Just a reminder that when you rotate your tires(5-10k mi) do it in a X pattern, Right front to left rear, left front to right rear so direction of rotation is reversed every time you rotate the times.

This will minimize the noise issue. :)

Actually, the manual (2013 anyway) says to rotate:

  • front straight to back
  • back to front crossing

This will move each tire to every location as well as change direction of rotation.  Be sure to do it the same way each time.  My second set is just shy of 70k miles with, I hope, about another 10k to go.

IMO the tire noise is caused by the high negative rear camber causing inside tire wear and feathering.  When driving in a straight line, negative camber will increase tire wear on the inside edge of the tire.  High negative camber benefits cornering when driving agressively.  There is no rear camber adjustment on the C-Max.  I would say about 80% of our driving is high speed at 70+ mph.   So, I believe the inside rear edges are scuffing / feathering perhaps more than "normal" driving driving at lower speeds. 

 

Tire rotation doesn't prevent this but may mitigate the onset of the noise and miles until the noise is unbearable.  One would have to dismount the tire and reverse it on the rims to perhaps wear the edges more evenly and thus keep the noise at an acceptable level.  When one adds cost to the equation, it is not cost effective to dismount 4 tires, reverse mount and balance them every 5-10k miles to maybe squeeze out another 10k miles.

After getting 64k and 60k mi. on my first and second sets of tires and only 1/32" difference between inside and outside of Michelin Energy Savers and I could have gotten

another 5+k mi. but was going on Winter trips and wanted the extra tread so I replaced them. The feathering I'm seeing is making the noise and I think can be controlled by reversing the rotation every 5-10k mi. by using the crisscrossing the tires. :)

Perhaps the fact that you run 50+ psi lessens the inside tread wear and feathering.  In addition, my "unbearable" noise is at speeds of 72+ mph.  If I would drive at less than mostly 65 mph and with no 2000 mile cross country trips on the horizon, I could likely live with the noise for many more miles.   

 

Also, I rotated my Michelins myself and did the recommended rotation sequence about every 7500 miles which effectively means the reverse rotation happens every 15 k miles.  So, perhaps crisscrossing every tire rotation would help as that would provide 2X the opportunity to offset the feathering.

P3G, how are the General Altimax RT43 tires wearing?  Are you still happy with them? 

 

My OEM tires on my 2013 CMax SE have 48K miles on them and dealer says the road noise I am hearing is due to uneven wear on all of my OEM tires (even after they just replaced my transmission under warranty for grinding/thumping noise, along with new wheel bearings).

 

Car rides much quieter with new transmission and wheel bearings, but there is still a thumping/rotational road noise in front. I would like to eliminate the tires as a factor in the rotational noises I am still hearing (before I go back to dealer). I'm thinking of replacing OEM's with the General Altimax RT43, and just wanted to get an update from you (and anyone else) who has the Altimax TR43 tires. Thanks.

 

Just an update on above. I replaced all four OEM Michelin tires with the General Altimax RT43, and all thumping/rotational road noise is gone! The car rides as smooth and as quiet as the day I drove it off the dealers lot new.

 

Now for the interesting part...I had the tire installer check alignment, and all measurements were well within manufacturer's specs (including rear camber). I thought for sure it would be out of alignment, given the significant amount of tire/road noise I has hearing (even with rotating my OEM Michelin's every 9K miles and running them at about 45 PSI). My guess is that all the miles I had driven with bad transmission and/or wheel bearings contributed to the abnormal tire wear.

 

On this new set, I plan to rotate every 5K miles, and make sure they are crossed as recommended in Owners Manuals.

What was the rear camber?  IIRC, the spec allows camber to be -2.4 degrees.  Many performance cars will not have near that much negative rear camber.  The closer one gets to zero, the less inside wear one will have on the tires. One member put a kit on to reduce their negative camber.  IIRC, when I was researching camber, the Prius spec was less than -1.5 degrees.

 

I believe the high C-Max negative camber is for the rear of the C-Max to handle better given the extra weight of the HVB over the rear wheels. But tire noise is the tradeoff.

Yes, the rear camber spec range is -0.9 to -2.4 degrees. I agree that -2.4 degrees seems high. (Updated post: Attached alignment results and specs):

Let us know what your MPG's are. :) Paul

 

My current Year-to-Date MPG is 45.1 MPG (and most of that was with bad front wheel bearings and transmission). Also, keep in mind us "Northerners" take an MPG hit due to temperature, which was 13F this morning :(

 

I fully expect to take an FE hit of about 5% with the General Altimax RT43 tires, but I only drive about 12K miles a year, so it is not as big a hit for me as it would be for someone who drives many more miles. I'm OK losing 5% FE for an increase in driving comfort and better handling in the snow (which I'm afraid is not far off).

