Tires condition

No weather cracking from 99. Wheels may break off though. LOL

Not on the sidewalls, but don’t forget to look in the gaps in the tread. Cracking can be real common there and sometimes goes overlooked.
(not sayin yours are)

Look a little rusty

Hard to make out the brand name on the sidewalls but they look to be 'China Bombs' to me.

Those are 100% genuine 'China Bombs' Rims look like they were in the last war.... and lost.

I read an article that the Russian military is stalled in a lot of places in Ukraine because the vehicles were running China bomb tires that failed.

I read an article that the Russian military is stalled in a lot of places in Ukraine because the vehicles were running China boob tires that failed.

I read that too somewhere, maybe on Rumble, I don't remember. Do know one thing, RV Builders love to mount China Bombs on new RV's and they seem to explode regularly.

Something about the makeup of Chinese rubber causes it to degrade quickly. Why I won't ever buy rubber tarp straps at Harbor Freight. In less than a year they dry out and break.

Always at least one thread on the RV forum I infrequently frequent about them exploding and ripping off fender skirts or worse. Seen some real carnage picture on there too.

Your cut isn’t going to have a catastrophic explosion on the freeway at 80 mph. You will just start getting flats. Annoying but not dangerous. You can also get a little more use out of them by tubing the tires.

They are tubbed but also filled so flats would be problematic.
However, so far so good.
Just very frustrating as it cost me fair $$'s to install new tires that went as bad as those replaced and that within 5 months.
LOL, top speed, flat out, is all of under 10 MPH.
Just very frustrating! Had I known I'd have kept the old ones and saved many $$'s.

While it was a fight, I did get some partial compensation as warranty was still valid, they wanted the defective tires back but could not provide replacements so was I to ride on rims?
That was Goodrich, finally owned by Michelin with a few in between.

I have only has to replace one set of tractor tires due to thorns embedded everywhere. I bought the replacements at a tire company that specializes in heavy truck and equipment tires. I don’t remember the brand but they lasted over ten years and were still good when I sold that tractor a few months ago.

My tires on dump trailer are old... Take a look and tell me if they still usable. Appreciate your inputView attachment 736480

Surprised they hold air. Check date code. Over 5 years, replace regardless of tread.

If the ran since ‘99, theyd hardly be considered “bombs“.

That advise sounds expensive.

And still working. Highway and all. Never removed tires or wheels since new in 99!

 

[Hoho223]

Great tread. Give it a shot with 2 tons of stone in the trailer. Wire brush some of that sunburned skin off.

I assume you are referring to my pic?
Yeah, 2 tons of stone is the same as 2 tons of feathers, LOL.
But my trailer is axle-limited to just over 1 ton. And I used to push that sometimes.

I'm thinking they purposely add air or pin holes so that they will always leak, perhaps to encourage the sales of innertubes.

But their tubes leak too.....

 

[HighTwelve]

I assume that you don’t take the trailer on the highway. I live in PA too and no shop doing state inspections would pass those tires. I have been pi&&ed off more than once when tires were failed because of cracks between the tread ridges that didn’t look bad to me at all. Another excuse to sell a Chinese “trailer use only” tire.

As to why the tires crack has to do with sunlight and ozone degradation of the rubber. Yes, tires used to go for many more years without cracking. The reason for the cracks is formulation changes in the rubber used to make the tires. I’m a retired chemist, although not a rubber chemist, and my guess is that additives that used to be put in the rubber to counter the effects of sunlight and ozone are now banned.

The cheapest things in a rubber formulation for tires are going to be carbon black and silica. The chemicals added to get the rubber to link together (vulcanization) and harden and resist ozone and so on are going to be the most expensive. No wonder that the cheap trailer use only Chinese tires wear out fast and develop cracks. They just scrimp on the chemicals used in well made tires.

Which also come from China... and they stink too.

 

[PILOON]

The primary component to prevent tire checking is plain carbon as discovered by Mr Biney and Mr Smith* and thus making then very wealthy.
Carbon black is also one of the cheapest pigments so why dilute or substitute it.

Another 'factoid', carbon black also blocks or hinders RF energy, like don't paint a radome with a carbon pigment based paint.

* Biney & Smith are the Crayola Crayon people with whom I worked as a rep for many years, (good times).
