Best Tire for the Mach E?

[Mach1E]

So are you saying you charge to 100% every time? Just curious. I have no need for full range - I rarely see my battery drop below 70%, from a 90% starting point. But, when I have needed it, I simply charge to 100% beforehand.

Nah, I say charge whatever you need and don’t worry about it.

There are downsides to charging to 100%
all the time- it takes longer, it’s less efficient, and the car is less efficient (no regen at 100%).

But the whole “dont charge to 100% out of degradation fear” argument seems silly for the reason listed above.

Interesting that the tire discussion turned into a charging discussion. Everything I have read says there are two things that will extend the life of a lithium ion battery. #1 charge it daily, #2 don't charge over 90 percent daily

I am one of those people who doesn't routinely charge his phone to 100%. I charge to 80% most of the time. I'm never far from a charger. And then when I travel or otherwise know I may not be near a charger, I go to 100% Here's the logic - it preserves the battery, maybe only a tad, but 6 months in my phone's battery health is still 100%. So, when I need full capacity, I'm truly getting full capacity, not a slightly diminished capacity because (for my needs) I was needlessly charging to 100% all the time. To each his own - everybody's needs vary.

Phones are getting smarter about this. iPhones have an optimized charging setting that charges to 80% immediately when plugged in and stops there. Then it resumes charging to 100% based on what time you start your day and unplug the phone, so that the SOC time spent at 100% is minimized.

To be clear, I did not recommend never charging to 100%. The car is designed to be charged to 100%, and I do it regularly when I am getting ready to go out of town. Every time, actually. I want 100% of the possible range as I leave my house and go out into the public charging jungle.

But if you don't need all the battery, it is a good practice for maximum battery heath to follow Ford's recommendation and charge to 90%, unless you need more for a specific reason. Like I do when going into the office.

I have my phone set to charge to 85%. I was at an all day conference last week and I arrived back at the hotel at 9 PM with still 50% of my battery remaining. That would have been a good day to charge the phone to 100% but actually forgot to do it. And it was just fine.

FWIW, I agree on what to do, for the same reasons.

Just pointing out the irony of using less battery for fear of having less battery.

People do this all the time though. Not much different than people who die with tons of money leftover because they lived their lives being afraid of running out of money.

It’s all about balance.

On the topic of tires- I absolutely love the PS4S tires I just put on. They ride better, handle better and have much better traction than the stock GTPE summer tires.

And despite what some believe- softer summer tires actually tend to have lower rolling resistance.

“
In fact, according to the Tire and Rubber Association of Canada (TRAC), modern improvements in summer tire tread patterns, rubber compound formulations, and constructions can lower rolling resistance by 10-20%, which can earn you a 2-4% improvement in fuel economy without any extra effort.”

Getting back to the original discussion, has anyone mounted Hankook Ions yet? They are number one on my radar unless I start reading horror stories.

Has anyone else experienced what @rhougey has experienced with the Hankook ION EVO AS SUV tires, a 5-10% loss of range at highway speeds as mentioned in a post back in February?

I need new tires too and had planned to get the same OEM Michelin Primacy A/S, but the Hankook tires look interesting, except that I only want them if they do not negatively impact the range.

I have had them on for about a month. Very quiet, comfortable tires. Not as sticky as the OEM GT tires, though, so if aggressive driving performance is what you are looking for, these are not the right tires.

I am not experiencing any loss of range. In fact, I think they are more efficient than the stock GT tires. I am still taking data to determine if that is accurate, but definitely I have not lost any range.

Thank you. Quieter than OEM is what I am looking for. And my aggressive driving days are 50 years in the rear view mirror!

Good to know. But I am coming from the Premium trim that has Michelin Primacy A/S tires.

It's possible that both are true: they are more efficient than the stock GT trim tires and they are less efficient than the Premium trim tires.

I've had Hankook Ion Evo AS SUV for about 8 months now. Really like them. Quieter and smoother than the factory Michelins.

I had installed red pucks on the jack points before taking the car in to Americas Tire/Discount Tire. I walked out to their shop and told the techs the jack points are in red and then watched to make sure they lifted it at the right spot. They had 4 guys working on it at the same time. the whole process took about 15 minutes (to replace all 4 tires).

The best tire is dependent on your criteria. I wanted lots of performance and decent tread life. That led me to all-season 275 UHPs. That led me to 9-1/2” rims. My daily commute sucks down roughly 10%-12% of my battery (round trip), so I care not a bit about range. Everyone has their own criteria. ??

I went +1 width with 245 Conti dws06+
... maybe some some (5% ?) hit on range, but better performance wet and dry than stock Michelin on my Select

It's possible that both are true: they are more efficient than the stock GT trim tires and they are less efficient than the Premium trim tires.

I think it is possible that both are true. The GT spec tires are mst likely not as efficient as the Primacy A/S tires that came on the Premium model like yours and mine. And I think it likely also that the range reduction may not be as pronounced or as noticeable for people who do not do long range driving exclusively as I do. But my analysis has not changed. I’m still having to stop for power more often than I used to when I drive from one home to the other. I prefer not to stop.

I really appreciate your effort to analyze and share. It has made me decide to keep the Primacy A/S for now.