Here's my alignment when I put on the RT43s showing -1.9 and -1.7.   My previous alignment had camber at -2.0. and -1.8 IIRC.

Here is one of mine.

alignment
 
I got my New Lug Nuts so I flipped tires side to side to reverse the rotation after Dealer did front to back.  Even with 50 psi in my tires the center has more rubber than the outside which has a little more than the inside. :headscratch:

Here's the results of my first alignment; -2.3 / -1.9 for rear camber.  See rest of the topic to read about putting on adjustable arms.  My latest alignment in Sept 2016 had the rear camber at -0.6 / -0.9.  My second set of Michelins are now just shy of 70k miles and have worn much better.  There is still some inside edge wear but nothing like before.  For the new tires I think I'll have the right side brought to -0.6.  Any real danger in pushing the camber too close to zero??  I don't see why a car should insist on wearing off the inside edges.  Good grief, this is the 21st century!

Did you notice any improvement in mpg's being able to adjust down the camber? :)

I have 58k on the OEMS and it's time, wear indicators are level with the tread.

My 2 cents re the V rating/ie; 100 MPH+; coming back from Vegas I had to get my wife to Firestone to pick up her car before like 4-5 o'clock, and so I probably AVERAGED a hundred miles an hour over the course of 4 to 5 hours, with speeds maxing out at 120-140mph... I have done the math and the extra couple hundred dollars a year I would spend to drive the car in a fun way is worth it to me...
 

 

You, Sir, are a disreputable person, a cad and a bounder! To have the temerity to drive a "slow car" fast? And, hey, can your C-Max (or mine) really do 140? You may be my only chance to know. And thank you for the most entertaining, contrary and over-the-top response I've ever read on this forum! Nice to hear that the C-Max can please other kinds of folks, for whatever reason.

I put Michelin X-ice Xi3 winter tires on my C-max last Friday, using the factory rims.  OEM tires from 2013 were down to 3/32 to 4/32 tread left.

I bought size 215/60R17.  These are 1.2" larger diameter than the OEMs.  That raises the car .6".  I don't believe it could take larger diam tires, but please post if you have run this size or larger on your C-max.

 

For some reason at the time I was looking the 215/60R17 size was cheaper than any other 17 inch X-ice: $113.50 at Amazon or Walmart.  The Ford dealer was quoting me $180 for the same tire in OEM size.  I ordered the tires from Amazon, a first for me.  They appeared neatly stacked on my front porch a week later.  Cost was reduced by a $15 "first time Amazon tire order" offer that appeared on the Amazon page for the tires, and 5% back for using an Amazon credit cost, so net was about $104 a tire shipped (plus tax).

Local mounting and balancing cost $62.50.  The 4 tires (two on rear seat, two in way back) pretty much filled up the car on the way to local shop.

 

So far they are pleasantly quieter than the well-worm OEM tires.  Ride is softer.  OK in first snow here end of last week.  Curious what the mpg hit will be. I haven't had winter tires on the C-max before so I am looking forward to improved and safer winter driving this year. 

Very interesting! Did you have any clearance issues with bumps or tight turns? You make me wish I'd done this, but I just picked up new wheels and snows today in the standard size.

No, I took a quick look at my spreadsheet for several months before and after - can't see any difference.

My Michelin tire noise is more annoying at 20mph than 65-70mph and I'm running 50 psi. :)

No problems so far, knock on wood(-grained plastic laminate).   It is a pretty stiff suspension so wheels don't bounce around a lot.

Worse case scenario is probably hitting a bump during a sharp turn while hard braking - I'll try to avoid that.

Most FWD cars wear out their front tires twice as fast as the rears. Is the C-Max that way? All this talk about rear tire wear/cupping makes me wonder.

 

I was planning a strategy that embraces uneven tire wear. My daughter's C-Max Hybrid was bought used with a mismatched set, two Kumho performance tires and two Michelin OEMs. I plan to buy her a matched set of snow/rain tires and dismount hers for my future use (they have lots of tread). So I could replace two of my Michelins when they get worn. Once I wear out those six Michelins -- in 50K miles or so? -- I could use the Kumhos as half of a summer performance set.
