Tire Blowout - Safety Benefit of Tri-Motor vs Dual Motor

[CodeSection]

FSD is disabled when towing or when the tailgate is down.

Thanks for pointing that out! Now that I think about it, it makes sense.

I’ll add this, as CT isn’t my first Tesla vehicle, all these cars are bonkers safe. I doubt we humans would notice a difference in post-blowout handling of the dual v tri. Don’t over think it. Dual motor is a better value, there’s no logical argument against it. Beast is stupidly, unnecessarily fast, can’t argue with that either. Do what makes you happy!

I’m the happiest Mutha Fer on the planet with two 2024 FS Cyberbeasts!

You bring up a great point, however I drive 99% of the time in FSD, I have to believe the tire blowout factor has been calculated in when designing FSD software, I don’t believe that the 2 rear motors would have that much of an impact on a front tire blowout. I have 2 Cyberbeasts, and have driven the AWD up and down the east coast from New England to Georgia. Just make sure you have a spare tire, bottle jack, tire repair kit, tire inflator. Lug tench, and plenty of rubber gloves, and towels.

Get a beast! most people that own and all wheel drive, regret not getting a beast, most people that own a cyberbeast will never regret not owning an all wheel drive.

Like the pictures with those colors and the "buyer's remorse" statement! Now that you mentioned a spare tire, I never really considered that, and that will take up precious cargo space I need. I was thinking of using a "fix a flat" can or something similar for potential flats.

I'm curious, how many CT owners carry a spare tire on long trips? I guess I could have a spare tire, but then I would need to have the tonneau cover open and possibly install side panels.

You gave more to think about. Thank you!

Oh yeah, your buying the Beast for "Safety" wink, !

If you can afford it, get it because it's crazy fast, fun, comes with FSD, Supercharging, etc ... Not because in the extremely rare event you get a blowout, you think your going to die if your driving a dual motor CT instead of the Beast.

You definitely make sense. I'm surprised I haven't read or heard of a tire blowout in a CT since there are at least 50,000 (?) on the road now.

I would buy the CyberBeast if it made a measurable difference in safety. I do not need the extra speed or power. As for FSD, I believe it is cheaper to buy it à la carte.

Free Supercharging may be nice, however, the breakeven point in paying extra for that vs just paying the .62 kWh via EVGO or EA for our trips, along with charging at our different homes and only paying .12-.14 kWh, is waaayyy too long.

In my case, it would be cheaper to buy the dual motor and pay extra for FSD and charging. I can invest the money saved and be further ahead....

Thanks for writing!

In the age of radial tires and TPMS, blowouts are as rare as hen's teeth. Most people will never experience one, as a driver or passenger.

Thanks for writing! I have never experienced a blowout and hope I never will. Maintaining tire maintenance with proper air pressure and rotations goes a long way toward safety.

You got me thinking, I wonder what is the #1 main cause of a tire blowout....tire pressure? Object in the road?

A few things. Have not had a blow out in the CT, just a slow leak from a nail.

Also, not sure if all 3 motors are “on” in FSD and while likely cruising on the highway.

Im not sure the help against “pulling” is a per motor thing as much as it is a traction control thing dealing with torque vectoring. So it may come down more to what cars have better software for dealing with it.

As for blow outs I’ve had one at over 120mph on a long sweeper (on Easter with my aunt in the car!) that was off camber putting even more weight on the blown out wheel, in a sports car. Weird pull and balance dealing with the pull and somewhat giving into it, but not fighting it too much. Almost how you might “use the force” in making very small adjustments when you hit a long long long patch of ice.

By the time I stopped on the side of the road and the tire was almost completely off the rim doing some damage inside the wheel well. By some miracle the rim didn’t hit bare pavement as the wheel was still on by maybe the last inch. Which is to say, I can’t think of a blow out that could be much worse, albeit it was in a vehicle of less than half the weight of the cybertruck.

While I don’t recommend having this trip, as long as you keep calm, don’t over work the wheel, you should be ok.

That car had some advanced traction control but it basically didn’t do squat about the blow out. It was a 2012 car with pretty advanced traction control for the time including brake steer. I’m not sure anyone programs their TC to handle blow outs, but I would love to see comprehensive testing on the subject.

Wish I had more detail to give than the above, but weirdly living through what was pretty close to a worst case scenario makes me feel a bit better in that it wasn’t as bad as I feared and hopefully if it happens again it’s likely to happen under less stressed conditions.

Monitor your tire pressures like a hawk! In my above blow out I left the house and one tire was lower than others but I thought it was because it was cold. Turns out there was a nail and the tire had a slow leak. What caused it to literally explode is tire speed at the top of the tire is 2x your actual speed. So at over 120, the top of the tire was past 240mph, and the sheer forces basically Causes the nail to fly out and it literally exploded the tire as it ripped out!

So I’m not sure if that’s a common cause, but certainly can be a cause, particularly if the nail/screw is more on the sidewall of the tire.

I had a blowout at 75 mph while towing on my ford excursion, the tire exploded and caused a lot of damage in the left rear quarter, of course the rear air conditioner and heater hoses were destroyed! I was on I95 North Carolina, I just moved Right, to the break down lane assessed the damage and called AAA. Final tab approximately $6500 in damage. Remarkably, the truck handled extremely well as the tire started shredding, and my truck did not even hit the rim on the asphalt. And it was the spare tire that blew!

Is that spray foam in there?

The extreme pull to one side of the road after a blow out is not caused by the engine/motor, it is caused by the tire not want to rotate like the other three tires.

We are planning on buying another EV SUV or EV truck that will replace our Sequoia. We looked at the Model X, but it is too small and does not have the cargo space needed. We want a Tesla, especially with all its features like FSD. We love driving the Cybertruck, and it would nicely fit our cargo needs. A CyberSUV would be ideal!

While researching motors (dual vs tri), I recently came across a YouTube video showing a Rivian R1T having a front right tire blowout on the highway. The Rvian had quad motors, and the blowout did not cause it to extremely pull off the highway as what happens frequently on ICE vehicles.

The purpose of the video was to educate about the safety benefits of multiple motors on EVs. According to the video and my research after Googling, when it comes to tire blowout safety, the rankings from safest to poorest vehicles are ones with quad motors, tri-motors, dual motors, ICE 4-wheel drive.

We are now considering buying a CyberBeast with tri-motors instead of the Cybertruck dual motor model.

Has anyone experienced a tire blowout while driving on the highway with either model?

Sorry about the long first post. I just wanted to give some background.

I am not sure if you have ever experienced a blowout or not. They can be very dangerous, but typically they are not. Typically a dangerous blowout would be at high speeds, and would effect a front, primary steer tire. I have had a blowout in a rear drive turbo BMW while traveling on an interstate in FL. I was driving with the flow of traffic, interpret that how you will. The car had low profile performance tires. It was rear drive, and I was easily able to maintain control. The tire did significant damage to the car (fender, fender liner, and fuel fill line ), as I slowed from highway speed to a safe stop on the shoulder. Interestingly, I was on my way to buy new tires.
All of that being said, the Beast has dual rear motors, but a single front motor. So I do not think the dual motors would impact a blowout the way you expect. I think Beast and AWD would handle a front blowout in a similar fashion. That said, you are driving one of the safest vehicles of its kind, on the road. When traveling at higher speeds, make sure the vehicle is set to a lower ride height, this will add to your safety.
Side note, if this is because you are hoping to justify to your spouse, buying a beast over all wheel drive, then everything I said above is false narrative, meant to deceive, and mislead. Including my anecdotal response, about a completely different type of vehicle.
