107k and need 5th set of tires...WHY

[Hammerle9]

I replaced my rear shocks about 90k. I then had new tires and alignment done.

I rotated the tires about 10k later. Forgot to do it at 5k. Miles are mostly highway and we don't drive it like a racecar.

Today I pulled rear tires off to check suspension and bushings and everything seems seems to be fine. I noticed the driver side seems to have a little more wear on the inside. I attached a picture of it.

 

Any suggestions?

Thank you

I don't have an answer for you except to say that the tire wear in the photo shouldn't happen at 17K miles unless something was really "off". To me, It looks like the wheel alignment is way off. i suggest you get the wheels aligned and look at the report of how much they were off.

I'd definitely have the alignment checked ... and a tracking check (some call it a 4-heel alignment). Those tires are just plain worn wrong.

From the picture that looks like a lot more (severe) wear on the inside.

Tires should last 50-60 K miles on these cars. Did you buy the car new? Go to a different alignment shop.

I rotated every 5000 miles and drove gently. Always had even wear on all four tires but needed to replace the Michelin's at 44,000 miles. They would have been unsafe (especially in snow northern climates) at 50-60K miles. I believe MWR's (and many others) experience is similar. Your posts are to often stated as absolutes, over the top and sometimes you have no idea what you are talking about like when you tried to tell us that the transmission has no transmission fluid in it.

I'm just about to hit 50K and I still have original tires. I have an appointment for 50K service this week and I'm sure they will tell it is is time to start thinking about replacing. We shall see.

Yes, the transmissions use a transmission fluid instead of a gear oil, sorry. The title of the thread is: 107K and need 5th set of tires-why? That is definitely not normal.

Agree that it is not normal and I stated that in my post #4. My response above to you was in regards to your statement "tires should last 50-60K on these cars" and you know that. Very few of these OEM tires on our FFHs provide a safe service life of 50-60K miles. This is especially true if you drive in frequent rain (like your Naples) or snow/ice of northern states.

 

Here is an informative article from Consumer Reports that discusses this issue:

Looking at your picture you aren't wearing as much in the center as the edges. I find 50 psi is the right tire pressure to get even wear. I got 64k mi. and 60k mi. on first and second set of tires. Second set wasn't worn out yet but I was going on long trip in the snow and didn't want to take any chances. I have 62k mi. on third and should get 80k mi. out of them. I currently have 186k miles on my CMAX. :)

My local shop who installed the last set of tires, checked the suspension parts and all seems fine. They are offering to take it to a frame/alignment shop to double check his work, at no cost to me. :love_shower:

I will let you know what they say. They are doing it on Monday.

[Hammerle9]

Thrust angle was out? Does this seem reasonable?

He said he has an older alignment machine that does not measure thrust. He took it to another place and said it was out.

If thrust angle was out, how does this happen and is this normal?

 

Thank you

[Waldo]

What that means is when they did the alignment, they had the whole car slightly sideways on the rack. Or in other words, both of the rear wheels were pointing equally to the left or right, but not straight.

[lolder]

You didn't answer whether you obtained the car new? If not, maybe something happened to it before.

[Hammerle9]

Sorry. We did buy it new. Never wrecked.

I cross rotated my tires yesterday and this is what they look like with 63k mi. on them. About 6/32" outside and 5/32" inside. Center was about 5.5/32", went through some rain storms last week and they did fine. I don't think I will have any trouble getting 80K im. on this set. BTW It looks like FFH wears more on the inside than outside just like CMAX and I been using 50 psi in the tires for 170K miles and many CMAX Owners are doing this. :) IMO if you had used 50psi in your tires you could gotten 10K miles more looking at your tire wear.

We got over 60k on the stock tires. They just became undesirable in snow and slush. Replaced with Goodyear Eagle F1 A/Ss. No difference in mpg. Massive improvement in traction. Never, ever, rotated tires.

 

Pretty much not diggin' Paul's ideas. I think cross rotating it a serious no-no, as is 50 psi. Perhaps there is some benefit at the risk of DEATH. I'll chill, not rotate, and use the factory psi.

 

The tire wear I see above has to be an alignment issue. Not an expert, but that is not normal on any modern car. Don't blame the tires, psi, or rotation. Something with the alignment is wrong.

Never, ever, rotated tires. You didn't say what your Stock Tires were, but All the Tire Testing I have seen has agreed that Michelin Energy Saver is the best MPG Tire available. Any other tire is going to be less MPG's. https://www.tirerack.com/videos/index.jsp?video=45&tab=Tires

 

Pretty much not diggin' Paul's ideas. I think cross rotating it a serious no-no, as is 50 psi. Perhaps there is some benefit at the risk of DEATH. I'll chill, not rotate, and use the factory psi. This is unfortunately Misinformation. Michelin E/S 93V are rated for 51psi Max Cold and the bursting pressure is around 200psi, no safety risk here. I talked to a Michelin Factory Rep. and explained I was running 50 psi and getting even tire wear. He said they would recommend using 50psi if I was getting even tire wear so I'm going with Michelin's recommendation. :) As you can see below FORD recommends Cross rotating tires from FFH Manual.

 

The tire wear I see above has to be an alignment issue. Not an expert, but that is not normal on any modern car. Don't blame the tires, psi, or rotation. Something with the alignment is wrong. More Miss Information Here, Tire pressure and rotation makes a big effect on tire wear as well as alignment. Using my strategy I'm going to get atleast 80k miles out of my Michelin's so extending the life of the tires is worth 30% of the cost of the tires which is a lot money on expensive tires. :)

From FFH owners Manual: Tire Rotation

Note: If your tires show uneven wear ask an authorized dealer to check for and correct any wheel misalignment, tire imbalance or mechanical problem involved before tire rotation.

Note: Your vehicle may be equipped with a dissimilar spare wheel and tire assembly. A dissimilar spare wheel and tire assembly is defined as a spare wheel and tire assembly that is different in brand, size or appearance from the road tires and wheels. If you have a dissimilar spare wheel and tire assembly it is intended for temporary use only and should not be used in a tire rotation.

Note: After having your tires rotated, inflation pressure must be checked and adjusted to the vehicle requirements.

Rotating your tires at the recommended interval (as indicated in the Scheduled Maintenance chapter) will help your tires wear more evenly, providing better tire performance and longer tire life.

Unless your tires are directional tires (e.g. Goodyear Assurance TripleTred) that are designed to rotate in only one direction, then both the tire manufactures and the auto manufactures recommend rotating those tires as PT showed above. It is important to get them rotating in the opposite direction for maximum service life. Neglecting to properly rotate them can result in noisy tires that make a thump-thump-thump sound at higher speeds.

[Cobra348]

Add Goodyear Ultragrip WRT Ice tires to the directional tread list. I use those during the Winter. Expensive but damn good in the snow and ice.
