I bought new tires 6 at a time, carried the extra 2 unmounted, AND USED THEM ALL TWICE over 2 years! Usually I would find a bulge or slow leak before I had a road breakdown.
I kept asking tire salesmen and techs how I could do a better job with the tires, and finally FOUR YEARS AGO one of them suggested moving up to G rated. Problem solved. I haven't had a flat since. He said my rims could handle the G rated tires even though they have a radius 1/2" larger than the E rated tires.
BTW, it appears that all the new Montanas come with G rated tires now.

Yes, our 2019 came with Sailun G load rating. It's my first big RV so I had never heard of a G rated tire but they seem to be bulletproof.
