Towmax Tires

Towmax Tires

I have Tow Max ST225/75R-15 tires, Dot code year 2007, pulling a 28ft 5th wheel trailer. I am aircraft mechanic, the tires had good tread and tires properly inflated, I drive @55mph to keep tires cool, and do not exceed speed rating of these tires and cover the tires when stored to prevent deterioration.

I had 2-tires blow out at different times, it caused a lot of damage to the r/h rear quarter panel of the trailer, lots of lost time and dollars to fix.

You're looking for trouble with these tires.



Editorial Comment:
I've seen tires similar to these listed as Boat Trailer tires.

I don't know if these are the same as what you used, but if they are the same you might be facing a weight issue. By this, I mean if your 5th wheeler weighs more than what these tires are designed to carry, that is the cause of your problems rather than a faulty product.

Check the load capacity of these tires which you will likely find stamped on the sidewall, and compare this to the weight of your trailer. If you are not within the maximum the tire will carry, that would cause the failures you discribed.

starstarstarstarstar 		Power King Towmax TROUBLE
by: Ray

I have a 2010 Keystone Everest 5th wheel with Power King Towmax ST235/80R16 tires. They came as standard equipment with the trailer when I bought it new in 2010. I have less than 4000 miles on the rv. I keep the tires at the recommended psi as per side wall and use tire covers when not in use. I only carry food in the frig., cloths in the closet and pet stuff and two chairs in the under compartment. I never exceed 65mph. I also check for heat on all four at every stop. Just had a blow out on the Pa. Turnpike that took out the side of the rv. The tread came off the tire in strips. I will do my homework on finding replacement tires. I would never trust Power King. Run the DOT tire code online before buying any tires. It will tell you if a brand is coming out of the same plant that made the Power King. The Chinaman doesn't care what happens to your rv or your loved ones!!!!!

Editorial Comment:

You may have caused your own problem through misunderstanding the tire pressure which is stamped on the side of the tire.
Look closely at what is printed there. It will say something like "Maximum Pressure", which means that the tire should never be inflated beyond that level when measured cold.
The Maximum pressure is very seldom the best or recommended pressure for any vehicle. In most cases using the maximum pressure will result in your tire being overinflated and over inflated tires will not wear at the normal rate.
Your vehicle should carry the pressure which is adequate for the load you are carrying and if the weight you carry changes from time to time you should be increasing or reducing the air pressure to compensate.

I have a 2010 Keystone Raptor 300MP with Towmax tires. I check tire pressure when they are cold, don't pull overweight, and don't hit curbs and had a tire blow while driving down the highway at 60 mph (To keep the tires cool.). Don't see where this could be my fault. I have seen way too many posts about the Towmax tires being defective to think this is always the owner's fault. It is also nice to know they back up the tires with the posted warranty. I will be buying LT tires in the future, they seem to hold up much better!

by: Charles Bavier

I bought two new tires for my boat trailer and after just 60 miles maximum I had one blow out at 45 MPH. I almost lost my pontoon when the tire blew. The tires are 5.70x8 rated C or 6 ply and for 910 Lbs each. My pontoon and trailer only weigh 1600 Lbs. I cannot find the web site for Power king as I feel they should send me a new tire. I still have the blown tire and ruined wheel. My advice is stay away from Power King. I cannot find the receipt for the tires but the dealer told me there is no warranty on trailer tires. I am really afraid to tow the pontoon again with the power king tires on it.

The tires came on our 06 United Exspressline 28ft Super Hauler (enclosed car hauler). Mileage I’m not sure of as we started pulling it with a dually truck for the first 2 years and then when to a diesel motorhome, but it’s a bunch. We run all over the country and rarely at speeds under 70. This past weekend was the first time I’ve ever had a problem with the tires. One of them looks like it’s got a cord that let go in the tread area that fortunately my wife and son saw when we were stopped at rest area before it let go completely. After 5 years of hard us I think they have held up pretty well.

starstarstar 		Had a blowout myself
by: Mark

I had a set of these on my trailer, less than a year old, less than 200 miles on them, and hauling a boat that has a total weight of approximately 7,500 lbs inclusive of the trailer. I recall that each tire had a load rating of 2650 lbs each, which adds up to about 10,600 lbs = 70% capacity. With proper inflation, conservative speeds and so forth I thought I was safe. One tire shredded while driving at 55mph on a highway, however I can't be absolutely certain that I didn't hit something on the road. I don't think I did because my truck tires are right inline with the trailer and I didn't feel anything.

To be safe, I upgraded to a 9-ply trailer tire.



Editorial Comment:

The fact that your tire shredded suggests that it blewout after having suffered structural damage produced by overheating probably caused by driving with low pressure.

I'm not suggesting that you weren't careful in checking the pressure, but suppose, while you were driving you ran over something which caused a slow leak. That slow leak results in a lowered pressure while you're driving down the highway ... the tire heats up and ... pow!

This could happen even with increased plies, although the chances of having the exact same circumstances repeat themselves are pretty slim.

by: Anonymous

if i was towing a trailer be it an RV fifth wheeler or travel trailer i would check tire pressure before i hit the open raod,
these are great tires and i am happy with the wear i have had to date and the performance.
any tire may blow out and it is quite presumptious to assume it is the tires fault.
check alignment and pressure and also stay away from the curbs.
