Sounds to me like an alignment problem or manufacturing one (perhaps they accidentally put the ICE springs on your rears instead of the FFE ones and its riding lower).Kiggulak wrote:So I'm previously a volt owner and used to the electric vehicle quietness and road noise from tires in all electric mode. When driving my FFE I hear an increasingly load sound from the rear tires as I increase my speed. Bouncing between D and L has no impact on the sound so I don't think its related to regen. I've had the vehicle for a little over a year and am embarrassed to have thought this was normal for the FFE just not as well sound isolated with the hatch in the back. However yesterday I got a flat tire on my passenger rear tire and noticed that I've worn through the radials on the inboard side of both my rear tires. Does the FFE with increased battery weight that does not shift with fuel load naturally ride different or is this my Certified Used Focus coming with an alignment problem that used up my tires while I thought the sound was normal.
A symptom. You're the first on here with this sort of issue thus I'm suspecting that it is an anomaly.Kiggulak wrote:Is the rear tire sound thing normal or a symptom?
I think that's from the sheer torque of the electric motor. I find pretty much every morning when I take off out of my driveway and the wheels are turned I spin the inside tire. Or any time it has rained and I start from a stop I spin the tires on the white road paint.davideos wrote:I've had my car for 5 years now and the tire wear on this car has been the most even than any car I've owned. Although the front tires wear faster than any other car I've owned, the inbound and outbound sides on the front and rear tires are even...such that the tires are flat across the top.
Take it in for an alignment. Hopefully it is adjustable.
Look in the owner's manual: 10,000 miles or annually.Kiggulak wrote:The local dealership says tire rotation every 6K miles I bought the car used with 26K miles and now have 39K miles. I took it in for service twice. Once for the LTE modem upgrade and once for a dying 12V battery due to SSN and relay clicks. Neither time did the dealer "recommend" tire rotation despite meeting the 6K miles each time. So what dealers recommend versus what Ford recommends may vary. I like that the dealer doesn't push unneeded services on me but not offering needed/recommended services is equally concerning. South Florida is not know to be battery or tire friendly.
