The best trailer tire we offer in the size you need of ST185/80R13 is the Westlake # LHCK105 as it has automotive style tread for maximum traction, a higher speed rating at 75 mph, and comes with a 2 year roadside assistance program. It's also very highly reviewed by our customers who have it. I attached a review video for more info on it as well.
