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

[CodeSection]

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.

Welcome! Good luck with your decision.

Haven’t had a blowout yet (knock on wood), but what you said makes a lot of sense. I got a Beast because I have a serious need for speed. Nice to know there’s another benefit!

17000 miles in my dual motor with no blowout. In fact I've never had a tire blow on any vehicle. I wouldn't worry about it.

You would need to be always in beast mode to take advantage of what you’re saying, I mostly drive in chill as it’s easier to keep steady speed. When in beast mode I find my self creeping 15-20 over randomly.

Like you, with decades of driving experience, I have never had a tire blowout. Now, with increased highway driving between AZ and CO, I am concerned about the possibility.

Thus, if there is an edge, like having a tri-motor, to help control the vehicle when there is a tire blowout, I am inclined to buy it just for that safety edge. I know that may not make sense to many, but I would hate to have experienced a blowout that caused a rollover or crash that resulted in an injury or death, and then later live with the fact that I could have spent a little more money to protect better against such an incident.

Thanks for sharing!

Ah, I never knew that. I will mostly be driving roughly 82 mph on cruise control and will be traveling from roughly 1100 feet in elevation to over 7200 feet in elevation, and then settling in at 5300 feet in elevation when driving from AZ to CO.

I would imagine efficiency will go down in beast mode as compared to chill mode. Have you measured the efficiency differences when driving in both modes?

I have not done the math. Others here have said chill is more efficient and if you grandpa your starts you will achieve most efficiency. I have 55k on my CB, done many of launch but travel mostly 45 mph roads in my area. Not any hills or elevations really, my average is 390 Wh/mi on those 55k miles, I can get single trips down to 300 but as soon as I get 75 mph it’s closer to 430 wh/mi ish

Sureeeee you are inclined to buy the Beast just for the "Safety Edge", I told my wife the same thing and I have a Beast. Don't worry, your secret is safe with us. Go for it, you won't regret it. The only blow out I experienced with the Beast was when my wife found out how much it costs. Tires are good tho!! Welcome to the forum

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!

Thanks for the data. That's not bad and is much better than GM's Hummer SUV.

Haha, thanks for the welcome, and I love your sense of humor! While I'm sure there is some truth to what you wrote, I'm really looking at the "safety edge" reasoning. But I guess having that extra power is something I'll just have to live with!

I'm one of those who probably focus too much on safety. For instance, when our two children turned 16, one got a brand new Toyota Sequoia and the other a Ford F-150 Supercrew. It wasn't the issue about them having a new vehicle to show off, but rather I wanted something that would give them better protection because of the newest safety features available and because of the size of the vehicle.

Btw, another "spot on" observation you made.....my wife doesn't know the pricing.....yet.

Honey we definitely need a Beast… it’s much safer

Thanks for the info! I agree with you regarding value. Originally, I was thinking only of the dual motor because of efficiency, and because of reading online that there were problems with the tri-motor. Namely, there were strange vibrations or rattling-type noises when the third motor engaged. I believe they were on earlier productions.

While I do not need the power and speed, if there is a safety edge and if the prior tri-motor issues have been resolved, then I'm interested in the tri-motor.

I guess the missing piece I'm trying to find out is how each model behaves at highway speeds when there is a tire blowout. As you point out, there may not be any significant difference between the two when there is a tire blowout, in that the computer instantly responds and sends power to the wheels that need it to keep the vehicle going straight.

I'll use your line. Hopefully, the name "Beast" gives her visualizations of safety!!
