I haven't read all 7 pages, but I do have a couple of thoughts.
- ST tires have different speed ratings, but a lot of the radials I've seen are rated for 80+ mph.
- Speed differential is a factor in a lot of accidents. If you're on a freeway out west with an 80 or 85 mph speed limit, I'd bet you're safer towing at 70 than you would be at 55 provided your tires are rated for it and you don't have a marginal tow vehicle.
The only ST tires that I know are > 65 mph speed rating are the Carlisle RH (75 mph) and the Maxxis M8008 (106 mph). Never seen any other ST, bias or radial, with > 65 mph rating.
FWIW, it seems that Carlisle has backed off on its speed rating since it first came out, unless Discount Tire had/has bad info. I thought it was R, same as Maxxis, 3 years ago, then was N (87) a year later, but is now listed as L (75).
