By my observations, regarding tires in the automobile spectrum, perhaps Light Truck tires would be better than high-speed-rated tires.
High-performance passenger- and sport-car tires are rated for maximum safe speed, identified by a letter preceding the routine "R" for "radial". The further out in the alphabet, the faster the tire may be safely driven. "VR" is quite fast. "ZR" is even faster, somewhere north of 150 MPH.
Tire identification works as follows:
Let's use the tires on your little commuter car as example; P185/60R15.
P = passenger car tire.
185 = width of the tire in millimeters.
60 = height of the side-wall in percentage of the width, known as "profile".
R = radial construction tire -- all cars and light trucks these days.
15 = diameter of the rim.
I went out in the garage and looked at my brother's sports car. It has the very latest super-duper extra-expensive "two-hundred-mile-n-hour" ZR-rated tires; 275/40Z
R17. But the weight rating does not impress me -- only 1,650 pounds. Yes, ridiculously low profile, as Gyre pointed out.
My pickup-truck is a different story. These tires have no speed rating at all. (Technically they are rated somewhere in the middle of the alphabet, but nobody cares since sensible people do not drive a pickup-truck particularly fast.) Instead, these tires are built for heavy loads, and are identified by the letters "LT" for Light Truck, at the beginning of the identification number; LT
225/75R16. These tires are rated for 2680 pounds.
Finally, trailer tires. Many of these are of pre-radial construction, since the old-school design is stiffer and thus keeps the trailer more stable behind you. Pre-radial tires are known as Diagonal, or Bias Ply.
So here I have some ST205/75D15. I don't know what the S stands for, but the T stands for Trailer. And D for Diagonal. Strangely enough, these are weight rated for only 1820 pounds. But trailer tires come in many flavors. I have others who are so old-school (though brand new) that they do not even have modern identification numbers. They even take weird rims. But they are rated for 2790 pounds. Although that's not much more than my Light Truck tires.
Of course, I am comparing apples and oranges here -- various sizes that I just happen to have handy. But you can find specifications for every tire on Earth on the interweb.
Bottom line, so far as it goes, for tires in sizes for automobiles and up, I'm thinking Light Truck -- and heavy truck, of course. And for dawg's sake, use fairly new ones.
Oh.... Golf cart tires? All right, let's go back outside, this time to the barn. And... the tiny tires on Lady Sophia do not even have a weight rating. They are not even allowed for highway use. And they have a maximum inflation pressure of 22 PSI, which is deep in pipsqueak territory.
The tires on Millicent The Bus are 295/75R22.5 and can carry 6175 pounds. Yes, these are 18-wheeler tires.
