Trailer sidewall

I have built a rollover trailer to train firefighters on animal extraction.

The first time we rolled it, I blew a tire (separated from the rim). On subsequent rollovers, we upped the tire pressure to max recommended and that helped. However, when we roll on harder surfaces, the tires are stressed and want to separate from the rim.

My question is would a stronger sidewall help? Stronger sidewall is a higher ply rating, correct?

Thanks.
 
Agree. No need to make a repair job each training session. One is not likely to need the tires to be compliant.

Would an innertube keep the tire seated on the bead?

Do the trailer tires have the safety rim, not the easy to unseat farm rim?

If you would get bias tires you won't have any problem. I've had radial tires blow out just going around a corner a little too fast.
 
agree also. and dont need new tires , just get good used from from behind the tire shop.

I highly agree with this. You can get an assortment of rim sizes that will fit your trailer's bolt pattern, then get old tires for free. Then if the tires start burning during the exercise, keep the realism going and let 'em burn (check to see if you need clean air permits of some kind). Would be a good way to use old tires that are destined for the landfill.

Another idea would be to make fake tires out of steel, then simply screw pieces of old tires to the steel for the realism of rubber. The steel would last forever if constructed well enough, and there would be no more searching for the correct tire sizes - just cut from any tires you can get your hands on.

Wow!!! Despite all the research and testing by all of the tire companies before putting the radials into production?
 
I don't know if this will help you, but have you looked at beadlockers? Wheels with beadlockers are pretty expensive but they make a kit for DIY for $120 per wheel. Check out XO-Fab.
 
x2 on tubes, or bias tires. Retired Career Firefighter and back with the rural volunteer dept. that I started with. Interested in hearing more about your project. I have been in a class given by a County agent about handling farm animals at accident scenes. This person tried but did not appear to have experience working with stressed animals. When I started as a Volunteer Firefighter in 1980 there were several farmers on the department. We have 2 Dairy Farmers now, and one is so busy with his farm that he rarely is able to be at training. My Uncle was a Volunteer on the Rochester Fire Dept. in Racine County. There was a scanner on a table in the house. If a fire call went out, someone from the house would go to barn or field to get him. Remember during the 60's spending time on the farm and seeing him put on his hip boots and coat and take off to a fire.
 
Some demolition derby cars and off-road dirt bikes have self tapping screws or wood screws through the rim into the tire bead to keep the tire bead seated on the rim and to prevent tires from spinning on the rim.

And they probably have tubes in them.

Tires are undersized for when most of the trailer weight is transferred to only one side .

From what I'm seeing, many derby drivers are now using skidsteer tires.

Does this trailer need to be roadworthy? If it needs to be roadworthy, then most of the suggestions aren't practical.

The reason the beads are coming off is because the tire is undersized for the load. You need tires rated for about 2X the load rating that you currently have, which consequently, will have thicker sidewalls, so in a roundabout way the answer to your question is YES!
 

Have you considered some type of out rigger that you can extend out and down to take the weight of the trailer off the tires
Maybe a couple hitch receivers you can slide a square tube in with a small tire and wheel attached to the side of the tube
