Tire wear issue
2013 c300 40k miles stock tires.
has anyone seen this type of wear? What can be an issue? I did an alignment in april at the firestone and now thats what has happened to my tire. I was doing a plug because of nail and knoticed that tire tred shifted i guess towards the outside of the car and the insed is ripped in some parts of the tire but air is not leaking, i can feel metal wires when i lift some of the ripped rubber.
Original continental tires on original 17 rims

^It's hard to see in this picture, but it appears to me your tires are underinflated. Why?
It seems both the inner and outer sides of the tire suffer a bit more wear than the middle. Now, it might very well be fine PSI wise, but that's my first guess. On any other car if you see excessive wear in the middle, the tires are overinflated, and if you see excessive wear on the outer shoulders, the tires are underinflated.
On a W204, it's a crapshoot.

Yeah Ok then this is above my paygrade. Your tire pressures look fine - so perhaps it could be the shocks but I can't explain why your alignment appears to be perfect then - how often do you do an alignment?

Just wondered whether you are hard on tyres? Heavy cornering?
Are you driving on harsh, lose or steep surfaces?
My OEM Bridgestones failed similarly. I took it to be a poor quality tyre. The next set Mitchelin Primacy held up well.

My Michelin Primacys have fared well (or extremely well given the feedback on this thread). However, I only see the outer shoulder of the tire being a bit more worn than the rest (just like every car I've owned because this Penguin likes to drive HARD
). The inner shoulder of all 4 tires don't have any pronounced/excessive wear.Curious - did your Bridgestones have excessive inner tire wear as well?

i actually dont do heavy cornering at all, i drive in boston and roads suck here but i do avoid every potholes and bumps a lot. I want to kill this tyres before getting mitchelin sports. Rear tyres are just like new. Do you know by any chance if i can keep continental tyres in the back and put mitchelin on front? Rims are staggered.

i did alignment one time this year in february and one in november last year.. i think it shoks as well because i cant stick two fingers vertically in between tire and fender.

Not worth saving the few hundred dollars.

im going to try the same, roads suck here tho, i want to see how it will drive. Its not going to explode when driving right? As you can see in the picture my tire is ripped a little.

So to answer your question, no, it won't explode and yes it'll be fine.

OP...to me it seems like your biggest problem is the overall age of the tire, and in my experience, the primary cause of tread separation is dry/brittle/old tires. The "general" shelf life of a tire is around 6 years, but depending on environmental conditions and how they are stored, this value varies. You may have a 2013, but keep in mind your tires may have been manufactured before that year.
This leads me to a conversation I had with another enthusiast, in that while some tires tote very high wear values (UTQG), depending on the driver, the tire may expire well before they reach the wear bars. In these scenarios, it would have benefited the driver more by going with a lower wear rating tire and an overall increase of grip. You basically want to find a balance of age vs treadwear.
If I was in your shoes, I would replace those tires...or at the very minimum avoid doing any high speed runs in fear of a blowout.
Also, keep in mind as the tire ages, the compound also changes (regardless of wear). So if you are used to cornering a spot at a certain speed, don't expect the same tires to behave the same 5 years later even though the amount of tread is the same.
FYI, I'm currently on Michelin Pilot Super Sports and have been on them since I replaced the OEM set at 30k miles. I have 80k now and to be honest, I'd never go back, but I do live in CA and my car never sees snow. BUT...seeing as you are in a 4-matic, I'd look into the AS3+ instead.

I am not sure what your experience in tires is but I can 100% assure you that you will not die if you mix two brands as long as they are the proper size, speed & load rating, compound type (summer, AS, Summer etc) and on the same axle.
I work in the auto industry for someone that installs 4 Million yes, 4 Million tires a year on cars. Is it ideal, of course not. Could you damage your car, unlikely, die? Not unless you put two summer tires and two winter tires and then decide to go driving in heavy snow or you decide to put all seasons up front and high performance Z rated or higher tires on your hi-po car and then go over 150 miles an hour . Two compatible all season tires of the appropriate size on the same axle by two different manufacturers should not be an issue. Just adding some clarity to the topic

I agree saying one will die mixing tires is extreme but I'm dead against mixing tires because of one thing in particular. You can match speed rating/load index, maybe match general compound type at best or what not. But... Every tire has different handling characteristics, every tire behaves differently even if small and that can cause a accident vs not having one. Plus, tire manufacturers do not tell the general public their tire compound makeup and structure so ur just guessing.
You want all 4 tires to be the same.
Now if you want to live on the edge, sure, mix and match tires, heck have 4 tires that are all different, go nuts! YOLO, right?
As far as what I would do, no thanks. I don't risk the 4 tiny contact patches on my vehicle.

"This. If you're doodling around town, it's no biggie, but in the off chance you hydroplane driving 70mph when it's 35F out..."
If you are hydroplaning your tires are not making ANY contact with the road, so at that point what difference would it make what tires you have on?
Yes, I am only kidding.....couldn't resist. Sorry.

Guys,
As I said it is not ideal and not something I would do, just wanted to add clarity on the you will die comment.
Alfa,
Technically you are correct. If you are hydro planing, the tires won't make a difference since none of them are making contact, but to Penguin's point, once they do make contact, different tires will behave differently which will affect how the vehicle handles coming back in contact with the pavement.
Clearly, 4 matched tires (including staggered fitments) replaced at the same time is ideal for all situations but unless you get in a situation like the 4 wheel hydroplane no one should die.

Some tires are more effective at resisting hydroplaning, and some tires are worse. The worst case scenario is this case is either
All 4 tires hydroplane and 2 tires end up grabbing traction first
Or all 4 tires hydroplane and none end up grabbing traction until it's too late.
If all 4 tires hydroplane and they all end up getting traction at some point but at different points, that can also be a problem.
Anyways, the point here is
Is it worth a $300 savings or $500 savings and be screwed in the off chance in an emergency scenario? Well, that's up to each person.
I also buy insurance. I'm worried about a rainy day. I also understand some choose to live on the edge...so...there is that. To each their own.
