In particular, my experience with the 68RFE is that it will also run 200* in normal driving conditions. The person I hear significantly lower temps from also claims 100,000 miles out of a set of Michelins so they either have/had a real special truck or are full of it. Either way, those claims are suspect at best.
Mine consistently runs 168 towing or not. It will climb a bit in some circumstances, most dramatically when I'm climbing a forest service road grade in hot weather at lower speeds, but that's outside the norm. I assume at highway speeds the temp is held in check better because of good airflow. I've never seen it get up near 200 under any circumstances. I don't know if 2012 to 2015 makes a difference or not.
FWIW, I got 20k miles on my stock Firestones and will be lucky to get 35k on my BFG AT/KO2s. Maybe I need to get some of those Michelins you're taking about.
Interesting. Maybe I didn’t pay attention when my truck was newer but it seems that it has always been 200*+. If you look at Shiners original link, it is for a 2013 + 68RFE as they “run hotter than earlier models”.
Repeating myself, but I find it hard to believe that when EVERY modern vehicle I drive runs 200* normal operating and that is deemed as too hot. I can buy that with the older fluids but with the new synthetics I’m just not convinced.
I have no first hand experience running temps as cool as being reported and I drive multiple different cars every week.
