Man that sucks were your tires old or have cracked side walls, did you check your air pressure before you left?
I'd suggest go buy 4 new Goodyears.
Had a similar experience leaving the dez with my buddy's rig one tire blew in the dirt as we were pulling out. We replaced it then the 2nd one blew on the same side on the freeway . We left the rig just off the off ramp a few miles, with all of our bikes in it because it was late and we only had one spare tire. Drove home it was only another 45 min left to get home. Got up the next morning got two new tires. Got them on the rig drove back in town he bought two other new ones too. When one tire goes it places all the weight on the next tire causing it to over heat and exploded that tire.
