Tire questions
My trailer tires ST205/75R14 say max load at 50 PSI, the trailer sticker says max psi 50. The wheels (Sendel machined aluminum are max 60 PSI). The new Goodyear Endurance trailer tires are max load ...

So after the tire size is a weight and speed rating. This lets you know what the weight limit is and what speed the tire is rated to. I have an old Mercedes and it has weight/speed rated tires of 91H (following the size). The 91 weight rating means it will carry 1356 lbs and the H speed rating means it is rated to 130 mph (at the max pressure). Now just because my tires are rated for 5424 lbs and 130 mph doesn't give me the green light to pile in 57 lead weights and go 130 mph. After all the car only has a GVWR of 4200 lbs and the speed limits are way lower also. So what I am saying is a tire that was sized for your trailer may not have a hugely high load and speed rating, but it may be perfect for your equipment. A tire rated for twice as fast as you want to go and one that will take twice as much load as you need will go flat just as fast if you run over a nail.
