Wow, such a long discussion over a tire off the rim. With a loaded fel and the tire deflated for whatever reason, driving on it will take the bead off the rim. Put it back on, check for leaks, and go on your way.

The stem is intact. Metal stem with threaded nut, metal cap too. New tire with too much chain traction on hard surface.

What's the difference between chains on ice and tires on dry pavement. The chains had absolutely nothing to do with it. I can wrinkle my rear tires back with the rim halfway to the ground pulling a root plow without breaking the bead, let alone dismounting the tire. Besides, as heavy as the snow may have been for that tractor, it is still a small tractor with small forces.

I hope you are right. The tire lost must have lost it's air somehow (that's still the mystery to me). I'm pretty darn sure that tire was delivered with 45 PSI only about a month ago. I sure didn't notice any difference in the tire inflation when mounting the chains.

I was probably working the tractor for a period of time with a flat and didn't even realize it. What puzzles me is what caused the tire to lose air. I think it had to be a "catastrophic" loss of air such as the bead breaking its seal or I would have noticed it sooner. I was working the tractor for about 1.5 hours before the tire came off. The photo actually shows the last little bit of snow/ice I had to finish. Where it happened on the level right next to our car garage and my tools was the best place this could have happened for ease of working on it. :laughing:

One thing is for sure I will be watching that front tire for any hint of deflation next time. I think, but hopefully not, there is an underlying root cause, such as a slight defect in the wheel or tire and it's gonna happen again.

Working in the wet some lube still present on the new tire beads may have re-constituted (absorbed water) and allowed the rim to break free.

I would think rubber on pavement is your highest traction condition i.e. the chains only improve traction on slick/soft surfaces.

I guess it's time for my curmudgeon side to come out .....

When I've had low pressure in a leaking front tire I've always noticed it in the steering. If the tire had a hole it would have leaked down again after being reset, same if the valve stem was bad. But I'll presume it hasn't. So if it was a low pressure issue it would have had to have been low in pressure from the date of in-service.

As mentioned, a relatively new tractor has not aged the tire bead to rim seal, and if you've mounted tires much, that is always a factor. I'll pull new tires off rims rather then older units. And as mentioned, the lube can be renewed with the snow moisture.
Still, how often do we experience or hear about new front tires pulling off rims when used on hard surfaces? I haven't.

During normal turning of a tire the sidewall deflects between the delta of the tread and rim angles, and those forces within can be significant when a load is applied. Just watch how our tires distort with a full bucket of gravel or soil. Normally they can handle that. But the cross links on the snow chains, and possibly the side chains, concentrate the forces in narrow bands rather then being distributed across the entire sidewall, not unlike a bead breaker on a tire machine. I would expect that to occur when the chain is no longer separated from the asphalt by a layer of ice.

Very good discription of what might have happened,,:thumbsup:

So the chains caused it, but they also had nothing to do with it. :confused2: :confused2:

I think I take the above quote and hope for the best. Thanks to all !!!

How do you take out of that that they had nothing to do with it?

This quote below ... I'm getting mixed opinions that is all. Thanks for your post !!!
