- Pentastar 3.6
I'm currently running Yokomaha Geolandar X-ATs (295/70R17), which are a shade over 33" in diameter. I have 3.55 rear gears, oh, and a Pentastar up front (2021 Classic Tradesman QC 4x4). Driving around town, I'm averaging a hand-calculated 18-19, and will touch 21 on the highway if not hauling. I saved my factory "All-Terrain Tires" (LT265/70R17E), and as the Geolandars are about run out, will probably put them back on and recalibrate my speedometer again. Mainly to avoid having to drop $$ on a new set right now. I'll probably see a 1-3 MPG increase based on what I was averaging before putting the bigger tires on.
I had a 5.7 in my previous 2015 RAM 2500 longbed/single cab 4x4. It got a consistent 13-14 MPG, but it was a much heavier truck. Didn't need it after we retired and sold the farm and got $4K less than I paid for it new due to used truck prices skyrocketing in 2021. It had about a dozen recalls over the six years I owned it - never had anything actually fail, though.
The Pentastar pulls my 1950 Ford 8N on a 7K axle trailer just fine, but it's definitely not as stout as the previous truck. It suits my current use-case quite fine, though, and the V6 has an excellent reputation. Zero issues with my truck in three years and 42K miles.
