I usually travel by myself and meet friends for vacations so being prepard for a blow out is important to me.

Last year I had a blow out and some of the tips I received from this site I felt was helpful.  The best one for me was to have a shovel so I could put it under the tire to help lift it up.  I don't think  I could have done it by myself with out it.  I also purchased a heavy duty lug wrench and have a pipe to extend it.  Loved my trailer aid! 

I also purchased emergency triangles since the trailer I bought is 8ft wide so I could be legal.  Was very glad I did because I was on a Missouri highway with no shoulders and didn't have an option to pull off the highway and had to change the tire on the highway.  It was the quickest I've every changed a tire and was very thankful I was prepared.
