Have read bazillions of threads in many forums about trailer tire failures, and have come to the following conclusions:

There are low quality, low priced tires out there. Unfortunately a lot of them are OEM tires on many brands of towables. Counterpoint to that, I have read an equal number of threads about folks wanting to wring the maximum discount out the sale price of the RV they wish to purchase. Something has to give somewhere..........

OTOH: Tires like axles and suspension are sort of important. I get the impression manufacturers will install the bare minimum required to move the whole assembly down the road. I read/hear all this talk of "extra margin". What exactly is that in quantifiable terms and can it be proven by anyone? For example, Our WhiteHawk rides on 3500 lb. capacity Dexter axles with 205/75R 14 Load Range C tires, rated at 1760 lbs. each at 50 psi. By my cypherin' each axle's tire set provides a "margin" of 40 lbs load bearing capacity in excess of the axle rating. Is that enough, once I start throwing my stuff in the trailer? Is that enough to withstand the "dynamic" forces acting on the tire as it bounces down the highways and byways? Then there's the speed question. Who needs to drag a trailer down the highway at 75 mph? With the exception of a few Western Interstates, I don't know of anywhere in the country that's legal. Not to mention the faster one rolls, the more heat generated by the tire and sooner or later.........POP! goes the weasel! Witnessed that first hand 5 years ago towing our new to us fifth wheel home from California. Two pickups both hauling fifth wheels blasted past us on I-8 in the Imperial Valley area. We were rolling along at 65 mph (our trailer had GY 614's on it), they were going...., well faster than us. 15 or so miles up the road we passed both them; both suffered tire blowouts on their trailers. One of them had a nice slice out the sidewall behind the wheel well, the other had a bunch of wire and plumbing hanging out of its belly and good bit of the tire neatly wrapped around the trailing axle.

Maybe it's tire quality maybe it ain't. But I'm inclined to think loading, speed, & maintenance have a lot more to do with tire failure, regardless of country of manufacturer, than people want to acknowledge or admit. Again, I grant there are some sad tires out there, but (knock on wood) I have yet to experience a tire problem on either trailer we owned.

X2. Agree with all you said. Particularly why anyone needs to run @ 75mph. Camping is supposed to be lesiurely and fun. Why risk your whole trip, your family's safety, and that of others on the road, all just to arrive at the CG 10 minutes sooner ? If you get there at all.

As for me and my family - we're content with traveling safely at 60. If we want to arrive sooner, we just leave earlier. JMHO

Go on any highway in California between the Glamis Dunes and LA or San Diego and you will see trailers being towed at 75+. I am sure the rest of Calif is the same but that is where I winter..

I live and tow in California, no way do I or will I tow at 75. In fact I rarely even tow at 65.
