My left front tire on my 2005 F350 4x4 is losing 2 - 3 pounds of pressure a day. The set has 40,000 miles on them with about 6/32 inch of tread left. The spare is unused. Would you:
- Repair the tire and put it back on a: the front, b: the rear.
- Repair the tire but replace it with the unused spare tire, making the repaired tire the spare tire.
Two more notes:
- 9 months of the year I pull a 13,000 pound 5th wheel RV; it mostly sits the other
- In a year or less I'll need a new set of tires anyway.
TIA, no email please.
