We just returned from a trip to the smokie mountains. We had a great time until we had a blow out on our Grand Junction traveling home. We bought our GJ in May of 2007 NEW. We can not have over 8,000 miles total on the tires. As I said one blew out and after inspection we two more had serious belt seperation. So I had to go ahead and replace those as well so we could make a safe trip home. After calling the dealer, where I purchased our GJ, I have not gotten very much help. Our tires are ST235/80R 16 Power Kings Powermax. They are 10 ply tires with an E rating. I can not find out who makes them and I have been told they are usually very good tires. My bill to replace them, by road service, was almost $1000.00. Not counting the repair I am having to have done the GJ that the blown out tire caused. Does anyone know who I could talk to concerning the warranty on these tires? Thanks in advance for any information you could give me.
I had Karrier Load Star 10 plys on ours from the factory. Left Missouri and everything looked fine, when we arrived in Arkansas 2 hours later one had a bubble in it. Bought a new tire for the spare and had the spare mounted. The other 3 looked great. Pulled home 10 hours and noticed the others appeared fine but to be safe I replaced all of them with 14 ply tires. When I brought it to my tire guy, they pointed out that the threads had shifted on the 3 old ones.
My wife researched and found Karrier. They had me take lots of pictures, measure the thread depth and cut out the DOT numbers and send everything to them. They said they would either ship me a new set or pay up to $100 depending on wear for each of the 5 tires. Waiting to hear back from them on our case. Luckly all this took place while I still had the old tires.
Hi Carlos, I google power king powermax, and they are made in China. The google site even brings you back to rv.net where there is a disscussion on these tires. Your probably out of luck on any reimbursement, but do a seach here on rv.net and see what you can find. John

We have had Power King on our Cruiser since 2004. No problems yet but this is a good heads up. I have had them all over the country. Did you check the date they were made and make sure they are under 6 years old? There are no rules so you could get 6 year old tires from the get go.
Our R8 19.5 tires are make in the USA and date from 2002. I looked them up once and then they are actually make by like Brigstone, Kelly-Springfield or some known source but I failed to note it in the MH Docs.
When we rotated them last month while they were off of the MH we washed each one with soap and water and gave it a detailed inspection and they looked like new. They had been covered until one year ago and now have 19K miles on them but they are at the point where they require a detailed annual inspection.
This thread does highlight my thoughts that most blow outs occur in the first 5 years instead of the last 5 years of a truck tire life span.

I think there are two reasons some people have tire problems.
One is that most of the ST tires are speed rated at 62 MPH and the other is that some people will not weigh their set ups and wind up overloading the tires.
Most people want to keep up with traffic when towing and will drive between 65 and 70 or even faster, and do so for hours at a time. Most ST tires are only speed rated for 62 MPH max. and could blow from excessive heat when driving at 65-75.
Others will load their trailers with all the "stuff" they want to take and because they don't weigh their set ups, wind up overloading the tires, this could also happen if you are using LT tires.
I also think you should switch from the ST tire to the LT tire IF you can find one in your size.
The LT tire is rated at 75 MPH and gives a greater safety margin when driving at higher speeds.
Most of the heavier trailers will come from the manufacturer with LT tires that are speed rated at 75 MPH.
If you want to find out the who, what, when & where about your tires, go to this site and follow the directions, you can find out where your tires were made.
The last four numbers in the DOT code (only on one side of the tire) is the week and year the tires were made, (2207 would be the 22nd week of 2007) If you have a three digit code the tires were made before 2000.
Most tire people will tell you to use Michelin XPS Rib tires if you can get them in your size. These tires seem to be the best you can get, but, I like the Goodyear tires just as well. The main thing to consider is to switch from the ST tire to the LT tire and you can do it easily because you already have 16" wheels and "E" rated tires.
Also it seems that tires not made in the USA don't last long.

YES you can find the appropriate size in XPS Ribs - use a size calculator avail on many internet sites. It will give you the dimensions of your existing tires vs new tires. (You will have to go to 235/85 -or to- 245/75).
Check the psi rating of your rims (usually on back of rim). XPS require 80 psi.
Do a search on here for Goodyear Tires (failures!) *NO* comparison to XPS Ribs!
Also - many GY are now made in China. You might as well have the Power Kings!

I purchased a set of "TOWMAX" 10 ply "E" rated tires by POWER KING last summer and have put approx 10K miles on them. So far so good. In fact they still look brand new. They replaced a set of useless Goodyear "Marathon" 6 ply "D" rated tires. These had 25K miles on them and were completely shot and leaking!! The Power Kings seem to do the trick........................
Wow! How timely this thread is! I to have a Grand Junction with the same size, (rather rare size I might add)Power King tires. They are original equipment with about 10,000 miles on them. The trailer was new in January 05. I started out on a very long trip leaving from Washington state, and going 1st to Oakland to do some work there. When I got there, I noticed two of the tires, one the front axle, the other on the rear on opposite sides were bulging on the tread all the way around. The plies had seperated. This was about three and a half weeks ago. We replaced these two tires and put the replacements on the rear. We had a tough time finding this size trailer tire, as they are rather rare. Since then we have traveled down to do more work in San Diego, and then across to Dallas. Yesterday one of the remaining Power Kings blew out about 4 hours west of Dallas in the 106 degree heat. I am now sitting in Dallas waiting for three replacement tires, an extra to go on the spare. I would not buy a pair of these ever again. I know that heat causes tires to go bad, but man! I was lucky. It didn't do very much damage except wraping around the axle twice. It took an hour and a half to get it cut loose. Lots of fun!

On our first trip to Florida in March of 2005, we had two of our RV tires go bad. We replaced all four tires with POWER KING LT235/85R16 tires. These tires are 10 ply 'E' range and made in USA. The tires are still good after 15000 miles on them.
