It is in fact great advice. here is why

3 Pressures all but guaranteed to be wrong
The pressure on the tire
The pressure the store put in
The pressure on the sticker

One pressure is right and that pressure is based on the weight the wheel is carrying.. So get it weighed.

Too much pressure and the tire does not fully engage the road. This can lead to loss of control and early tire wearout.

Too little and the sidewalls flex too much, also leads to loss of control and tire blowout.

Finally if the rig is overloaded he may need to either UPGRADE wheels or lose weight.. In my case I was able to upgrade tires.


Home is where I park it.

Plenty of ST tires are rated for more than 65 mph. Some of you are stuck in the 80's with towing technology, its getting a little annoying. My last trailer had Carlisle Radial Trail HD were rated to 81 mph. My current trailer has GY Endurance is rated to 87 mph. Just because they are ST doesn't mean max speed of 65 mph. Get over it. That said, I don't tow much faster than 68-69 mph because I can't afford the fuel it costs to travel that fast.

Most Chinese tires are under built, in my opinion. Pick up a generic ST tire, then pick up one of the tires I mentioned above. Significant weight difference. Having a tire designed to handle the weight (or much more weight) is ideal. Very few people know how much their trailer weighs. They are likely also running around on tires that are marginally acceptable for the weights. I always buy tires with spare carrying capacity and haven't had a problem yet.

Goodyear Marathon trailer tires are widely used in a variety of towable trailer applications and are designed and branded as “ST” (Special Trailer) tires. Goodyear Marathon Special Trailer tires, with the “ST” size designation, are speed rated at 65 MPH (105 km/h) under normal inflation and load conditions.

I finally got around to looking at the latest Escapee magazine. They have a help columnist in it and he was asked this question(paraphrased):
"We have a giant fiver with four slideouts. We drive six hours a day at 70 mph on the Interstates on GY Marathon tires. We had two blowouts in one day! What is our problem??"
Now looking at this I see two glaring issues myself but the help guy saw another third issue: get your fiver weighed. Now I admit that is general good advice but the fact that the Escapees seem to run a weighing operation may have crept into his thoughts.
What do you guys think, good advice or not.

Since Marathon tires are the subject and they are 65 MPH tires that were being used today, it shouldn't be annoying to anyone following the conversation.

The OP states that they are running "GY Marathon tires." Where do you get "cheap Chinese tires?"

Ask anyone that has run Marathons! I used to run Carlisles, never a blowout in. 14 years. And I towed at 70+mph.

As has been stated, the 65mph rating is dated and is now used as a blanket comment on any tire blowout thread.

More fuel for the fire:

The questioner in the article could just be that poor, unlucky fellow whose statistics ran out on him and he got 2 road hazards the same day. Been know to happen
