I have that very same tire on my 18' car hauler. The T designation means trailer use only, but they can be used in a truck. There was nearly the same tire (stock!) on a couple of 1981 Chevy 1/2-ton USAF trucks our squadron had in our pool. Wasn't real crazy about the way they drove on those skinny bias-plies, but they worked! The sidewalls are stiffer on a "T" tire, even more so than a "LT" pickup tire. And, that's why you should NEVER run "P" passenger-car radials on a trailer, especially a tandem-axle.

Yes, they'll work.
