What does toilet paper have to do with any of this????

 

I always carry two spares AND my big floor jack. My trailer has a GVW of 9990lb but recently I found out that it could tip the scales at about 17500lb and still be fine as long as I didn't get out on the highway. I learned my lesson once on the highway when I ended up losing three tires before I finally decided that E-Rated radials would be a better way to go than the stock D-rated. You can read all about it if you check the threads I have started...

 

Might want to check the axle alignment and could be they are scrubbing and wearing the tires funny.

For that small of a load Load range "C" tires would have been adequate, shouldn't have blown out "D" or "E". No way was it overloaded.

How fast were you going? Did you check the pressures before heading out?

Maybe you were just unlucky and picked up another nail or something and it went flat then blew. I really cann't see a "D" tire blowing out with that load unless it was low on air or got hot from going too fast....

 

I have D load range on my 24' enclosed trailer,it gross when fully loaded with car,golf cart,generator, tools is around 8,800 lbs it does OK. But I have found some load rang E tires and plan on upgrading soon.I think a lot has to do with valve stems I have the metal stems.
And Dave looks like the car has a flat also.

 

Match the tire to the load. Pressure, load and sidewall stiffness are all a balance for performance and longevity. Premium tires are always best.

 

I have changed a 235/85/16 Goodyear 5er tire. I carry a 40k bottle jack and 4 way tire wrench. I was 45 M SW of Houston & Good Sam was going to be about 90 minutes, so, I just got after it These tires with steel wheels weigh about 100lbs, not for the faint of heart.
I started carring a 12k bottle jack when I tow my 12k utility trailer. It came with LT7.50x16 bias tires that have performed very well. I think the bias tires hold up better to long periods of sitting, as trailers often do. They are at least 5 years old & have a spare, of course.
I put Bearing Buddies on the trailer with the special neoprene? seals for the brake axale, which in theory keeps the grease out of the brakes. So far, so good. I grease up the buddy bearings each trip. You can get the special seals on bearing buddies web site
Running any trailer is like a crap shoot. Sooner or later, a tire is going to fail.
For what it is worth, I try not to exceed 65 with the utility & 55 with the fiver. It is safer and nets better mileage. I always check pressure & run the max.
If you are driving less than 200 miles, 55 will cost you 30 minutes, in exchange for 2-4 mpg. You cab set the cruise and seldom touch it. I do get over where I can on 2 lane roads, if traffic builds.
