Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire Speed Rating

Question

Question:

The written description says this tire is M speed rated 81mph however the video description says it speed rating is 65 mph. Please verify the speed rating I am actually wanting a 145R12 Load E speed rating M with rim, but cant seem to find one. I already have the Kenda Load star and prefer the E rated on my pop up, though, I am actually no where near that weight on my new tear camper
