Don't forget to subtract your pin weight from the total weight. You're still a couple thousand pounds under. 75mph is also about as high a rating as you're going to get with a trailer tire. IMO, (and I'm a lead foot) 75mph is faster than I would travel anyway, regardless of speed limit.

Good to know. How do I figure the pin weight? And how much below the 14k capacity of the tires is a good buffer?

Best way to get your pin weight is on a scale.

Load it up like you use it and head to the local truck stop that has a scale of one you can se for free.

Axle it on and write it down.

Unhook trailer and weight the TV one axle at a time.

Subtract rear axle weight when unhooked from rear axle weight when hooked up.

That is what weight your unit adds to the rear of the truck.

I think you might be better off matching the tire load capacity to the axle rating. If you have 2 7000 axles you need tires that will support at least 3500lbs each. In 16" tires you will need to look to load range G to get any sort of buffer in capacity, and even then you wont get much.

If you have at least 3500lb capacity on tires and 7k axles you should be good to 14k plus the pin weight, or somewhere just north of 16k total. As it sits at 14,100, you probably have around 11,800 (figuring 2200 pin) sitting on the tires, rated at 14k total. G rated tires would give you more than your rated axle if you're looking for more of a buffer. E rated will generally fall in the range of 3500-3750lbs depending on manufacturer. The stock E tires on my Sierra were rated 3750 mounted on 6k axles and 14k loaded, 2300 pin.

So are you saying that you had problems with those? Are they one of the aforementioned bombs?

Unless you upgraded the tires on your order, you are pretty much guaranteed to have the cheapest tires the manufacturer could find at the time to put on your unit. All of them will be from some place in the Far East, and the chances you won't have a blowout will be slim to none, IMHO..

I had one pop on me last October and I have no way to know what caused it. I will say this, I have about 300 miles on the other 3 since the blowout (most of those driving the rest of the way home) and was surprised I didn't lose another one.
This is what it looked like:

I had no indication this was coming, TPMS started screaming out of no where and people honking at me in Atlanta. Fun times.
