My mechanic, who was a Toyota mechanic for 20 years before he opened his own shop, told me the cupping wear is not camber, alignment or any other mechanical issue. He said any of that will not really solve the problem, Toyota is very much aware of the issue and won't do a thing about it. I'm getting ready to change the rims on my Matrix 2005 with the hopes it will finally solve the problem, if not I give up.

Changing the rims is NOT going to fix the problem.
If your mechanic friend doesn't think it's alignment, what did he think it was? I'm sorry to say, but I think he is totally wrong. Most irregular tire wear issues can be traced to alignment problems of some sort - and in this case, it is clearly the camber. As peter reported, he seems to have solved the problem by fixing the camber.

I got a great belly laugh off your arrogance and hope it works for you. I have every service record of this car since it left the lot, one of it's first, under warranty returns was tire wear. After seeing people ripped off by the dealership and other shops, my new mechanic, who I venture to say has way more experience than you or any single car owner and has indicated to me Toyota is very much aware of this problem and who, by the way at the dealerships where he worked has also, been assigned to charged many a camber, struts, alignments, etcetera only to have the problem exist, he is a decent, honest mechanic. So, check the year and model Toyota changed the rims on these cars after you 'fix' your car. And, he didn't suggest changing the rims, it's my idea.

I have researched this issue since I've had this car, I love the way people who don't really know what the issue is throw out all these suggestions and especially cracks me up when you talk alignment. I wonder if you understand this is a factory issue that Toyota is not acknowledging as a defect just like they didn't acknowledge the issue of acceleration. In one of the first post, the dealership suggest "his wife turns too much". That should be your 'duh' moment. For people who use this forum for what it is suppose to be, real issue is not alignment, cambers, struts and all the other expensive repairs being suggested (unless it started happening after years of not happening). There is an issue, my last attempt is to try new rims because Toyota changed the factory rims on these cars the same time the problems started. By the way, if you google Toyota, unever wear cupping you will get a huge return on the issue, people who have had this problem since they drove off the lot, fully warranted and have spent years without a decent fix. That means they have realigned to factory specs and tried other versions, they have changed struts, replaced cambor screws and every other speculation and nothing has worked. So there are lemons, not every single Toyota being driven has accelerated unexpectedly, so please don't mention that "i've never had the problem, must be your ......" Toyota knows it and just like the gas pedal/floor mat bs, they aren't gonna fix the cars.

I'm sorry, but perhaps it would be good to explain where I am coming from. I am a tire engineer - many years at that (more than your mechanic!)
You've highlighted all the things you think are NOT the problem, but you are still fishing for the solution. The problem is the alignment SPEC. The spec issued by Toyota calls for camber anywhere between +0.2° to -1.3°. It's the large negative number that is the problem.
As proof I offer 2 posts: Rocky's Message #70 and Tamedskr's Message # 185.
They seem to be the only ones who had the problem and fixed it - and they both did it by adjusting the camber.
BTW, I have documented other vehicles that seem to have a similar problem - and guess what? Camber!
As you have pointed out, it's Toyota's problem and it's their alignment specs!

Sorry, we tried the camber 'fix' and it doesn't work over the long haul. Seriously, if it were just the camber don't you think Toyota would fix it?

The camber is set so the car won't roll over doing the "slolam" driving test through the cones. The car-all four wheels- is set up like the right front of a super-modified race car for a 1/2 mile oval. When the car has to pass the slolam test it will roll over if the tires are not "canted" so more rubber is on the road during maneuvers with high side loads. That is why the dealer will NOT deviate from the recommended camber settings. Even though the tires will wear out prematurely, they won't ever solve this problem with the Matrix. The runaway car problem has them scurrying enough.
Seriously, if Toyota, Ford, Honda, GM or whomever has to admit to a problem they will all play dumb and talk the party line. Seriously, I am absolutely positive Toyota or any other car, truck or motorcycle maker will do anything to save their own skin. Seriously, I am sure Toyota will spend billions to make the public think they are very concerned about safety. Even though the problem might just cost millions to fix. A hard fix is out of the question. A couple million tons of BS poured on top of the problem is how this is fixed. Just think if no one would speak up for the victims of the runaway cars. If there were no ambulance chasing lawyers they would just shove the problem down our throats forever with their fingers crossed behind their backs. I will never buy another Toyota.

Did you replace the tires? Once tires have developed irregular wear, they are exceedingly difficult to get the irregular wear replaced with something else. You need to start over to get a good reading!
#253 of 265 My own two cents on the Matrix tire issue.
Nov 08, 2010 (3:49 pm)
My 2005 Matrix, purchased new in 2005, shares this problem. The original tires were spent at about 31000 miles in the third year. The dealer had the same line that these stock Continental tires just don't last. The car has been reliable overall, so I didn't give it much more of a thought.
I purchased a pretty expensive set of Sumitomo tires to replace the originals. In the past couple of years, I have rotated the tires on every oil change at about three thousand miles each. Every time, when the rear tires come forward, they're out of balance. I have them balanced of course, but this tells me that wear is taking place.
Seems most posters complain about front tire wear, but mine seems to happen when they're on the rear.
I took my car into the dealer when the thumping noise began around 31K. They confirmed it was the tires. To their credit, they suggested the tire store down the street, as the prices were better.
Every rotation of the new tire set each oil change results in vibration through the steering wheel. This means of course means the tires are wearing unevenly. The local tire shop in our new home town says this is abnormal. The dealer I bought the car from has never heard of this complaint. He suggested that I call Toyota, and the rep had also never heard of my problem. I will add that the Toyota company rep insisted on calling my car a Corolla. Yea, I know it's based on the corolla platform, but that was just annoying. He also had the mind bending habit of saying "uh huh" before I could finish a sentence. He seemed to read a canned message, ending with a suggestion was to take it to the dealer.
The only new car I've every owned. Not sure I'd buy another one.

Yep, the dealership will deny, deny, deny just like they did when the acceleration problem occurred. I think a class action lawsuit is in order.
