Huge range loss after new tires
My M3 is getting 30% loss with new sets of tires from Costco.
PILOT SPORT AS4 235/45ZR18 98Y XL BSW
Any recommendations, should I change them to another type. I live in SoCal and driving as normal as possible just commute to work back and forth
Appreciate all your help
Those Pilot Sport AS4 are not high performance tires. They are a solid all season tire that shouldn't have that much of an impact. Did you reset the tire configuration as detailed in the manual?
"If you replace your tires or install different ones, reset the tire configuration (see Tire Configuration). This resets the learned tire settings and improves the driving experience on your new tires. It may take up to 24 hours after a tire replacement or repair before the tire lubricant is completely dry and tires achieve maximum adherence to the rims. Avoid hard accelerations during this period to avoid tire slip on the rim."
"To see the miles driven since your last tire rotation or replacement, touch Controls > Service and look under Last Tire Service. After the tires on Model 3 are rotated, replaced, or swapped, update your vehicle's tire configuration by touching Reset, or by touching Wheel & Tire > Tires from the same screen. This allows your vehicle to reset the learned tire settings and improve your driving experience. This also clears and resets the tread wear alert for the vehicle until you travel (10,000 km) and low tread depth is detected again."

I came here to say this. 👍🏻
I apparently came here to learn this
Saved.
Pilot Sport AS is a “high performance” all season. No, not a true summer tire, but definitely higher performance compared to a GT tire.

They do.
Even the AS4s are designed significantly for performance. It will be notably less efficient than any EV tire designed for low rolling resistance. New tires are less efficient than worn tires generally (tread blocks flex more).
For commuting: Hankook iON AS.
I would check out the new Pirelli AS Plus 3 if you want a UHP AS tire, they have an EV version
How can updating it via software increase your efficiency..? Much confusion
It won't increase efficiency but the car will adjust and make more accurate predictions based on the tires that are on the vehicle.
If you replace them with the same tires, are you required to reset the configuration?
Yep perfect mine did a similar thing with different tires
I've said it before and I'll say it again - switch to %.
Only way to go lol. I had horrible range anxiety when I never needed to anyways. I never fell short on my daily commutes. Switched to percent and just drive normally
New tires typically have higher consumption in the first 1000 miles
Why is that? Excess rubber?
Wearing in? I'd assume it's like new shoes where you're not quite worn in to be comfortable yet.
Source?
Question. Are you comparing these tires at the same point in there life span or are comparing new tires to old? Im curious how much of a diffrence is just new tires.

Yup. Same here. https://www.reddit.com/r/TeslaLounge/s/BnYJulIQt8
Well yeah, you bought high performance tires.... What did you expect? If you want max range get a grand touring tire
What should I get replaced, I was just looking for 45K mileage warranty
Mxm4, kinergy gt, turanza EV, ion evo as
Michelin MXM4 OEM tires lasted only 20k miles which came with the car, so I did not get them
I’m just replacing mine now, > 92,000 km.
It’s not the tires.
Hankook iON or Pirelli PZero Elect.
They have great efficienc and are quiety, but are total garbage for handling a car with over 300hp. I like my cross climates and don't care about range much, but I pay 12 cents kwh in Texas. I do miss going 200 miles doing 85 in one charge. I think the mxm4's could still make that happen.
What region are you in? What are your driving habits? Do you get up to speed pretty quickly or do you drive like a grandma and take a minute+ to get up to speed? I notice a lot of people say they don't drive fast but then they speed from every light like FSD does, which, while isn't the same as flooring it, does introduce a lot of wear.
What model do you have? And what's your total Wh/mi? So we can get a feel for more dialed in answers. P is going to naturally use more juice for the two motors vs RWD, etc.
AS4 will probably wear out faster than MXM4, so at least you can learn from your mistake within 18k miles 🙃
Mine lasts 16k switched to hankook ION AS
I’d say nay on the kinergy gt’s. My car came with those factory and they were terribly rough and noisy, very good efficiency though
Usually to get great mileage the tires have to be stiff.
You might want to slow down.... you literally used up most of your mileage because of speed. It's right there on the screen 🤦🏽 Granted you're using sticker performance tires now... but it's really that simple.
Exactly. Bro complains about range loss yet exposed himself that he’s driving too fast lmao.
To have that much loss you have to be cruising at 90/95mph. Cause I was just traveling in an area with 80mph speed limits and saw little to no range loss compared to the estimate going 80-82mph.
Lucky you. Last summer, driving 85 in 105 degree ambient, I lost a LOT of actual range, maybe 40% of calculated.
Holy moly, I've never had my "consumption vs rated" bar be so far to the right. Looks like you were just hammering the car and/or maintaining 80+ mph. Can you provide your driving habit and how fast you were going on average?
I replaced my stock tires with extreme contact ones for better grip as I have sketchy roads to drive in the rain a few times a year. I feel locked onto the road, but that friction comes at a cost… I get free charging at work though so I don’t have to pay for that cost.
Brand new tires will hurt EV range regardless of what tire you get. Tirerack did a bunch of testing and that was one of their findings. They talk about it in this video.

