'21 RAM Big Horn 3500 DRW CC/LB 4x4 with NEXEN Tire WOES!

Yes, GOOGLE does provide many different manufactured tires in size LT235/80R17E. GOOGLE also provides a lot of links to Michelin tires in the same size. Problem is the only model Michelin tires in that size I can find in stock are the Energy Saver, LTX A/T2 and Agillis. Checked with lots of online tire stores and even called local shops, but NONE have the Michelin LTX M/S2 or Defender LTX M/S in stock. Therein lies my dilemma...
