Tire pressure on 37PP

[MrLiou168]

What are y’all running for tire pressures (cold, nothing in the bed)? My truck got delivered at 50 psi all around and I’ve lowered them down to 38. Rear tires now have “chicken strips” - doesn’t look like the inner and outer 1.25” of tread is being used at all.

My gen 2 on factory 35’s liked to be at 37F/36R. What are you guys and gals running for comfort on the gen 3?

36/34

42/42 when towing our Ember Overland 171FB. It’s a small trailer but built like a tank. Tongue weight around 600#.

I run 36 front and 34 rear on my 37” truck.

If inner and outer are not wearing lower tire pressure to increase a flat foot print. I don’t own a raptor yet for a few more weeks but I run my 305/70 r16 tires at around 30 for an even tread wear.

Look in the driver's door jamb. Ford engineers set the spec and printed it on a nice sticker for you.

Obviously not working. It is indeed a beautiful sticker but they set it for Joe Schmoe who might be carrying 300lbs in the bed and rear seat passengers all the time. That's not me, nor any of the other responders, it seems.

Looks like I'm going to try 36/34. Thanks!

I did 36 cold all around and still had only the rear middle and front middle wearing. Fronts looked even due to turning but when testing on a straight road it was still over inflated. I’m now at 33 all around, and the ride is much better. But I haven’t had a chance to drive more than about 2 miles. I set it this low bc temps here are still in the mid 60s at night when I set it but will begin to be 70-80 and onto 90 soon. So it’ll end up around 35 cold.

pressure’s lower than mid 30’s will result in increased wear, noise, heat and reduced mpg.

we run 40 all the way around in both our gen 2 and gen 3. Seems to work really well in both trucks! Granted we havent put any sort of daily driver mileage on either truck, but it rides and wears really well. I personally like the sidewall feel of more pressure, but then again I drive like an A hole
