the tires.


    EDIT:

    Here are some pics I took. The tread appears to be worn evenly across the tire (even if it looks a bit off in the pics, I probably had the penny tilted or something).





    BUMP for help!


    Any other thoughts? (Please see added pics and questions in above post)
    Id it possible you may have bought a rethreaded tire? I have only heard of this, not yet have i seen it.

    the nitto neogens are designed for crazy-camber, lowered suspensions which to me means they're designed to put up with a LOT of abuse over time! that may be why they lasted longer with longer rotation intervals.

    about the tires wearing so quickly, I'm wondering if the tires were more than a year old when you bought them. On the sidewall there is a DOT number then inside an oval is a four digit code like 4412. The first two digits is the week of manufacture like in this case 44th week, and the 12 is the year 2012. If your tires were not fresh, I consider 6 months or newer to be fresh tires, it's quite possible that the tire began to "harden" as it aged and that caused an acceleration in the wear.

    I know that when I've gotten closer to needing tire replacements the tires begin to wear more quickly, plus ride a lot harder as the compound in the tread hardens up. It could explain why you're getting even wear across the tread but quick wear.

    check the date codes, might be one of them is older than the rest.

    EDIT: you asked about toe setting in the wheel alignment, yes it can cause quick wear if not set correctly. it's more of a "sawtooth" or "feathering" across the entire tread depending on if it's toe-in or toe-out. One feathering would be from the inside going out or outside going inward. But as you said you don't have any of that just really quick even wear. I'm still thinking it's a tire age issue coupled with way too long of tire rotation intervals. I know I've seen tires that people have waited 8000 miles to rotate them and there isn't much left, even though they're rated for 50,000 miles!
    First... thanks for posting pics.
    1. I dont think you have an alignment issue.
    2. I dont believe you have been spinning that tire. I sold tires for 12+ years and i can read treads pretty well.

    Do post the date code.
    • Edited 1 times, last by carguy978 on .
    Ok guys, I got the date codes:

    3 tires (including the bad one): 3111

    1 tire (the one worn the least): 2911

    So I guess that means my tires were a year old when I got them in September 2012......

    I also lifted up the drivers front wheel to see if there was any play (maybe a bushing bad or something) and there was NONE. As far as I know, there is nothing wrong with this car at all. Just that 1 of these tires wore MUCH faster than the other ones.

    So what are your thoughts on the date codes?

    Also, has anyone had any experience with Walmart tire prorating? I'm hoping to take the car there and show them that the tire wore a lot faster than the other ones. Hopefully they will help me out but I'm not so sure....
    Well that s well within the 2 year restriction... or at least, within it.
    Funny how the best tire is 10 weeks older than the other 3.

    Oops!

    The date code is 3111, not 3911, that was a typo (I have edited it to be correct). Not that I think it would have any effect, but just want to be correct.

    So do we think it is a case of a defective tire?
