Exclamation Death by tire pyrolysis, especially for you welders & torch owners

Watch this amazing video from Bridgestone. It's possible that a tire & wheel can blow from just a little heat on the wheel from welding, torch, etc. with devastating results.

OK, I am the commercial Vehicles Manager for a big corporation and I have these comments. There is nothing on a wheel that ever needs to be welded. If it has a crack it is trash. Plus why would anyone even think of welding a wheel with a tire mounted.

Here is something I learned recently. If you are replacing only two tires on your vehicle, any vehicle, where do you install them. Front or rear and why.

I would never just replace 2 tires on my vehicles, but to answer your question I would guess the front because that's where most of the wear and tear is...?

Was the weld only applied for 2 seconds then 2 mins odd seconds later it exploded as a result?

That is exactly what happened, the welding stick was only on the wheel for several seconds & the wheel/tire assembly exploded 2 minutes later.

I concur with the rim should never be welded or heated and should always be thrown away. What got my attention was one of these was caused by heating a lug nut to remove the wheel. Ask your shop foreman if they have ever used a torch to get a east coast lug nut off and if you don't you are pulling the hub to replace a stud you just broke off with that one inch impact.
Answer: front of the vehicle.

I would also say the front of the vehicle. It would need the traction more on the road for turning.

Rear of the vehicle. The reason is because if the rear tires are worn, it is easier for the vehicle to lose traction in a turn or emergency breaking situation.

That makes sense. Just like if the rear brakes lock up, you're out of control with an instant slide.

I don't know why, but I know that last year I had to replace a tire due to a nail too close to the side wall and was told the new one should go in the rear.

Good Answer. Tire Industry Association recomend this to prevent the rear from passing you in an oversteer / understeer situation.

Personally though I will still run the higher tread tires on the front of My Jeep.

might be Different if I had a Honda.

For years I thought it was the front for steering purposes. A couple of years ago I was invited to the Michelin Tire Center in SC for a truck/bus seminar and on the last day they asked each of us this question. But thet did not give us the answer they showed all of us. What they have is a 1 mile wet track and two identical cars, one with 30% worn tires on the front and one with them on the rear.

We all took the vehicle with new tires on the front and went out on the track and tried to go as fast as we could. Everyone of us lost control of the vehicles very quickly and did 360's. Then we took the other car out and it was unbelievable how well we could control the car with the new tires on the rear.

The main purpose of the seminar was to showcase their new single tire that replaces the dual tire setup on the rear of big commercial trucks and how to diagnose tire failures.

Jerry, you would have loved it.

I would be more concerned if the front brakes locked up.

I've done the torch to the lug studs before on an inflated tire. Figured it was for 10-20 seconds only and I did get the rim off. Never even thought about it blowing up for only 10-20 seconds of heat.

Glad I'm still alive. Good video. Already forwarded it to 3 people I know that work on vehicles.

I think a torch heating a lug nut is much different than welding a cracked wheel. Welding the crack applies massive heat to fuse the wheel where as heating the lugnut does not.

Thanks for posting this Jerry. I have had to put out many car fires and I have never even considered the possibilities of a tire exploding. I am sending this on to my fellow corner marshals.

And all this has to be put in context. Atthehop's point about putting the best tires in back does make sense, and Jerry was just makiing a point about locked wheels having no traction.

I locked a passenger side front one time and that was also scary. Down hill on a mountain road with a steep drop off. (Not in a Jeep). I dis have some control, but not much.

A good rule of thumb for autos, airplanes and boats. No matter what happens, continue to drive the vehicle.

I am sure glad you folks are here to keep an old man on track. I had a Good Year store refuse to put the new tires on the rear many years ago and now I find out the truth. This appears to be the video at Michelin.
Thanks
Bill

That's the Michelin test track I drove on and learned this information.

It is ok to weld a wheel. I have used these guys in the past to repair a damaged rim on a mustang when I lived in the Dallas area. It is not ok to weld your rim at home but like many comments made as absolutes there are some exceptions.

WOW!
I've welded/repaired many wheels with tires on them, both in the shop and on the trail. I had no idea it's that dangerous. I guess I've been real lucky. Never again!

Yes, it's obviously safe to weld a wheel without a tire on it - most wheels the center is welded to the outer. But of course that will depend on the welder's ability and where on the rim it's done.

Maybe for the rims that are stuck on the hub and need heat the tire should be removed from the rim first. Not easy, but doable.

That was quite a scary video as I have on several occasions heated a lug to help it release...even though you said it's not the same senerio as heating/welding a wheel (which I would not think of doing), I believe I'll figure out some other method of removing a lug if I run into that situation again. Many thanks...

We never applied heat to a wheel for a lug bolt...we'd just snap it off and replace it...(now I'm really glad we went that route.) - back when I was a wrench jockey

I have issues w/ fire near anything I want to keep....

Great video. I had no clue it'd do that.
