Increased load and higher driving speeds both tend to cause tires to run hotter, and it is possible that this combination of factors has led to your two recent blowouts. A higher load range tire can deal with the increase in your trailer weight. However, most trailer tires are rated for only 65-mph unless specifically stated otherwise. None of our tires in your size carry a higher speed rating.

In your tire size we offer a tire only, Kenda Bias Ply Load Range C tire # AM10004, and also pre-mounted tires/wheels in your 4-on-4 bolt pattern like # AM30040. This white wheel/tire combo offers a weight capacity of 745-lbs at 90-psi pressure. You can see all options on the linked page.

None of these tires is rated for speeds higher than 65-mph, so you'll want to be sure to always have them inflated to their recommended cold tire pressure and operate them within their rated capacity to help avoid heat-related blowouts in the future.
