This makes no sense.
UTQG temperature ratings are essentially a step speed test. If yu pass an "A" level, then the speed rating should be fixed - and while it has been a while since I looked at this, I think ALL A rated tires would be at least H rated.
What I suspect is that either the tire manufacturer OR Tire Rack is simplifying the UTQG ratings for the entire line. If Tire Rack is doing it, it's a simple mistake. If the tire manufacturer is doing it, it's just confusing, but not illegal.
