Changing tires on Cybertruck. Anyone know??

[daddyd]

I’ve asked multiple reps at the dealership questions about the Cybertruck and they are so clueless it’s actually kind of hilarious. Anyone else see that? They can’t answer any questions about anything aftermarket whatsoever. But I’m curious if any tire people out there know if it’s possible to use any tire on the cybertruck? I have Toyo Open Country M/T’s on my Jeep right now, and I think it’s my favorite aggressive tire. I want to put some on my new Cybertruck whenever it comes (not worried about range, I drive minimal distance for work) Is this tire possible in a 35 on the cybertruck? I saw a YouTube video where they did Nitto Grapplers and he mentioned tire choices are limited. No clue why. What about a mini lift or spacers? I want to treat my CT like a truck, but can’t find any info on what you can do to this thing. Any guidance would be appreciated!

If you don't know why the tire choices for a truck like this are limited, you probably shouldn't put anything on other than the OEM tire.

I understand it’s an EV. Very different. But I’ve never owned one before. And I’ll admit I don’t know much about tires etc. That’s why I’m here asking if you can put 35 Toyo MT’s on the CT? This is the only source of Cybertruck info you can find anywhere, so wanted to see if it’s possible. I think it would look amazing if you could

There are some restrictions, particularly in the front because of the clearance to the upper ball joint stud .

I personally have no experience (yet), but check this video and general for more info.

The main issue is the weight. I can go get nice and cushy C load range 35s for my wrangler, but I can't get a nice and soft tire for the truck. So even if you do find the one or two options that come in a crazy load range and are the right size to fit the truck, the road noise and comfort will be pretty terrible.

As for the tire you're asking about, it only comes in a Q speed rating, so the car can go faster than the safe speed limit of the tire (99mph). It does look like it comes in a high enough load rating though. You'd also need extra offset outward to avoid rubbing I believe, since they are wider than the OEM tires.

The included picture is the exact spec that seems to work the closest, but it's still not a 1:1 replacement.

Love the Toyo Open Country. Back in '06-'08, I had 40x15.5x22 on my Super Duty. Never balanced them and they still rode smooth as glass.

If the specs are good enough you can put whatever tire. Just check speed and load rating. As far as fit goes, you're in uncharted territory. If the specs work and you have them I vote try it.

I just put my model Y rims on my model X and I've seen one whole other person do that on the interwebs

A tire for an EV is different in a couple areas from other tires.

Because EVs are sensitive about range, tires are a big player in the range of the vehicle. Look at the 30 mile difference between the AT and AW options listed for the Cybertruck.
A big part of this is the stiffness of the tire. The old style radial tire that spreads out of the road like putty is the antithesis to an EV tire. The Model Y and Model 3 tires are relatively narrow and pumped up to 42psi. They are stiff and decrease rolling resistance.

Many of the Tesla wheels are subject to curb rash because the tire doesn't protect the rim like they do in other vehicles. Look at the wheel/tire from the rear and you will see that the tire is narrower than the wheel. On AFAIK, every other vehicle, the tire is thicker than the wheel. The smaller the footprint, the lower the rolling resistance.

Because of the stiff wheel, many EVs use tires with internal sound dampening.

Because the batteries in an EV increase the weight, the load ratings for EV tires are often higher than an equivalent vehicle.

And of course there's the basic physics of does it fit and not hit parts of the vehicle.

Yes, you can put other tires on the truck, but the market is pretty immature at this point.

But what works on a light Jeep probably won't on a heavy Cybertruck

In my experience, if you love a certain tire on a particular vehicle, that's a very poor reason to choose the same model tire (even if in a different size/load rating) on a very different vehicle with different chassis flex, different suspension geometry and different alignment specs. Tires that work well on a vehicle do so because the specific characteristics of that tire suit that vehicle very well. Your Jeep is a very different animal from the Cybertruck.

If anything, you should avoid tires that are particularly well suited to your Jeep. Every major manufacturer makes some great tires in most every tire category, so it's not too productive to start limiting yourself to brand and model when selecting a tire for a different vehicle.

The issue comes down to the weight index and speed index - how much weight can the tire support at full pressure and at what max speed will it stay together without flying apart. The weight capacity of the truck it also limited by the tires.

With the Cybertruck's weight of roughly 6600 pounds + 2500 pounds of load capacity, that is approximately 9100 pounds. Divide that by four tires and you have a tire load need of 2,275 pounds/tire. That is a tire index of 110 (or better). Now, I do not have the Cybertruck tire specs in front of me, but a blurry photo I looked at appears to show the stock all terrain tires have a load index of 120 = 3086 pounds/tire.

The stock Cybertruck tires look like LT315/60R20 M+S 120/122H
- LT - class, light truck
-315 mm width
-60 aspect ratio
- 20" wheel
- M+S = mud and snow aka all terrain
- 120/122 = tire index (the second is if this is a dual tire config - think dually pickup)
- H = speed rating

You can look up tire load indexes here: https://www.goodyear.com/en_US/learn/tire-basics/tire-load-index.html

Load index is a more modern version of the older load range (a letter rating that used to equate to the number of plies - aka Ply rating - if a tire had more plies, it could support more weight). The Cybertruck tires would be rated about an 'E' tire load range. But Light Truck (LT) tires usually have a load index while some tire sites still list tires with a load range even though the tire may have an index listed after the size..

That last thing is the speed rating - Cybertruck tires are rated 'H' - or up to 130 mph. Here is a good article and chart on speed ratings: https://www.tirerack.com/upgrade-garage/how-do-i-check-a-tire-s-speed-rating

So, when looking for your tires, it comes down to:
A) Do they fit? I saw a post with the TSportline.com video of how a 35" tire on the 20" wheels just will not properly clear the trucks wheel wells and protrusions.
B) Will they support the weight of the truck and what you would put in it? It is always better to have tires that will support the full weight of the vehicle and not just its weight plus people - so I would stick with an index of 110 or better (higher for safety)
C) Will they support the max speed at which you will ever drive the truck? If you never see yourself going 130mph, then you can look at lower speed rated tires - which opens up a wider selection.

Long answer to a simple question - but now you have the info to make a decision that is good for you.

What I would like to do is put A/S tires on mine. The only ones I've seen as a recommended possibility are the Michelin Defender LTX. Anybody has thoughts on these? I am looking for improved range, better handling on the road, and better snow handling.

Thanks.

I was at the Parachute, CO Supercharger 4/21 and saw another Model X with the Model Y 21 inch performance rims. I was leaving so didn't ask him about his motivation. Looks cool.

Thanks for starting this thread, OP.

This is going to become even more important when the non-foundation version comes out. I am expecting the stock wheels and tires to look way cheesier than these 35’s (which will of course be available as an upgrade, which isn’t going to be cheap).

The question then becomes, for people who want different wheels and tires, are you able to pick something out that is better for your use case and better looking than factory for less money?

 

[countryboy]

I plan to get these in 285/65-20 when my OEM get worn out - Goodyear Wrangler UltraTerrain AT | Discount Tire only Q (100MPH) speed rated, but I don't plan on going that fast.

Do you have an urgent need to swap them out now? You may want to wait until Tesla releases their A/S tires later this year.
