New tires killed my range (20-30% decrease)

[Fernand]

With all the diffuse expert discussion, you guys know he lives in flat Florida, he doesn't need winter tires, he doesn't care about the best racing handling, he just needs the most efficient on range at a good price.

Whatever else is going on, to be worked out, isn't there a single good recommendation y'all could make on what tires he could go back and trade his set for tomorrow?

Finally replaced the stock 18” Michelins on my SR after 43,000 miles after hitting 2/32. Lifetime consumption over 43k was 218kW/hr.

Got a great deal on the new Michelin Pilot Sport All Season 4 at Costco.

I remember reading that the Model 3 was designed from the tires up. I suspect it's going to be difficult to beat the stock tires.

If you are going up through Atlanta and then north via 575 up through Murphy NC there are Tesla chargers galore at Harrahs casino just north of Murphy. Something like 24 chargers free to use. We drive up to our house in the extreme north GA mountains every few months and I don’t recall any long stretches where there aren’t some chargers.

It's required in Europe. So you can look it up at Euro Tire shops. But it's not always the exact same tire, but often is.

But in any case, people should realize that rolling resistance effect it's huge, large tyres are critical and that you in USA should work to have the labels on tyres with the tyre classes as in EU

I tried to find that information online worldwide, but seems difficult to find. Tyres already have so many confusing encodings, I wonder which one is the rolling resistance one? Any tips where to get a shortlist of tyres for certain size, weight and speed classifications and rolling resistance?

Also I would skip Atlantic station chargers in downtown Atlanta. The one just to west of 575 exit is more reliable.

This is just one example, an arbitrary tire at an arbitrary online shop in Europe. UK shops seem to work best. Partly because they are in English.

I had my favorite euro shops I’d use when looking.

Notice this Tire is rated C for Fuel Pump.

Note the noise rating in Europe is exterior noise not what you hear in the cabin. Not the same thing. Many reviews include cabin noise. I would buy one month of consumer reports just get their tire rating on noise.

differences in tires for same size is not 20%-30% of consumption. theres something else going on.

Yes - this.
I have these same tires and they are amazing. Seeing close to OEM consumption per mile. Last family trip was around 218Wh/m.
Feel the hubs after a drive - are they hot? could have a caliper that is binding.

For those interested, some more background on the type energy labels used in europe https://ec.europa.eu/energy/sites/ener/files/documents/user_guide_-_tyres_en.pdf

From this document they state there is a 9% difference between between G and A. no indication on the step size and if it is lineair.

Went for a 20 mile drive last night, and none of them seemed particularly hot compared to the others (it was raining, so that may have cooled them down even if they were). Verified that brake lights weren't on while driving.

Since I got the car back, it's had a tiny bit of "driving in quicksand" feel to it, but I attributed that to "these are good, grippy tires", since I've never had high quality tires before and didn't know what that would feel like. I'll be taking it back to Costco when they open and ask them to raise it and verify that all four wheels spin freely. If that doesn't do it, I found a local shop that has the OEM tires in stock for an additional $300.

Thanks for all the help! No qualms about taking this trip if I have my normal 200 miles of range, but 160 is cutting it too close for comfort.

Really sorry to hear you're going through this, but it's a learning experience for us all. I'm at the point where I will replace my mxm4 after this winter. I'm probably going to stay with the mxm4.

Keep in mind that 9% is probably based on ICE. On EV I suspect the difference is much larger. Like the difference in driving 65 mph and 80 mph might cost you 25% on EV but only 10% on ICE.

This is the unfortunate reality. I can't put it into maffs, but intuitively it makes sense: Since EVs are so insanely efficient, every stressor has a a far larger impact on them vs. an ICE car.

Any time you change tires you're going to go threw the rolling resistance. It take some time and miles on them to get worn in and your Range will always change. Happens on any vehicle

Point is, if you are in US, there's no way to know which kind of performances to expect, even with the same model code, because you don't have a compulsory labeling system.
This is what consumers should push public administration to do in US.

Update: Wasn’t able to get the tires swapped on time. Pulled out of the house at 100% while it was raining and 15 mins later on the highway I was showing an estimated range of something like 90 miles. Almost turned around.

Decided to keep pushing through, and a few hours later I’m hitting .225Wh/mi, which is basically getting me full range.

Perhaps your bms was thrown off and needs to be recalibrated. 225wh/mi is right to spec.

Good, and rain will easily knock off 5% of range.

 

[Fernand]

Hopefully we'll hear from him again

 

[polyphonic54]

FWIW I made this exact tire change.... lifetime on the MXM4s (bit north of 20k miles) was ~263 wh/mi

After about 1500 miles on the Pilot Sport All Season 4 I'm at about ~284 wh/mi

An increase in consumption of about 8%.

I had virtually the exact same numbers +/- 5 wh/m. The PS A/S 4 was tested over 2000 miles, AND I drove it harder with the new tires.

@lateulade — So....what’s the verdict?? All well?
