Has anyone had problems with the right rear tire and or axle on a Bison Alumasport?  WE blew a tire on a one year old trailer with barely 10,000 miles on it. (No we did not hit anything)  My horse ended up straddling the last divider in our 4 horse that had a 3" piece of steel sticking up with a bolt, spring and knob on the divider that releases the extension of that divider.  The entire bolt, spring and knob came out of the steel and ended up inside of his left hind leg.  Though we had checked the horses repeatedly after changing the tire, we were unable to see that he was still straddling the divider until we unloaded the horse in the fourth stall when we  got home.  Has anyone ever had this type of problem?  The tires were Carlisle tires and since this happened we have heard that some of the Carlisle tires have been recalled - how do I find out which ones?  Also, this is a terrible design for a divider.  The Bison is the only trailer we have found that has this type of divider - anyone have this type of problem.  My horse did not make it through the second surgery (the first to remove the bolt was successful) due to the tremendous bruising from landing on the divider and not being able to get off.

The dealer that we bought the trailer from doesn't care, the tire company has changed their mind from replacing all the tires and paying the medical bills to telling us to buy a new tire and send the blown out tire back (which we did, and Bison has not responded. 

Any help and direction would be appreciated.  I am thinking about talking to a lawyer.  I dont know if that is a good idea or not.

Thanks in advance for any help.  I am having a really hard time dealing with the loss of one of my best friends.

I'm sorry to hear this. Before I share my recent experience with Bison tires, let me say that in the past 2 1/2 years I've enjoyed the trailer, would recommend Dixie H&M to everybody, and plan to keep this trailer until I run out of horse stalls and upgrade to a bigger Bison.

I have a 2007 Bison Trail Express that was purchased new in April '07. We didn't have any problems with the factory tires until recently. We blew one on Labor Day weekend (rear driver's side) and came close to blowing another (front curb side) this past weekend. Lucky for us, we had appropriate spares both times and, on the second tire, a buddy pulling behind us let us know the tire was rolling weird so we caught it before it blew.

Both times it appeared the tire simply came apart and it has been suggested by friends and tire professionals that we send this second tire to Bison. I'm not sure about that though b/c I don't know what kind of mileage I should expect out of trailer tires. I hate to accuse someone else when I should chalk it up to "hey, tires go bad, right?" I suppose we could be at fault for not recognizing some warning sign but I'll tell you this. Before I go on my next ride in two weeks, the remaining two factory tires are getting replaced. This is just not something I want to worry about.
