The Towmax tires on this camper weigh about 1/2 of what the replacement Goodyear Marathon weighs that I replaced the Blowout with. I will block it up and carry in the tires to be replaced, because it started bouncing again about 5 miles from home, so another is about to blow out. I am only running about 2800 lbs per tire on LR E tires. These tires have about 3000 miles that were put on by me, I guess that when you look up Powerking Towmax at SaferCar.gov, there are many complaints on the Government website that detail just like mine.
You might consider doing a "Free Spin" inspection as seen in this YouTube video.

Kevinc2011,
If your rims are not rated for 110pai, then the G614's won't do you any good. If you are going that far, go to 17.5" wheels and 215/75R17.5" all position tires. These are LRH with a load rating of 4605#( I think). I wouldn't put a goodyear tire on a wheelbarrow let alone my RV, and I don't care how many years of engineering Tireman has, they are JUNK as bad as all the other China Bombs.
Frank

JIMNLIN,
I said the remark because every time I say anything about Goodyear tires being junk, tireman gives me all this technical data to say that it was my fault that the tires failed, when bottom line is they were china bombs like all the rest.

Any mention of China bombs and there is always someone to suggest that it is our fault. I've never experienced a blow out, but always check tire pressure before a trip and found bulges on my Carlisle tires in the process. 8,000 miles on my Maxxis 8008 with no issue. They are made in Thailand.

This tire was made in China. Driver stated that he had checked air pressure 50 miles prior to the "blowout".

Any comments or questions on why the tire failed?

air pressure. Tire likely leak down while driving. Bad valve stem? Seen many a one crack when adding air.

Can't be. It was made in China so that MUST be the reason for the failure.

Every time I check my tires, ( not every trip like some ), I spit on my finger and wipe it over the valve core. No bubble, put cap on.

you can see where the rim run on tire. It was mostly flat when failed. Most like this happen within 50 miles. Crack I referred to is where stem comes out of rim. If brittle and you add air it is subject to crack. Loose air going down road. Now I am not supporting ST tires. I won't run them. That tire was run on rim though. I only run steel valve stems.

I replaced the other three Powerkings with the Goodyear Marathon ST235/80R16 E tires. The 3 power kings all had the centers bowed out and they wobbled across the floor when they were rolled to the tire changer. The new tires that were mounted on my rims were flat across the tread surface and balanced easily. I am going to give these Marathon hires a try!

Did you file a complaint with NHTSA? We will never get an improvement in the products we buy for our RVs until manufacturers get real pressure. NHTSA can force a recall but they need data (many complaints) on their side before an investigation or action will ever be taken.

While complaints around the proverbial campfire i.e. RV forums , may make us feel better NHTSA does not follow forum conversations.
