I think I did all I could do in the tire department:
- New Sailun S637 235/85R16 (DOT 0517) replacing Provider 10 ply. Bought 5; one for the spare
- New HiSpec 6.5" wide wheels to give the recommended width for the tire; bought 5
- Metal valve stems
- Lug-centric balanced
- TPMS TireTracker TT-500
- Harbor Freight infrared thermometer
See, I listen to all you guys!
Tires from simpletire; wheels from recstuff. Found "Best One Tire & Service of Mid America" to mount and balance. $1 per inch! Out the door for all 5 mounted and balanced for $90! Put them on the 5er myself at home.