Have these tires now. They will be super sticky initially but you will barely notice range loss, if any
Those tires could get about 10% less, but not 30%. Something else was going on.
I saw 20% loss when I went to ps as4 myself on my m3 long range. I got most range back over time when they smoothed out but went to hanook ion evo as and saw a great return of range.
The newer the tyres, the higher the rolling resistance.
Also check tire pressure - every tire I’ve run has needed 42-45psi for the right contact patch, and I’ve had 2 shows send me out at 36-38psi. It easily makes a measurable difference.
I would suggest you switch to Michelin Primacy Tour All Season Tires. They are OE on Lexus and I have had very good mileage on my M3LR, even better than Michelin Primacy MXM4, and costco carries them. So it would be easy exchange under thr Michelin 60 day satisfaction guarantee.
I will wait for 1k mile break-in to see it improves and I am also will be within 60 day warranty period
I'm going through exactly what you are, I just put on Michelin primacy all season and this is what's happening to me, I'm at 10k km and my graph is just like yours, I drive 225 km a day car has 165k km on it had it since brand new. Let me know please if you find out anything. I've reset tire configuration and everything
Here is what I had used from Costco
MICHELIN PRIMACY TOUR AS 235/45R18 94V BSW Item 1508584
This is what I have on my car now.
And you have loss in mileage? What tires did you switch from?
Same exact ones that came with the car just new, I have an alert under the service menu DIR_a018_hw12vSupplyUV, not sure if this is the reason, cannot find enough info on the alert
Drive is 115km usually use about 20 percent it's consuming 25 percent, steady pace at 105km no climate on in the car. I've done this drive for the passed 3 years, I'm currently consuming as much battery as I would if it was cold outside. It's everyday not just a few days, I have a 21 lr.
Tesla does not ship with Michelin Primacy Tour AS. It ships with Michelin Primacy MXM4 AS
Ahh thanks for this, I sold my tires last year so this year I thought I grabbed the same ones. I was like what in the world has happened, I knew it wasn't battery cause it was right when I changed them, next time I will be getting more efficient tires
Either will work. They are both within load specifications however Costco will push for 98 as that is what most Model 3 come with. Mine came with 94v tires, btw from factory

By the way, what were the original tires that you are comparing against?
Go into service mode and see if you have any errors,
I have this one
DIR_a018_hw12vSupplyUV
I noticed a clear increase in my power consumption for about 500 miles on new tires, then once they were 'broken in' it settled back to normal.
This much decrease is odd. I have the same tires and noticed almost zero difference maybe an extra 1% in every 20% i drive . Are you sure you’ve been checking this screen often before as well? One thing that absolutely kills range in these cars is driving over 70.
Kinda looks like you were flying (70 mph+) after the first 15 miles. Nothing wrong with that, but the efficiency loss is probably not on the tires. :-)
Yup
I get about 8% less range on those versus the stock MX4Ms. So about 20 miles real world, it’ll be a bit higher before they break in a little.
I have these exact same tires from Costco but only went with 245 which is a little wider. Old tires were worn out so efficiency was a little lower than new tires. These new tires took at most 10% range maybe has to due more with width. After couple thousand of miles range and efficiency looks to be the same as with stock tires, maybe tiny bit less but not that drastic.
PS4s have much better grip compared to the original mxm4s - efficiency is lower but not that high
I have always run AS4s. I have never seen any range hits at all compared to OEMs.
So never run oems because you always run as4?
My M3P came OEM with Pilot sport 4s. First change out I went to AS4s. Tracked and compared both over 35k+ miles. No discernible difference. My MYP came with AS4s. I am at 297wh/m and the car is rated at 295. So, I would say the mileage hit is not the tire brand. The AS4s perform very well. Must be something else. Tire inflation, wind, speed, etc.
More tread is going to hurt rolling resistance. Tread pattern may hurt rolling resistance.
I ran the same tire in 265/40/18 on 18x9.5 wheels and averaged 265wh/mi. It's normal to see a spike on new tires but I never experienced that large of a range loss unless temps were near freezing.
it will be about 5000km before the consumption gets to normal. My cc2 took about 10% worse at the beginning but now its like 3-5% worse
This is normal, reset your tire service settings
New tires are always less efficient at first. If you've never had this model tire before, maybe they are less efficient than your last which is making such a huge impact.

