Replacement Inner Tube Recommendation for Trailer Valet XL to Replace Leaking Tire

I recently bought one of these and use 2-3 times so far. It has been extremely useful in backing up my trailer into a corner. However, on the last use one of the tires starting leaking while on a slight incline. Luckily, I was able to lower the jack and stop it in place. Not sure what happened, now the tire holds pressure for few minutes and starts hissing right away once it moves. Tongue weight is 450lb, well under the limit. The part is barely a month old, not sure what my options are. Thanks for your help !
