30k Miles on Premium - Rears are Shot

[GatorGrowl]

The only issue is that we are getting to the winter soon here in the North East and it probably isn't a good idea to run these tires in the winter. Maybe I will try to get some more life out of them and then replace them when winter arrives.

I took another look at the rears and they have a little bit of life left i guess?

That looks like either too much positive camber or low tire pressure. You have much more wear on the outside than the inside.
Right now that tire is unsafe when it’s raining. You might get some more time if you move to negative camber, but as is that tire is unsafe in the rain.
I’d replace at least two if not all four (depends on your budget), get a full alignment of all four wheels, and make sure you are religious about keeping them at 39psi/2.7 bar

Definetly not rotating them is the issue. My guess is Ford never did the free rotation when they replaced the junction box and so basically my tires were never rotated.

I have to admit, going easier on the accelerator isn't going to happen, the main reason I bought an electric car is the instantaneous torque, love it

I hate to replace these fronts because they look like they have a ton of life left but if its really that big of a deal to do all 4 I guess I will just do it. Should I consider other types of tires or just go with the OEM tires?

There are better tires out there - I’ve been eyeballing the kind with noise reduction. At 39psi every bump sounds like a basketball. NR tires add sound deadening material inside the tire. Don’t know if it works, but I like the idea.
You can replace only two, IMHO. Only reason to do four is convenience, to reduce shop visits. My Ford dealer comes to my home to rotate the tires - $26. I drive up to 200 miles a day, so I’m pretty religious about tire pressure and rotation.
TBH, I’m probably too hard on the accelerator too. I tell myself not to be - but yea, all that torque is just too fun. ?

Over the years I've replaced different brands with Michelins, and every time its been a noticable upgrade.

I'm torn between cross climates (ralley) and pilot sport 4-AS (GT). When the day comes, hopefully I'll have this decided.

Yes that is my observation as well, def worn more on the outside. Oddly the right front which I didnt take a picture of, looks more worn than the left front which is the picture I supplied.

Sorry i mean cross climate 2! not cross country 2.

I just want to know why Ford hasn’t put a ‘24 in your hands to test the HVBJB with the new rear motor and extended limit. ?‍?

As you know, they had me run my loops with a data tracker so they could see the conditions and loads I was putting the MME through to blow the units. I am sure they used that data to probably both upgrade the HVBJB and/or install software that limits the voltage/amps going through the box to prevent this from happening in the future. Shortly after turning the MME back to Ford, I saw Ford manufacture testing EV's in the areas I drive, and I am sure that was not a coincidence .

If you've got 30K on the tires, I would recommend doing all 4 and yes I would do an alignment, it's a small price to pay to insure that your car is riding correctly.

I don’t understand why get an alignment? If existing tires wear unevenly sure. Also my local dealership checks the alignment when I drive into the service bay. Why would changing the tires require an alignment?

America's/Discount Tire offers free rotation/rebalancing every 5k mi if you buy the tires there or you can get the same deal by paying $100 on your OEM tires (IIRC).

since your fronts look pretty good with lots of depth.... you *could* probably get away with 2 new on the back. Drive with them on the rear for 10k miles, and then start rotating front to back every 5k.

I really like the Continental dws06+ for all-season.

With AWD its typical that you replace all 4 tires together. If run two new tires on the rear and two old tires on the front they will rotate at different rates. It will force the differential to work overtime and shorten its lifespan. EV's don't have diffs but the computer will have to sort out the the different RPM's and Ford is probably not going to recommend it.

the tread on the front is 'nearly new' by the looks of it. probably almost no difference in effective diameter.... at least not any more than he's been driving with by not rotating.

Yeah, but it's still not the same as the real thing. GOtta have that HeIsNuts seal of approval. ??

Does it though? First, $30 is probably low. Second, most places recommend rotating every 3-5k miles lol. And some people here actually do that.

But let’s go with your $30, and let’s say you rotate your tires 8 times to extend your tire life from 45k to 60k, and a set of tires runs you $800. I’m being extremely generous toward your position with all these numbers. Tire rotation probably costs a bit more than that, and probably doesn’t extend the life by 15,000. But just for argument’s sake.

That’s $1,040 for 60k miles = 1.73 cents per mile, and $800 for 45k miles = 1.77 cents per mile. You saved 0.04 cents per mile. $24 over 60k miles. And that’s if your time is worth nothing.

Now raise the price of the tire rotation a bit, or reduce the extended life a bit, and you save nothing at all. Maybe you actually lose money. And again, you’ve definitely lost money - a lot money - if you value your time at all.

Tire rotation is the household recycling of the auto industry: wasted time and effort that accomplishes next to nothing.

I actually pay exactly $29.99 for my tire rotations and have had them completed almost exactly every 10,000 miles (4 times since I took delivery of my Mach-E). These are my actual tread depth measurements the last time I measured them in August (OEM tires):

08/22/24
41,995 miles
Front: 5/32 (both sides)
Rear: 5/32 (both sides)

All that I can say is it has worked for me. I have even tread wear, after 41,995 miles, for a total of $119.96 for 4 tire rotations (far less than the amount you estimated for an unnecessary number of rotations). The current price to replace my tires with the same Michelins would run $263 each (plus tax) at Discount Tire--far more than the $800 you estimated for 4 new tires. When I do replace my tires (probably at Discount Tire), they give you free tire rotations for the life of the tires purchased from them, so I will only be spending "my time". Even then, Discount Tire is only 10 minutes away from my house and experience has shown me that I can get rotations completed there in less than an hour.

I think you answered your own question: "I don’t understand why get an alignment? If existing tires wear unevenly sure."

You get an alignment to help insure against uneven wear. Also, your alignment can change at any time. When you get new tires, your circumference changes, any curb rub, pot hole, mileage, effects your alignment. An alignment insures everything is wearing evenly for $100-$200 it inexpensive to do and is a small payment when you consider what your spending on a set of tires.

New cars are notorious for being out of alignment from the factory. Every car owner should get an alignment. A little extra negative camber would probably be the easiest way to make the Mach E handle better anyway.

Higher mileage tires last longer

I will admit, I wasn't properly rotating the tires. They were only rotated once (maybe) when Ford fixed my battery junction box (at least they promised to do it gratis).

My fronts still have a good amount of life on them but the rears are down to the wear bar.

Can I get away with just throwing 2 new Primacys on the rear and then either keeping the rears and fronts as a 2 tire set or even just not rotating again and let the rearrs wear down to maybe catch up to the fronts (probably wont happen, I would guess fronts have 10k left).

Also, I have been reading the threads about people liking other tires like the Hancook Ions and the Michellin CC's. I assume it wouldnt be great to get 2 new tires in the rear only and not match them to the front?

Lastly, since I am just doing 2 rears, can I avoid the alignment that everyone seems to recommend when you get a set of new tires?

THANKS

High mileage tires aren't as grippy so keep driving hard and see what happens. Ride, traction, braking? Something will show up.

My AWD Select tires lasted 32k miles and all 4 were bald, I also enjoy the torque! For me its been 8 years of driving an EV and the only maintenance has been tires, so i keep enjoying the fun and chalk that up to my only cost. I also replaced with the Hancooks, same range, and overall I like the tires a bit more than the factory ones.
