As you all snow trac owners know I routinely speak against foam filled tires. well my Thiokol Brutis came with them half way into a 130 mile trip I had a blow out. sorry I have no pics I ain't got to take pictures while wearing my MacGyver hat ankle deep in overflow. after a few calls this morning I found a br 300 solid tire in anchorage and will purchase a second one for the other side seems the bombie rims are quite a bit heavier than the old Thiokol 2 piece wheels. next I will go to disassembling the old foamy tires and replace them with alpine guide pneumatic units. mainly because they are cheaper to ship a tire and tube through the mail. I really have no problems with pneumatic tires as long as they aren't 20 years old,and that is a problem with most of those second hand tires. the other thing alpine guide told me is the place filling those tires should be charging the tires around 110 psi if they only do 30 psi they will separate like mine did . I will post some pics of the trip when the job is done I have only had about 4 hours of sleep in the last 36 hours.
