30 years of going to Blythe, only had one flat thank God. Found out the spare was the wrong bolt pattern. Always ran low profile passenger car tires too. 30 years later I get a new boat and the first thing I did was put on 4 new trailer tires b4 the first river trip. Almost left town with a buster wheel bearing retainer after BigO assured me everything was good to go. Made the trip on time anyway. When you gotta go you gotta go.
