I have a 2010 F150 XLT 4x4. It still has the original tires, P235/75R17, plus a full sized spare of the exact same type and size. A couple of weeks ago I had a flat (rock cut), and had the tire repaired. I would rather not take long highway drives on that tire any more, but rather use it as the spare. The tires that have been on the road still have 3/16" tread, but the only once used spare has 3/8" of tread. Would it hurt my truck if I swapped the nearly unused spare to one of the aluminum rims and used the repaired tire as the spare? Would the tire with 3/16 more tread make enough difference to damage the drive train?
I get ambiguous "it depends" answers from tire dealers and our dealership.
