Greetings:<br />A few months ago Tallman5281 posted a question about Carlisle ST tires. I have a tandem axel trailer equipped with disc brakes for my Grady White 192. Yestderday I was towing the trailer home from getting the seats re-upholstered and one of the tires blew out. Today within 20 minutes of picking a spare along the way with the family to hit the water, a second tire blew out. These are all Carlisle 205-75 14D load range C tires. We keep the trailer fairly well maintained. Over the past 18 months, we have driven the boat on 4 major trips ranging from 500 to 1,400 mile round trips and the tires are not holding up - the tread is wearing down. The ones that failed did have worn tread, but the tread did separate. We live in Central Florida and frequent both coasts as well. I was in bind today and my lovley bride was insistent we replace all the tires - today. So went to a local trailer dealer and did so, but not where we purchased the boat& trailer.<br /><br />On that post from Tallman, somebody mentioned contacting the original dealer and Carlisle about this. I plan on doing this. I have scoured the board here and some people indicated their tires should last years. These tires were new 18 months ago and I am going to replace all of them as they are not lasting and they are wearing out fast. Any suggestions here????<br />Will a radial tire make a difference in how long they last?<br />Thanks for any ideas
