For your 3170 the GVWR is 14500 lbs which is what you use for tire loading. The 22000 lbs is the GCWR which is the total load of your RV plus whatever you have in tow eg: trailer or small car. So your tires are technically OK for your unit.......

pure serendipity - My last flat was in mid-80's. We put over 60.000 miles on our last RV including the Alaskan highway and never had a flat. Tires were getting a bit worn at the end so the choices were new tires or new RV. We chose the latter
