First Time EV Owner: Live experience report

[Scout_Lookout]

Are any tire manufacturers excluding/reducing EVs from their tire wear warranty? I know my car gets the warranty cut in half for having staggered sizes front-to-rear.

On an EV, I'd think different tire diameters front and rear should be easily accounted for in software. It's not like the computer doesn't know what rpm each axle is turning on a straight road and it's not like it makes any practical difference if one axle is running slightly different rpm than the other. On the other hand, my Toyota with full-time 4wd and a lockable center differential should have minimal diameter differences.

Actually, unless you buy an extended warranty that specifically includes tires, the manufacturers wont warranty them at all. There are some, (like Logan experienced above with his Ioniq 9 and their Kumho's) that will give what is called a goodwill credit for special circumstances.

So here’s another question. Let’s say we get 33s at purchase and decide to switch to 35s is that an easy switch in the screen to pick a different tire size?

Yes, enhanced wheel and tire tire change functionality is "built in" to the Rivian SERVICE menu. You can report which wheels and tires you are running, which is then used by the truck to determine accurate range estimates and track mileage automatically at rotation as well. Really nice interface and very easy to use. If I remember correctly, this was added as one of the OTA's by Rivian after launch.

Sorry, I meant for replacement tires, not OE tires. I usually get 10k-12k miles out of a set of 30k mile tires and get prorated discounts on new sets.

For EV's that sounds about right. Price we pay to save the world and look good doing it.

Do you have a favorite tire already? They may make it in XL load rating - that's the key thing to look for.

For long life I would look at the Goodyear Assurance or Bridgestone Alenza.

I am loving the Pirelli Scorpion Zero All Season on my MXP but they are spendy ($420/tire for your car) and are more performance oriented, but still an all season, not summer tire. I'm at nearly 20k miles on them and still have plenty of tread left. In contrast to the OEM Michelin Pilot Latitudes that didn't even make 20k, but they are a summer performance tire.

I've had favorite offroading tires in the past, but I haven't ever really had a favorite road tire. Thanks for the recommendation, and I'll keep them in mind for the next go around.

And I'll be curious to see how long these next tires last. They were priced fairly similar to the ones on your list. And at least these ones will have a tread wear warranty with the pro-rated amount being reimbursed if we get less than the tread life. So, if we get 25k miles out of these ones, which have a 50k warranty, we'd get 50% of the purchase price credited towards the replacement tires. So at least this should help reduce the financial burden each time this happens.

Again, most of the time I heard about people with super crazy short tire life on their EV, most of the time it was people driving "with spirit", in an ev with lots of power. My wife and I comfortably drive our Tucson PHEV with a ~9 second 0-60 time (if you're on EV power only, before the gas motor kicks in, which drops it to 6.5 seconds), and almost never kick in the gas engine. We drive our Ioniq 9 similarly. We are not racing around.

It's all good. I a lot of people have no idea there's a difference and honestly I dont think there should be. Making tires is not the cleanest business and IMO OE's should have to just pick from whats available to prevent these kind of experiences.

However, with EV's because of the characteristics I think tires are just going to be one of the few pain points (I replaced my 20 inch Pirelli All Seasons and put new AT's on my Rivian at 22K). Unless you get a much higher rated none EV tire I wouldn't expect to get anywhere near the mileage the tire says it can go, but I agree 12k is ridiculous on the OEM tires. With that being said I can remember early Tesla days when the new Model Y performance on the 21 inch Uberturbine wheels were regularly getting between 12k-15k and customers were not happy at all about it lol!



Actually, there are no good options for this on Rivian currently, because you can only choose from factory made options (past or present) when changing out wheels or tires. Honestly, this is an interesting idea for Scout and one I dont think has been mentioned yet. But seeing as many of us will be modifying our Scout's it would be really nice and convenient to have the option in the infotainment for larger tire swaps that will then recalibrate the speedo automatically.

Lastly, when replacing the tires on any one axle there should not be a difference of more than 2/32, especially on AWD vehicles.

Yes, I knew there was a difference between the EV tires and non-EV tires. I just am not sure how "much" of an efficiency/sound hit there is with non-EV tires. Do you by chance have any data on that? The noise thing I'm sort of ambivalent about, but the efficiency one I am, mostly for those road trip situations.

But if the other non-EV tires are likely going to last longer, it might actually negate the efficiency loss enough that it actually ends up being "cheaper" to run them. With the only actual downside being lower range on road trips (which are infrequent).

And yes, the situation was that the new tires were going to be 4 or 5/32" different than the tires on the same axle. The rears were at 5/32", and the stock kumhos were 9/32", hence the predicament. Additionally the fronts were at 4/32". So I couldn't do just one tire on the rear axle, and since the fronts were pretty close to where we'd usually replace them, we just did those at the same time.

Now, with a mechanical AWD system with clutches/etc, even if they weren't on the same axle, it could cause issues (at least that is my understanding). But with two motor AWD systems like I have, I'm inclined to think that the axles should be thought of as individual units, I just don't have any data on those.

No idea where to put this, so how about here. And I have no idea if this is a dumb idea or not but I’m throwing it out there anyway.

I was thinking about @J Alynn and his wife and how the key fob died. Now I just had to plug in my Apple TV remote because it said it was less than 20% charge. Is there a reason you cant just plug in your car key fob with a USB charger and charge it when it gets low? Is that a thing with any manufacturer?
