Tire blow out.



I bought 4 of these and ran them for 250 miles and so far so good. They are Chinese and I am starting to get concerned. My tt called for a load c and these are load d so I hope that I should be ok since I am under stressing them and I tow about 5000lbs loaded

OK. I was getting rather frustrated there.

Can you let me know what you need to know. I posted a few pictures that show wheel damage, evidence of impact and the results of a tire hitting some object. Sometimes tires go into a pothole and "hit" the opposite side of the hole after dropping part way into the hole. Tires can also hit road trash. I think we have all seen a variety of stuff from mufflers to brake shoes to 4x4 lumber.
Sometimes the object being hit has a sharp edge that can cut the tire. Other times the rapid impact can simply over-deflect the tire as it tries to mold itself around the object.
Sometime the tire manages to bend in the milliseconds allowed by the vehicle speed. Other times the tire can't move/bend fast enough.

Shock Load. Think of entering a swimming pool. You can walk in down the steps. You can jump in from side of the pool or you can jump off a high diving board. Each of the above are at a different speed. The faster you enter the less likely it is for the water to move and mold itself to your body. Fast enough and you might even kill yourself. Clearly speed is a significant factor.

Need more?

You said nothing about your inflation pressure. ST205/75R15 LR-C are rated 1,820#max @ 50 psi and 2,150# @ 65.

Wonder how you know your weight is 5,000# on the 4 tires. DO you have a weight slip?
Very few RVs are 50/50 axle to axle split and also very few axles are 50/50 side to side.
Many are more like 47/53 or even 45/55 so it is possible that one tire has 5,000 x .55 x .55 or one tire at 1,512#.


250 miles is not a real evaluation. The tires are really just broken in.

Wow, didn't know my post would roll like this. Very interesting. So what did my tire do? I'm sure I've hit things, nothing I was aware of when this happened.

Tireman: He said he bought 4 of these, so I would "assume" that if he's pulling 5000 lbs, then each should be supporting 1250 lbs, ignoring any weight split. I would hope any weight split he has wouldn't take him over the 1820 lbs at 50 psi (or the 2150 lbs at 65 psi). That would be quite a split if it does.

Also, as I've mentioned before, most RV owners have NO CLUE what's happened to their tires before they drove it off the dealers lot. Just today I was behind a guy with a TT on a flat bed, pulling another TT. He was doing at least 72 mph (probably for the last 250 miles from Indiana!). So if you bought the TT on the flatbed, lucky you. But if you bought the one being towed, NOT so lucky you!

Need better pictures. Full sunlight is best. Good camera with sharp focus (4MP or better and close enough for only 1/2 tire per picture.
Big area of concern would be about 6 - 9 oclock as seen in your original picture.
May be best to email pictures direct to me rather than posting as Forum cuts quality down.
I can post result of my "inspection" if you like.

I'm running much higher weights, but I saw up to a 500 lb. split between tires.

I can't imagine a lighter unit would see a such a swing, but it can be pretty surprising how far of difference that there can be. Especially when you don't see it by weighing the axles. I only saw it when I did the individual wheel weights with Escapees.

There is always going to be different weights on each tire. What rockfordroo was trying to point out is that the poster has A LOT of leeway to absorb the difference. Enough to absorb even a 500 lb difference and and still have a good leeway after that. Tireman needs to get a grip sometimes and recognize the obvious before writing what I deemed to be a derogatory post.

No one can say for sure what any tire will do. Be it for a car, truck or trailer. When I start seeing multiple trailers strewn along roadside maybe I would worry a little bit. So far in 22,000 towing miles on my two sets of China tires I have seen 3 trailers along the highway with flat tires. If China tires were really so bad the RV industry would not be allowed to sell them. Maybe you or I will get a flat tomorrow, who knows, but I am not going to fret over it. Upgrading load range (like you did) is the best thing you can do in my opinion.
