different options have different pressures.

I’m not a gear head so this is very helpful! Mine clearly states 35 PSI but I never tow and truth being told since I’m retired I don’t drive it much either. 7000 miles in 21 months. But I have noticed that the steering tends to lane float so I may do the chalk test and lower the PSI a little to experiment.

Paul another thing you might want to do is get a battery maintainer. There's a lot of parasitic draw with all the tech and if you're not driving much the battery isn't getting fully charged. I used my Ford points and got one there but these two are very good.
The Ford one is this CTEK rebranded for Ford.

I bought tires at a local shop a few weeks ago. I didn't tell them what pressure to set, because I had no history on these tires, never owned Michelins before, never ran a 255/70-18 before, and assumed they knew what they were doing, being a tire shop.
I didn't check them before going on, assuming they would set them 75-90% of listed sidewall info which is 50psi max cold pressure. I was going to run them a few days see how they perform, then make an adjustment if required.
Took about 30 minutes @ 55mph for the computer to display the TPMS which showed 37, 43, 46 & 53. WTF. I could see maybe 3lbs variance, but 16 lbs is ridiculous.
I've been running them at 42 since adjusting them after the first trip, and they seem good so far. The forecast has a half inch of snow every morning next week, so that will be be a good test.

As far as I know, the SuperCrew calls for 35 and the SuperCab calls for 30.
I'm OCD about tire pressure and check them a couple times a week and every time I get gas. I double check them EVERY time they've been messed with at the dealer or tire shop and they're often incorrect. Surprisingly a lot of dealer techs think they should be inflated to the max psi on the sidewall, which is way too high.

Okay. I did run across someone here a while ago with the same model and tires as I have but he had a SuperCrew that called for 35 and my SuperCab calls for 30. STX, 255/65-17 tires.

I have a smart (ish) 4 amp charger, not a true battery maintainer but it works well so thanks for reminding me of that. Going out to the garage to hook it up right now.
When I first got my Ranger I disliked the Auto Stop Start feature enough I bought one of the plug-in devices to over ride it. As it is now I don’t really even need it since the battery doesn’t stay fully charged unless I put the small charger on it.

I should have mentioned it on my first post but big surprise, me forgetting something…. My truck is also the super crew and has the 255/65 R17 stock factory tires.
