Tires are worn on the Inside Edges

[94MuStAnGGT5o]

So, i just discovered that the insides of my front tires are really worn out, the tires are like new but the inside looks like it has been heavily used, the back tires are normal. The car is lowered but was not done by me, im guessing the previous owner messed up on something

it basically looks like this

how to fix it? im guessing readjusting ?

Thanks,
Marcel

You need an alignment.

Hey man, thanks for the quick reply

can i do this by myself or does a shop have to do it

how much will this cost me?

you have to get a shop to do it but looking at how low your car is you need cc plates. factory adjustment will not fix the problem completely

Yep CC plates and a alignment... Sometimes you can have someone that is skilled to drill out the factory rivets and get by without CC plates if you car will allow it.

A wheel alignment will fix it..prices vary I have paid from $49 bucks to $90...you may not need CC plates even if lowered ..check out the alignment first & they will tell you if they are necessary...I didn't need them on my car 1.5" drop all the way around but lower than that & you may. I put Steeda CC plates on later for around $169 bucks

You have a positive toe angle right now, Caster and camber plates are a must when you lower a vehicle. However you problem is toe

Pretty sure it's Negative Camber not Toe in or toe out he has on his car from the pic he provided.
It could be a Postive Toe, but when he gets a alignment they should be able to tell him if they had to adjust the Toe or if it was the Camber. Toe in or Toe out will cause steering instability also. With something that severe i would thing he would be having major problems.

Toe

Toe describes whether the fronts of the tires are closer (toe-in) or farther (toe-out) apart than the rears of the tires. Toe settings vary between front and rear wheel drive vehicles. In a front wheel drive vehicle, the front wheels try to pull toward each other when the vehicle is in motion, which requires a compensating toe-out setting. A rear wheel drive vehicle works just the opposite, necessitating a toe-in setting. Stated differently, toe is set to let the tires roll in parallel (at zero toe) when the vehicle is in motion.

toe being out will cause lumps on the edge of the tire, and can lead to that kind of massive damage, but more likely its negative camber as the car has been lowered.

in the picture the OP posted, the problem is toe.

His car is likely suffereing from both negative camber AND toe issues.

changing the ride height of a vehicle will affect toe as the tie rod angles become extreme and will pull on the wheels

I don't want to be negative or anything but it not ALLWAYS necessary to add CC plates if you lower your car no more than 1.5 inches! Most cars won't need them in my experience but a few will so why not try it first without? As long as you can adjust it into spec you don't need them on a lowered car. More drop than that & yes you need them.

(thats not his tire)

I am fully aware of how caster camber and toe effect tires I'm telling you it's a toe issue mainly could also be camber but the way the tread is in that pic it's a toe issue. If it had that much negative camber to only wear the edge like that, the inside of the tire would rub on the shock.

you are exactly right, but thats not a picture of his tire. he said "it basically looks like this" which leads me to believe thats just a google'ed image of a tire w/ inside wear.

we know the car has been lowered, which puts camber way negative every time. Thats where we should start.

OP, you may not NEED CC plates, but they are a great tool to have, I'd go ahead and get them, and then bring it to an alignment shop.

Wow I didn't even notice it said that above the pic, next time I will read a bit more carefully. I thought that was the actual tire. Ok so now I will remove my E-foot from my mouth haha. I was kinda wondering how he would have been able to drive it that long and not notice something was seriously wrong.


Ok new plan get c&c plates.

 

[MustangMoser]

lol, no worries. that tire looks like its about to blow, and i'm sure there were some massive drivability problems with it.

 

[ReplicaR]

When the tire looks like that, it's definitely more of a excessive toe issue than camber problem. What's more is that it's possible to have a perfect toe setting when you're standing still, but as soon as you start moving whatever is causing the slack in the steering will cause the tire to toe out, and destroy the inside edge just like that. First thing I'd do is check the alignment, and afterwards, check your tie rods.

i agree

+1 RWD vehicles will automatically force the front tires apart due to "pushing" from the rear. Just like a FWD car will want to pull the front tires inwards as it travels forward. There should be negative toe on a RWD car when it's sitting still because as it drives it will self correct.
