Rollover in 2003 SR5.. what caused it?

First off, I am alright and nothing bad happened, no collisions by act of miracle.
I was paying full attention to the road at the time of the incident, no fault or citations from the police.

After recovery from all that thinking, I've been wondering what happened or what caused it to do this. So maybe you guys can help me figure it out. Is it just as simple as rainwater and/or hydroplaning? Trying to be constructive here rather than just look for answers like "you suck at driving" etc.


Car is a 2003 SR5, tires were still good before I drove and had more than enough thread, penny test showed tread was still adequate.

A few weeks ago, I was going eastbound on the Maryland I-68 stretch during a rainy day. I had been driving for about little less or more than a hour switching between both the slow and fast lane, averaging 55-75 (top) mph on and off depending on how bad the road conditions were as it progressed through time.

There was a few times during the drive in the rain where there was a tiny quick jerk that I felt on the steering wheel, but did not think much of it. Should that have been something?

Come to a few seconds prior to me losing control of the 4r.

I remember feeling a tug from the back passenger side, like the vehicle was going counter-clockwise all of the sudden for maybe 1 or 2 feet's worth. I can't recall how much, just that I braked fast as instinct to counteract it which probably may have been a bad move, but I'm still listening to what you guys say.

After braking, that was when I lost control. 4r went straight into the center grass ditch and was going towards opposing highway traffic. I remember launching out of ditch like a missile, seeing the opposing cars come towards me for a split second or two. (Was totally in shock like watching a movie at this point), then I remember landing on my driver's side as I slid across the opposite highway. I barely made it into the pullover corner, maybe just the vehicle nose in.

I had to get out via the sunroof, not even a scratch on me or collision by opposing cars by some kind of miracle. Later when the troopers and emergency came, they mentioned they noticed my back passenger's wheel was getting a flat (this was probably 10-15 minutes after the incident). Also for record, it took coordination of 8 people to push the car back on the side.


I went back to check on my car at the yard because I had a feeling it was the last time I'd see it. I noticed I have big scratches on my passenger side, yet I don't recall rollover on that side at all. The most I recall on the incident was sliding on the driver's side.


So this is my question, do you guys have any in the slightest what caused this?

Pics of rest. The tires are Bridgestone Steeltex Radials.

Flat tire.. Bridgestone Steelexs. pic is huge so I didn't encode it directly into the post. From visual inspection with what I had at that time, I couldn't find anything on the tire that caused the flat.

Watch this video, and it will quickly make everyone that watches it understand that meeting legal requirements for depth and actually having safe depth are two different things.

Think about these differences in wet stopping distance:
New tire stopped in 195ft
Tire with 4/32 stopped in 290ft.
Tire with still legal 2/32 stopped in 378ft, and was still going 44mph at the point the 4/32nd tire stopped.

So there you have it. There is no arguing the data.

I'm glad you're safe, but let this be a lesson to everyone that tires can be cheap insurance against a loss of control.
BTW, the tire could have had the seal of the bead broken on impact and caused the loss of air pressure.

Yeah, the Penny test (~2/32") isn't adequate. The Quarter test (~4/32") should be the minimum tread depth you should drive on if you are dealing with rain. I have a tire gauge that gives an accurate 32ndth reading and I generally replace my tires at between 4 and 5 32ndths.

OP IMHO you probably hydroplaned and frankly there isn't much you can do then. Just glad to hear you made it out fine, a car can be replaced, a life can't.

I'd say going too fast for the tires and/or conditions and hydroplaned. The little jerks in the wheel, and the rear coming around in oversteer as described are good descriptions of tires hydroplaning.

Glad you're okay.
 
Glad you're okay!! I actually took a class called MasterDrive which is a class that they teach to new drivers and put them in situations, including hydroplaning, and make you correctly maneuver out of them.

In this class they have a massive tar "field" (if you will) and they water it down with a sprinkler and have you drive into it at 25 mph put the car in neutral and then give your steering wheel a tug and pull the e-brake and then release it. This immediately puts you in a hydroplane and you have to drive out of it. The first couple of times my instincts were to hit the brake and i immediately went into a fast spin which was unrecoverable. The thing they kept saying was, "DO NOT HIT THE BRAKES!!!" it is the worst thing you can do if you're sliding. So when you started to spin and you hit the brakes it caused even more water to collect under your tire making it easier to spin which is why you started to spin. When ever I'm driving in heavy rain and I feel the car jerk like you were describing, i do not even think about the brake. The brake is your best friend but will turn around and be your worst enemy.

Thats my thoughts on what happened, I may or may not be right. Just my 2 cents.

Really glad you're alright!
 
Roll over

You definitely hydroplaned. As the other guys said, in certain conditions minimal remaining tread can cause a total loss of control. I have had issues in the past (with other vehicles) where lousy tires with sufficient tread almost caused me to crash. The tires are the only thing meeting the road. Lack of tread, excessive speed and bad timing can all lead up to a disaster.

Count your blessings and only run good tires from now on.
 
Also, forgot to mention, when hydroplaning, you dont use anything but the steering wheel to steer out of it. Brakes will just collect more water as i noted above and gas will just make your wheels spin even faster. The thing they told me to do was to sit like you're sitting in a chair, with your feet right at the base of the seat and just use the steering wheel to counter the movement of the car.
 
Darn, figures.. I am not a fast nor lead-footed driver and usually stay within speeds limits and speed the lanes are going, but perhaps I should have been less confident in the rain.. I still even remember the F150 in front of me, thinking that guy was going a too fast for the conditions then it all blew up and happened in front of my face.


Now I know what to do in the future in the event of hydroplaning again. The experience is definitely a 'WTF' feeling, I ought to look into the Masterdrive courses.

I am originally from the west, and did not think of the conditions being as drastically different as there, but I ought to know better.. And yeah.. someone in here uttered the same quote word for word that the trooper said.. "Cars can be replaced, people can't."

Would a 4wd 4r have prevented something like this (loss of control, traction, snow conditions etc), if the key issue was not tire tread depth?

Well, I can say that my 4wd is amazing! It picks up that slip and you can feel it actually fix itself and if its bad enough slip than it starts beeping and does the work for you pretty much. Except for the steering OBVIOUSLY!

I will never buy a SUV without 4wd. I LOVE IT! :bigok:
 
Roll over

Hearing that you had a 2WD explains things better. Rear wheel drive trucks with higher centers of gravity are especially prone to roll over. The 4WD V8 is full time four wheel drive and has traction contol. That does not give you an unquestionable license against spinning or flipping, but it sure makes it much less likely.

Were you on 4WD?
 
OP glad you're ok.

The rims the OP has are the standard 16" rims. The 17" wheels are optional on the SR5, though most 4th gen SR5's came with the 17" wheels and few had the 16".
 
LT rated Steeltex couldn't have helped with the hydroplaning, especially if the were set under 40psi or so.

Those tires are not known for being good in the rain when inflated to pressures commensurate with their intended application (F350 size truck). The pattern and the compound is not a favorite. Unless you had them pumped up pretty hard the less-than-favorable-traits combined with the hydroplaning speed of a tire at 32-35psi is recipe for near disaster.

Very glad you're ok.

Will you look for another 4Runner?
