Do I need load range E tires?

[RjCorazza]

There are tuners available that allow you to reset the pressure at which the alarm goes off.

I have "E" tires on my F150 and E350. 40 psi is the max I run in those tires. The "E" range tires on my Jeep Wrangler run a max of 20 psi. Been that way for years with no problems.

I ended up getting a tuner last week to adjust the tpms settings. Worked like a charm!

Me too, on a leaf spring yj. Rough ride? Maybe, but not sure I can blame the tires.

What tires and load rating came with the truck? I would stick with that.

The tires that come with the truck, unless you spec out the heavy payload package, are optimized for smooth ride and good fuel mileage. If you drive dirt roads, haul heavy loads, or tow, those OEM tires are not going to do well.
