I had a tire blow out on my tandem axle trailer today. I was driving about 70 on the interstate. I didn't know it until another car pulled next to me and told me.

I used my "Trailer Aid" which I have used a couple times before and I love it:

So, how fast do you guys drive with your trailer? I think my tires are rated for 70mph but now I want to look again.

Thank you for adding the link to that ramp on Amazon, I just ordered one for myself.
Sorry you had the blow out and trouble...

I like that little ramp after using it 3 times this year. It's lightweight and compact. The only tricky part is getting in your truck and "feeling" when your good tire is up on the ramp. The first time I used it I had to go back and forth a few times to get it positioned correctly.

This blowout looks ugly and it could have been disastrous. I really think the tandem axle saved me.

How old was that tire ?

Very few "Special Purpose" (i.e., trailer) tires are rated for 70 MPH.

Bought the boat/trailer new back in January. Probably had no more than 5000 miles on it.

I looked up the rating on the manufacturers website when I first got it and I could have sworn it said 70 but now I'll be checking again.

Is there a general rule of thumb you guys use for maximum speed with bass boat trailers?

I remember Goodyear used to recommend increasing the tires max psi by 10psi if it was being used between 65-75mph

I can't believe that fiberglass fender survived the blowout. Just a suggestion but I would check the age of the other tires. Mileage isn't that big a factor with trailer tires because the average fisherman will not pull his boat enough to wear the tread out. If the tires are over 5 yrs old you might think about replacing them. Yes, the tandem axle helped your situation.

ST tires are rated for 65MPH.
I also run tires on all of my vehicles and trailers at max cold pressure. It puts less rubber on the road, less friction, and the tires run cooler.

Daggumit Toofy, sorry you had that happen. Looks like it seperate s & thank goodness it didn't tear up that fender. I will run 70 some but mainly 60-65. I know some guys that 70 is about the slowest they run. Yes they have more tire issues. The only tires I've had issue with were older ties that separated just like that. Tread separated from tire. Be safe out there.

Heat is the enemy of trailer tires. Air is your friend. Make sure tires are inflated to maximum cold pressure.

He's correct. So is another post stating that age alone is a factor. Several manufacturers have specifications stating a rather short lifespan for SP tires, regardless of mileage or remaining tread. This circumstance started getting bad when all the SP tire manufacturing moved to China a number of years ago. It seems the formulation they use for the tire carcass is just like a lot of other stuff they make - cr@p.

For those who have inquiring minds that may wonder "What does air have to do with heat?":

With higher tire pressure, the tire "squats" less on the road. In a given moment, that squat is a distortion in the tire's shape at a given spot. But, your tire rolls very fast, so the location of that spot on the tire where the tire shape is distorted changes constantly. Pick a spot on the tire, any spot. Now follow what happens to that spot. Every time it rolls onto the road, it flexes, creating heat. Every time it rolls off the road again, it flexes yet again. This never stops, and it happens constantly to every bit of the tire around it's circumference.

With lower tire pressure, the tire flex is more pronounced, and the tire heats up even more. This is why Goodyear recommends running higher pressure in their trailer tires if you are going to drive higher speeds. The faster you go, the hotter any tire will get. The most direct way to negate this is by adding more air to make the tire "harder" so it distorts less as it rolls.

So I just looked up the tire on the manufacturers website. Scrolling down the list, it's item #170035

It has a "T" speed rating which is up to 118mph according to this:

Now I'm even more confused.