Interesting video I just watched on EV tires and how they affect efficiency. Doesn't sound like it should be as much as you are dealing with though.
From the data read out of your speed, I’m guessing you’re cruising well above the speed limit. Like at 85-95mph which is no wonder.
Considering the flow of traffic in SoCal is 75-85mph where you’re at.
No, this is not true
It literally tells you 15 of the 18 miles used more than estimate is due to going over 70 mph…
Double check the PSI.
Mine was set to 41, is it correct ?
The stock mxm4 are super efficient but are pretty shiet around corners. My tires were squealing through u turns so I was happy to make the trade off when I switched to pilot sport 4’s.
….this chart just shows your driving as the number 1 cause and is not in any way a scientific evaluation.
I would expect less than 10% loss unless the tires had 5psi, which you said they didn’t.
This screen isn't the best way to figure out efficiency for the tires. Usually, if you're tracking a trip over a longer time or distance, you would have a better idea vs data from one drive.
For example, every time I change to my winter tire set, I have a trip that I reset which tracks overall usage for the winter tires. I can compare that over time to the other tire set to get an idea of efficiency differences. Wh/km or wh/m for the tire set over a period of a couple of weeks which includes mixed driving conditions compared to similar conditions with your previous tire set is a better way to compare the two.
FWIW, I’ve been running Continental Pure Contact LS. Tread life has been MUCH better than stock. Efficiency is down a little, but not by much. Price is reasonable for a name brand tire. Tradeoff is grip is not quite as good as stock, but kind of expected that with the 700 UTQG rating. 🤷🏻♂️
Yokohama has done well by me on my previous Model 3 and will go on my new one when it is time.
You’re going from bald old tires to new tires. It will be 30% but will gradually decrease overtime
New tires will always have more rolling resistance than old ones. As well, you bought higher performance tires that will inherently have more rolling resistance than the ones that came with your care (unless it was a Performance version).
It's more likely AC/ hot weather. New tires do consume a bit more until it breaks in like in a few months. But it wouldn't be 30%. Something else is going on.
You were driving 70+. Air resistance is over 80% of efficiency losses and a difference in tire would’ve accounted for maybe 5% of that
Second set on this tire now. Usually there is about a 200-500 break in period with the new tires. You need to reset the tires in the system and run for some miles. I noticed about 5-7% increase in wh/mile on both sets. Still pretty solid comparing with the OEM.
If the tires aren't low rolling resistance, your range may suffer, especially if you're replacing ones that were (which they likely were).
Also, new tires are stickier than old, wore out tires, so you'd get a range hit even by replacing the tires with the same ones you had.
I feel like tire buying is the wild west, with little information from the manufacturer, and few ways to compare tires well enough to end up with what you want.
Well yeah you’re driving 90MPH lmao
My vehicle also consumed 10% more than anticipated on a recent drive that should have only consumed 35%.
Cant help but feel something is up
OP I have Pirelli P Zero As Plus Elect tires. They are all season tires specifically for EVs. They have low rolling resistance and my efficiency stayed the same as with factory tires. Which ever tires you get make sure they are EV approved, otherwise your efficiency will suffer. I had to explain this to employees at my local tire shop, they had no idea.
Like others said, the fresh rubber on brand new tires means you have worse efficiency starting out but after about a month of driving give or take it hits the average.
Is there a good place for guidance on “EV Specific” tires to read, to get the best balance of efficiency VS capability?
So the Trip module told you that you were driving at a higher speed which is why you consumed more than it estimated. And you came on Reddit and posted " why did my new tires lower my range?" , attaching a screenshot with the exact image saying it was your speed..... are you serious?
It looks like it also has additional warnings but they're cut off on the screenshot. Something about climate
until op responds we won't know but my guess is before the new tires, he drove the same way and didn't get as poor of mileage efficiency as he is getting now with his new tires.
