i'm about to start my search for new tires....i have a 3124kb ...
i did place heavy duty truck mud flaps behind each wheel as a preventive
??? an idea i got from this site...i'm thinking of changing this to a welded steel
plate...
has anyone had an opportunity to do any analysis / investigation as to why
the marathons blow up???? I'm sure most of us are quite aware of temperature
and overloading etc.......
are there better options than the marathons ????

thanks bill s....
