I have a 2006 double cab with the 20 inch Enkei wheels added on as part of the XSP package. The spare under the truck bed is a 16 inch rim and tire. Seems like that would be bad to try to use that if I had a flat on one of the 20 inchers. Would it even work temporarily to get me to a shop where I could get the larger tire fixed or replaced? Does anyone have suggestions about a solution or work around before I go on a 1000 mile trip? Thanks for any info
