Tires wearing on the outside edge is typically indicative of a toe adjustment that is out of specification....However the 18" tires on the EX are notoriously noisy tires.fax1 wrote:I have a 2010 EX35 AWD Journey purchased new in April 10 with the 18" wheel package, vehicle has 8500 miles on it. I've noticed that all of tires at 5000 were starting to feather out on the outside of the tread. I rotate the tires at 6000. It is getting worse. I can actually hear them whining at speeds from 10 to 25 MPH. The tires are Dunlops. I can feel & see the uneven wear. Anybody else have this issue? If so was taking it back to the dealer a waste of time? Thank you.
The manual does detail a front to rear rotation at an every other oil change interval but even with the best maintenance these tires can become noisy even with perfect maintenance.
If I were you I would start with getting an alignment covered under your 12/12 adjustments warranty. This will not reduce or resolve the wear that had already occurred to these tires but it might help curb future wear. Although in all honesty they really only get a a certain point and stay that way for the remainder of the tread life.
The best advise I can give you is to get your EX aligned yearly and rotate the tires in a X pattern. The most important thing is to change the direction of the tires that are being rotated FROM the front. This is something we have been doing for years to try to counter this type of wear.
I see this type of wear fairly frequently in lower grade tires and tires with large tread blocks on the edges of the tread.
These are the OE Dunlops
You can see on the right side of the image the outside edge has modestly large tread blocks. Using the image below picture the vehicle traveling along the black lines, as speed increased the wheels start to move toward the toe out side this causes the front wheels to alter the contact surface with the road increasing heat and wear on the front tires. This is a natural habit in all vehicles. Most of the time there is no resulting wear but the combination of suspension geometry and weight distribution in the EX make it able to trash a set of tire in a few thousand miles.

That is what you need.
Note the difference in tread pattern.
