What is as 2010 crew cab lariat? If it is an F150 you need to get a truck like a F250 or F350 otherwise you are going to end up in a ditch upside down like many others without an adequate tow vehicle. If you don't have an adequate TV 10 wd hitches wont help.
Read what it says on the tire side walls for PSI. If that is too confusing then contact the tire manufacturer and ask. So what is the point you are trying to make about the tire temp? What is the max temp rating on your tires? Was the temp of the tires higher than the temp rating, if not then the temp is not a problem? Beware of the tire expert wannabes personal opinions they will not pay for tire damage their personal opinions cause.
Over or under inflation will cause the tires to overheat and damage the tire. If it says 110 then that means 110. If it is supposed to be something else then it would be on the sidewall. Contact the manufacture and ask. Don't go by the personal opinions.
