Speed and blown tires

Another thought I had while driving home today again from our holiday camping trip up north. I posted about driving to fast and not surprisingly I was told I was going to fast at 68mph even though I was the slow one on the road. So this weekends trip (560 miles round trip) I set it to 65mph per good advise here on the boards ;) and of course all (dozens) but two rv's (who kept pace with me) passed me anywhere from 66mph to i'm guessing 80mph. so my fuzzy math is telling me that 95% of the rv's, boats, jet ski's, etc were going above or well above 65mph. This was also true of my last trip of 700 miles.

So here is the question, I know the Chinese tires have a bad rap and I know they are of low quality. But how much of the problem do you think is because of simply going to fast for the tire? How many of you who travel under 65mph (where are you guys btw?) have had blowouts?

  • Don't kid yourself, junk off-shore tires are the cause of the great majority of trailer tire failures.
    For years I used Carlisle Bias-ply tires on my old TT and thought all this talk about bad tires was probably caused by the operators.
    Then I got my first set of Radials and found out the truth. Even with doing everything right (weight, pressure, speed), I had all kinds of failures with those new Carlisel radials - one had a tread seperation just LAYING IN THE BACK OF MY TRUCK under the canopy! Of that first set of five, all failed one way or another. The next set saw a couple more fail.
    Then I started using a better tire (Maxxis) and the failures ended.
  • IdaD, I shopped around for 75mph rated tires, even though I tow at 65 mph. Though, have been known to coast up to that 75+ mark on a looong, straight downhill. I like the insurance of the higher speed rating!

    And... I'm running Contential HTL2's! Before someone asks! ;)
  • My Provider ST215/75R14 Radial Trailer Tires LR D are rated at 81 mph ("M") but I never run them that fast. I'm the guy driving 55, and 58 downhill in California. Yup, let them pass me...I'm on vacation!

    I believe age, speed, inflation, temperature, road hazards (glass, nails etc.) and damage from hitting something (campsite rocks, wood etc.) have the most to do with failure.
  • We keep between 63-67 mph mainly for the fuel consumption. We are also on vacation so what's the rush, other drivers can go around.

    How do you know? Please share the study or studies that you have.


    Bad generalization on my part. There are some good ones, I'm thinking of towmax which is popular with manufacturers.

  • Made the short trip to daytona for the races this past week, I try to keep it around 60(so there's a few of us) and like you getting past by most
  • My tires are rated to go 75 and I'll tow up to that speed. I do keep an eye on my pressures and I have pretty new tires. I don't feel like that's an unsafe speed with my setup as long as conditions allow for it. We have wide open highways out west and long distances to cover so I'm not going to dink along at 65 mph.
  • I think 90% of tire blowouts are caused by ignorant people not following the directions. Forget the fact it's made in china, tire pressure, and tire speed ratings are IMO the number one cause of pre-mature wear and blowouts, hands down.
