I indicated that I might still use the split rims if the tire shop would mount new tires on them.....well I took one of the spare split rim wheels and mounted it on the truck,as the outer, so that I would have two original split rims on one side......As I started to inflate the tire, I got it to about 35-40 lbs and I heard a crack....I stepped away as I knew what was going to happen.....sure enough moments later, I heard what sounded like a shot gun blast and a cloud of dust.... the rim blew apart from being rusted where the rust could not be scene......will get a pic of that rim as well......Needless to say the split rim days are over for the truck......
