RoadRunner,
Don't be too hard on DanandBrenda.
In 2015-16 (and many other years) the factory was sending out these heavy rigs with 'E' rated tires @ 80 psi.
That is what is listed on the sticker, too...
Some of us just have to be convinced
at how scary this is.
DanandBrenda,
I feel your pain. We were convinced...
Last year, on the way to the Fall Rally, on the interstate, no rest area near by, steel railings 10 ft off the roadway,
and semis rushing by in the near lane. Just lucky the blown tire was on passenger side.
Had to buy a pair of tires at the next stop just to make it to the Rally.
You have made a good choice with the TPMS, now invest in a set of 'G' rated tires. The wheels on your rig should be rated for 110# so you're halfway there.
I can recommend Sailun 637s. A quality tire that is value priced.
