I'm on the road traveling and my valero (back tire) is leaking?

So I'm on the road and we've only made 3 stops. 1 in Kansas Wichita around there. And another in Oklahoma and 1 in Dallas tx. And on the last stop we saw that the tire in the passenger back side was smoking and the back of the sports track ford truck was full of oil that the tire was leaking. Were headed to San Antonio. What can I do.

Umm seriously? Ever heard of using the spare? Aaa? Tow truck? If you don't have a spare you should not be driving on a road trip anywhere
